5303931779 Frigidaire fill Hose Washers (PKG 100) are a bulk pack of small sealing washers intended for use at the water inlet connections of Frigidaire and similar household appliances. These components function as compression or seat seals between a fill hose and its mating fitting, typically molded from elastomeric or engineered polymer materials to provide a water-tight interface under normal operating pressures.
Inside an appliance, the fill hose washer forms a primary seal at the junction between the water supply hose and the appliance’s inlet fitting or valve. it directly interfaces with the inlet valve, hose connector, and hose ferrule, and must resist mechanical compression, temperature cycles, and exposure to chlorinated or treated water. Proper selection and installation of the washer preserve system pressure, prevent leaks at threaded or push-fit joints, and reduce stress on the inlet valve assembly during normal fill and shutoff cycles.
In this article you will find a technical overview of the washer’s intended function, guidance on determining compatibility by inner/outer diameter and thickness, common failure symptoms (such as progressive leaks, intermittent filling, or visible hardening and cracking), basic troubleshooting checks to confirm a failed seal, and practical replacement considerations such as material compatibility, measuring for correct fit, and reasons to carry bulk quantities for field service. The discussion emphasizes diagnostic indicators and selection criteria technicians, engineers, and appliance owners can use when assessing or replacing these seals.

Function and Role of Fill Hose Washers in Frigidaire Water Inlet Assemblies
5303931779 Frigidaire Fill Hose Washers (PKG 100) are flat rubber sealing gaskets used at the hose-to-inlet interface of Frigidaire water inlet assemblies to maintain a watertight connection under intermittent household water pressure. these washers compress between the fill hose fitting and the inlet valve housing to block leakage paths created by surface irregularities or thread gaps; their sealing performance depends on correct diameter, sufficient compression, and the elastomer’s resistance to hardening and chemical attack. Technicians will find these washers packaged for high-volume service work: the part is intended as a direct replacement for the small rubber seat at the hose tail and is compatible with typical Frigidaire inlet-valve geometries when the nominal internal and external diameters match the hose nipple and valve bore.
The mechanical role of the washer is to provide a conforming, resilient barrier that tolerates cyclical wet/dry conditions and temperature variation without extruding or cracking. Common failure modes include compression set (permanent flattening), surface cracking from ozone or UV exposure, and swelling or softening from prolonged contact with certain detergents; any of these will allow leaks or require repeated retightening. for installation,ensure mating metal/plastic surfaces are clean and free of old sealant,fit the washer so it seats flat against the valve face,and tighten fittings to the manufacturer’s torque or hand-tight plus quarter turn-over-tightening can cut or extrude the washer. For service diagnostics and part selection, consider replacement when visible deformation, leaks at the hose joint, or intermittent fill faults are present.
- Primary functions: create a resilient seal, accommodate minor surface imperfections, and resist compression set during normal inlet valve cycles.
- Failure indicators: visible cracking, flattened profile, or persistent leak at hose connection despite correct tightening.
- Service notes: match nominal washer dimensions and elastomer type to the inlet assembly; replace washers during hose or valve replacement to restore reliable sealing.

How 5303931779 Frigidaire Fill Hose Washers (PKG 100) Work Within the Inlet Sealing and Flow‑Control System
5303931779 Frigidaire Fill Hose Washers (PKG 100) are elastomeric sealing rings used at the interface between an appliance inlet hose and the water inlet valve or hose fitting. in the inlet sealing and flow‑control system they act as a deformable gasket: when the hose nut or clamp is tightened the washer compresses against the valve seat and hose ferrule to form a fluid‑tight seal while maintaining the internal flow passage. Properly sized and softened washers compensate for minor surface irregularities, prevent progressive wear of metal seating faces, and reduce the need for overtightening that can distort valves or crush hose ends; they are designed to avoid intrusion into the flow bore so that nominal inlet flow rates remain unaffected when the washer is correctly installed.
- Material and behavior: elastomeric (EPDM/neoprene variants) chosen for water resistance and compression set resistance.
- Sealing action: compresses to fill gaps without blocking flow; shoudl seat flat against both mating surfaces.
- Failure symptoms: leaks at low torque,intermittent reduced fill,or extruded/deteriorated washers causing erratic sealing.
- Service tips: replace in sets when servicing fittings, seat washers dry or with a thin film of water, and avoid using oversized or degraded washers that can obstruct the inlet bore.
In practice, technicians replace these washers as part of routine inlet service becuase age, chemical exposure, and repeated compression cause hardening, cracking, or permanent set that compromises sealing and flow stability. A washer that has lost elasticity can either allow slow leaks at the hose connection or,if partially extruded into the bore,create pressure losses that lengthen fill times or trigger water‑level controls incorrectly. Compatibility considerations include matching inner and outer diameters to the valve stem and hose ferrule geometry-OEM replacement 5303931779 units are sized to Frigidaire inlet fittings, while aftermarket equivalents should be checked for cross‑section and thickness to ensure they do not alter the intended compression gap.

Common Failure Symptoms and Diagnostic Procedures for Leaks, Flow Restriction, and Seal Degradation
5303931779 Frigidaire Fill Hose Washers (PKG 100) are flat elastomeric sealing washers used at the hose-to-valve and hose-to-appliance interfaces to create a compressive seal under typical household water pressures. These washers function by deforming to fill microscopic surface irregularities on the mating faces; they are compatible with standard appliance supply hose couplings used on many Frigidaire top- and front-load machines and aftermarket hoses that use common 3/4″ threaded fittings. Typical failure mechanisms are mechanical tear, compression set (permanent flattening), hardening or embrittlement from chemical exposure, and extrusion into the bore under high pressure; these lead to leakage at the swivel joint or the valve inlet and can coincide with debris trapped against the washer that compromises the seal or partially restricts flow.
- Continuous or intermittent drip at the hose swivel or valve connection when the fill valve is pressurized.
- Substantially longer fill times or reduced flow rate without upstream pressure loss.
- Visible cracking, flattening, or rolled edges on the washer after hose removal.
- Debris or mineral deposits caught between the washer and mating seat causing leakage or partial blockage.
Diagnostic procedure begins with a controlled visual and tactile inspection: depressurize, disconnect the hose, remove the washer and inspect for tears, thickness loss, hardness, or extrusion. For flow-restriction troubleshooting, remove the hose and measure volumetric flow into a bucket over a fixed interval to compare against expected fill-time; inspect inlet screens and the washer bore for trapped particles that will cause pressure drop. Verify seal degradation by comparing compressed thickness to a new washer (use calipers) and replace suspect parts with washers of identical inner/outer diameter and thickness to restore proper compression. When conducting pressure tests,reassemble with a new washer and observe under normal supply pressure for several cycles; use only compatible lubricants such as a small amount of silicone-based grease if required to prevent pinching - avoid petroleum-based products that degrade elastomers.

Compatibility, Appliance Model Fitment and step‑by‑Step Replacement Considerations for Fill Hose Washers
The part identified as 5303931779 Frigidaire Fill Hose Washers (PKG 100) are flat rubber sealing washers designed to sit between the washer fill hose fitting and the inlet valve or hose connector to prevent leakage under axial compression. These washers are typically molded from water-compatible elastomers such as EPDM or nitrile (NBR) to resist chlorinated water and moderate heat; their sealing function depends on matching the washer inner diameter and thickness to the hose barb or male fitting so that the washer compresses uniformly rather than extruding under the hose clamp. compatibility across Frigidaire models and many OEM-compatible appliances is determined by the nominal inner diameter (ID), outer diameter (OD) bite, and material durometer; technicians should verify these dimensions against the appliance inlet and the hose ID rather than relying solely on part number interchange lists.
- shut off water and relieve pressure before disassembly.
- Remove hose clamp and inspect hose end and valve seat for corrosion, burrs, or old washer remnants.
- Measure washer ID/OD and thickness; install a matching washer so it seats squarely on the valve face or barb.
- Reassemble with moderate clamp torque to compress the washer without causing extrusion; perform a pressure test and inspect for leaks.
Replacement considerations include assessing material degradation (hardening, cracking, or permanent set), the condition of the mating seat, and whether the hose or valve face is damaged; replacing the washer on both ends of a hose run is common practice in service kits to ensure uniform sealing. Avoid excessive clamp torque that cuts or extrudes the washer and always clean mating surfaces to remove mineral deposits; because these washers are sold in bulk as PKG 100,technicians can stock appropriate sizes for field service,but must still confirm size and material compatibility for each appliance model before installation to prevent repeated failures.
| Item | Description |
|---|---|
| Inner diameter (ID) | Must match hose barb or fitting bore so the washer compresses evenly and centers on the seat. |
| Material | EPDM/NBR commonly used for potable water resistance and compression-set properties. |
Q&A
What is the 5303931779 Frigidaire Fill Hose Washers (PKG 100)?
It is a bulk pack (100 pieces) of replacement rubber sealing washers used at the water inlet/fill hose connection on Frigidaire appliances. These washers form a watertight seal between the hose fitting and the appliance inlet valve or hose coupling to prevent leaks.
Which Frigidaire models or appliances will these washers fit?
These washers are intended for use with Frigidaire appliances that use the same style of fill-hose sealing washer at the water inlet (for example many top-load washers and some refrigerators with water/ice connections).Compatibility varies by model and year; always compare the original washer’s shape and dimensions to the replacement or check the appliance parts diagram to confirm fit.
What material are the washers made from and are they safe for potable water?
Manufacturers typically use a water-compatible elastomer such as EPDM or similar rubber for fill-hose washers as of good resistance to hot water and household chemicals. material can vary by supplier,so if potable-water certification (NSF) or specific chemical resistance is required,check the product listing or manufacturer data to confirm the exact material and approvals.
What size are these washers and how do I measure the correct washer for my hose?
size is determined by the washer’s inner diameter (ID), outer diameter (OD), and thickness. To select the correct washer measure the ID where the hose post passes through, the OD to match the recess in the coupling, and the thickness of the original washer. If uncertain, remove and measure the original washer, or bring it to a parts supplier for comparison. The bulk pack is useful when you need multiple replacements but you should verify dimensions before installing.
How do I install a fill-hose washer correctly?
Turn off the water supply and disconnect the hose. Remove the old washer and clean the mating surfaces on both the hose fitting and the appliance inlet. Insert the new washer so it sits flat in the hose fitting’s recess (beveled face oriented per original, if applicable). reconnect the hose hand-tight and then snug with a wrench-do not overtighten, as excessive torque can deform the washer or damage threads and cause leaks.
Can I use these washers on other appliance brands or on garden hoses?
Possibly-if the washer dimensions and shape match the fitting. Many appliance and hose connections use similar flat rubber washers, but thread standards and recess dimensions differ. Always compare the washer dimensions and the fitting design; for garden hoses and outdoor connections, verify the washer matches the specific thread (for example garden hose threads) and intended sealing style.
How can I tell if a fill-hose washer needs replacing and what causes leaks?
Common signs are visible water leaks at the hose connection, a flattened or cracked washer, or a washer that no longer fills the coupling recess. Causes include age-related hardening/cracking of the elastomer, incorrect washer size, debris or corrosion on the mating surfaces, and overtightening that distorts the washer. Regular inspection during hose replacement will prevent most connection leaks.
How many washers will I need and does the PKG 100 make sense to buy?
The number you need depends on how many hoses and installations you plan to service-one washer per hose connection is typical. A 100-pack is economical for technicians, service shops, or homeowners who want spares, but may be needless for a single repair. Check return/warranty policies and confirm dimensions before purchasing a bulk pack to ensure the washers match your submission.
