5303931779 Frigidaire Fill Hose Washers (PKG 100) are small elastomeric sealing gaskets used at water-inlet hose connections on Frigidaire appliances.These washers provide the compression seal between a hose fitting or swivel nut and the appliance inlet or valve spud, preventing leaks and ensuring consistent water delivery. Typically supplied in service packs of 100, the washers are sized and specified to match common hose and valve geometries and are molded from materials chosen for water resistance and dimensional stability.
Within the appliance,the washer is positioned at the interface between the hose coupling and the inlet valve or fitting and therefore interacts directly with the water-inlet valve,hose,nut,and any strain-relief components. It is subject to hydraulic pressure, temperature cycling, and exposure to treated or mineralized water; those conditions influence compression set, hardness, and chemical compatibility requirements. Correct seating, appropriate compression from the connection torque, and the washer material’s resistance to extrusion and aging are critical to maintaining a reliable, leak-free water path and preventing downstream electrical or mechanical damage from moisture.
this article explains the washer’s intended function and key specifications, how to confirm compatibility with specific Frigidaire models and hose sizes, common failure symptoms to recognize (for example slow leaks, intermittent dripping, or loss of inlet pressure), and stepwise troubleshooting methods to isolate a failed seal. It also covers practical replacement considerations-selection of correct material and dimensions, installation best practices (shutoff and pressure relief, inspection of mating surfaces, correct torque and seating), and service tips for batch replacement-so technicians, engineers, and appliance owners can perform effective diagnostics and repairs.

Function and Role of Fill Hose Washers in Frigidaire Water Inlet Assemblies
the part 5303931779 Frigidaire Fill Hose Washers (PKG 100) are flat sealing washers used at the hose-to-inlet connection of Frigidaire water inlet assemblies to establish a reliable compressive seal between the hose fitting and the valve or coupling face. These washers are typically molded from elastomeric materials such as EPDM or nitrile compounds selected for resistance to chlorinated water and repeated thermal cycling; thier role is to deform under clamp or threaded compression and fill surface irregularities, preventing leak paths that would or else form from pressure and vibration. A service pack of 100 is practical for technicians who perform preventive maintainance or replace inlet hoses and valves, since the washers are inexpensive wear items that should seat flat and remain pliable to maintain seal integrity.
Under normal operating conditions the washers behave as deformable face seals: they accept a controlled compression (compression set is the primary aging mechanism) and must resist extrusion at the hose-joint gap. Common failure behaviors include hardening and cracking from ozone or heat exposure, permanent compression set that allows slow leaks, and extrusion in assemblies with excessive gap or overtightening. For practical replacement, seat a new washer flat against the inlet face, avoid petroleum-based lubricants that swell certain elastomers, and replace the washer whenever the hose or inlet valve is serviced to restore proper sealing geometry.
- Inspection checklist: check flatness, signs of cracking or compression set, replace if hardened or deformed.
- Installation tip: seat washer flat, tighten to a snug fit without deforming the washer.
- Service context: replace with each hose or valve swap; use matching material for chlorinated water service.

How the 5303931779 Frigidaire Fill Hose washers (PKG 100) Integrate with the Water Inlet Valve and Supply Hoses
5303931779 Frigidaire Fill Hose Washers (PKG 100) are precision-molded rubber sealing gaskets that fit inside the hose nut and compress against the water inlet valve spud to form a pressure-tight joint. The washers provide a static compression seal that compensates for small surface irregularities on the metal or plastic spud; the elastomeric compound maintains elasticity under normal household water temperatures and exposure to detergents, allowing the part to conform to threads and flat mating faces without cutting or extruding when properly installed.
Proper integration requires the washer to be fully seated in the hose nut and compressed evenly during tightening so the seal is generated across the entire contact face; insufficient compression results in weeping or pulsation leaks, while excessive torque can deform the washer or force it out of position. Technicians routinely replace these washers whenever a supply hose or inlet valve is disturbed-common failure indicators include steady drips at the hose connection, visible groove wear on the washer, or a nut that tightens without stopping leaks. Practical guidance and common attributes are listed below.
- Seat washer flat in the hose nut before assembling to avoid twisting or folding.
- Tighten by hand first, than complete with a controlled wrench turn to compress the washer evenly rather than overtightening.
- Replace washers after any hose or valve replacement; inspect for cuts, hardening, or permanent set.
- Match washer profile to the valve spud and hose nut to avoid mismatch that causes localized leakage.

Common Failure Symptoms and Diagnostic Indicators for Worn or Damaged Fill Hose Washers
Fill hose washers form the primary seal between a water supply hose and the appliance inlet valve; their role is to compress into the mating seat and stop water flow at the hose coupling interface. The 5303931779 Frigidaire Fill Hose Washers (PKG 100) are supplied as service replacements in bulk for field repair and maintenance, and are typically made from elastomers (NBR or EPDM) selected for water resistance and compression set performance.Compatibility is governed by washer profile and material hardness rather than brand alone: technicians should match the washer’s outer diameter and thickness to the valve cup and hose ferrule to restore a reliable seal. Practical use cases include replacing washers during hose swaps, after valve servicing, or when field inspection shows distortion or extrusion that prevents uniform seating under compression.
Failed or degraded washers produce distinct mechanical and hydraulic symptoms that guide diagnosis. A leaking connection that persists after properly torquing the hose nut, intermittent filling or slow fill rates, and an appliance that continues to draw water after the valve is closed are signs of an ineffective seal. Confirm failure by removing the hose and inspecting the washer for flattening, permanent set, cracking, hardening, or particulate hard deposits; a simple tissue or paper towel test while pressurizing the inlet can verify a slow leak. For quantitative assessment, measure washer thickness and internal bore with calipers and compare against a known-good sample; replace washers whenever wear or dimensional change exceeds the tolerance needed to form a continuous, concentric seal.
- Visible drip at the hose-to-valve joint despite correct torque
- Slow or intermittent fill indicating a partial seal
- Continuous inlet flow or overfill after valve actuation
- Physical signs: cracks, flattening, extrusion, or hardened surface

Replacement Considerations, Compatibility, and installation Procedures for Frigidaire Fill Hose Washers
The 5303931779 Frigidaire Fill Hose Washers (PKG 100) are small elastomeric sealing discs intended for use at the hose-to-valve and hose-to-fitting interfaces on refrigerators with water dispensers and ice makers. These washers compress between the metal or plastic fitting face and the hose end to form a static seal; common failure modes include compression set, hardening, tearing at the bore, and extrusion under high clamping force or elevated water temperature. materials are typically EPDM or NBR (Buna‑N), chosen for resistance to water and mild detergents; selection of the correct elastomer influences swelling behavior, compression recovery, and chemical compatibility with additives that can appear in household water supplies.
When replacing washers, match the inner diameter, outer diameter, and thickness to the original part and verify the valve seat surface is flat and free of nicks or corrosion that will prevent a uniform seal. Before installation, shut off the water and relieve pressure, then inspect the hose fitting for burrs or deformation; incorrect sizing or a damaged seat will cause weeping or intermittent leaks even with a new washer. proper installation practice is to position the washer flat against the mating face, tighten only to the point of seal without over‑compressing (hand tight plus a controlled wrench turn is typical for many fittings), and pressure‑test at normal operating conditions to confirm leak‑free behavior.
- Shut off water supply and depressurize before disassembly.
- Remove old washer and compare inner/outer diameters and thickness with the replacement.
- Clean mating surfaces, install new washer flat on the seat, and tighten to form a continuous compressed perimeter.
- Restore water and inspect under operating pressure for slow leaks or seepage.

Q&A
What is Frigidaire part 5303931779 (Fill Hose Washers) and what does it do?
These are small rubber sealing washers (gaskets) that sit inside the threaded ends of a washing-machine fill hose or inlet connector. Their job is to create a watertight seal between the hose fitting and the appliance water inlet valve or shutoff valve, preventing leaks at the connection point.
How many washers come in the PKG 100 and why would I need so many?
The package contains 100 individual washers. Packs this large are typically sold for service technicians, repair shops, or for facilities that perform many repairs-so you can replace the washer any time a hose is disconnected or shows signs of wear without buying single pieces.
Which appliances and hose types are these washers compatible with?
They are designed for Frigidaire washers (and compatible models) that use replaceable rubber inlet/hose washers. Many other brands use similar-size washers, so they can be interchangeable if the physical dimensions match. Always compare the old washer’s size and shape or check the appliance model’s parts list to confirm compatibility.
How can I tell if the fill hose washer needs replacing?
Common signs include dripping or spraying at the hose-to-appliance connection, visible cracking, flattening, hardening, or distortion of the washer, and leaks that only occur when water is on. if the washer is flattened or brittle, it will not seal properly and should be replaced.
What is the correct way to install one of these washers?
Turn off the water supply, disconnect the hose, remove the old washer, and seat a new washer fully inside the hose fitting or valve recess so it sits flush. A small amount of water or a drop of mild dish soap can help it slip into place. Reconnect the hose, hand-tighten, then give it a modest wrench turn-do not overtighten, which can deform the washer and cause leaks.
Can these washers be used on both hot and cold water lines and are they safe for potable water?
Yes. These washers are made from water-compatible rubber compounds (commonly EPDM or similar) intended for household hot and cold water lines and are suitable for potable water connections in appliances. Avoid petroleum-based lubricants during installation because they can degrade the rubber; use water or a small amount of silicone-based lubricant if needed.
Can I reuse the old washer or use plumber’s tape instead?
It’s not recommended to reuse an old washer because compression, cracking, or hardening reduces sealing effectiveness. Thread seal tape (Teflon tape) is for threaded pipe threads and will not replace the function of an inlet washer that seals inside a hose coupling-using both won’t compensate for a damaged washer. Replace the washer if there’s any doubt about its condition.
Any tips to prevent future leaks or premature wear?
Inspect and replace the washer whenever a hose is disconnected. Tighten fittings only to the snug plus a quarter turn-overtightening damages the washer. Keep washers away from petroleum products and ozone sources during storage. periodically inspect hoses and connections for wear and replace hoses that are cracked or bulging to avoid stress on the washer and valve fittings.
