WR17X2891 GE refrigerator Water Line Plastic TUBING 5/16″ X 6FT is a flexible plastic supply tube specified for use with GE refrigerators; the designation identifies the part number, a nominal 5/16‑inch tubing diameter, and a 6‑foot length. As a component, it provides the physical conduit for potable water within the appliance and is manufactured to withstand the mechanical and thermal conditions typical inside a refrigerator cabinet and back‑panel routing.
Inside the appliance the tubing links the household water connection or service valve to refrigerator subsystems such as the water inlet valve, ice maker, dispenser plumbing and any inline filtering assemblies. It therefore interfaces with fittings, clamps, swift‑connect or compression connectors and the inlet valve body; its condition and routing affect water pressure at the dispenser and ice maker, leak integrity at connection points, and the potential for kinking or freezing when installed in cold or confined runs.
This article will explain the tubing’s function and typical points of use, how to verify compatibility with specific refrigerator models and fittings, and the common failure symptoms to watch for (pinholes, splits, kinks, reduced flow, and leaks at connections). It will also provide practical troubleshooting steps and replacement considerations, including selecting tubing rated for potable water and appropriate working pressure and temperature, recommended installation practices (routing, securing, insulation and connector selection), and basic safety checks to perform before and after replacement.

Function and Role of the Refrigerator Water Line Tubing in Ice Maker and Dispenser Systems
The WR17X2891 GE refrigerator Water Line Plastic TUBING 5/16″ X 6FT functions as the dedicated potable-water conduit between the household supply and the refrigerator’s internal fill and dispensing components. Its nominal 5/16″ diameter and 6‑foot length provide the common geometry required to reach inlet fittings, solenoid valves, and ice maker fill ports while keeping pressure drop and flow turbulence low enough for reliable fill cycles. In practical terms, the tube must preserve sufficient flow rate for a full ice maker fill and continuous dispenser operation; restrictions, kinks, or undersized connections increase head loss and can produce underfilled ice cubes or slow dispensing flow.
Behavior and compatibility depend on material flexibility, chemical resistance, and connector type. The plastic construction resists corrosion and mineral buildup compared with metal lines, but becomes brittle with age or freeze damage and is vulnerable to sharp bends that cause flow restriction or cracking. Installers should confirm that the tubing’s 5/16″ nominal size mates with the refrigerator’s inlet fittings or with appropriate compression/push‑fit adapters, and route the 6‑ft length to avoid pinch points and heat sources.Typical practical issues encountered during replacement include reduced fill due to kinking, leaks at mismatched fittings, and length-related excess head loss when routing long runs through cabinetry.
- Flexibility for tight routing and vibration isolation
- Nominal 5/16″ diameter for common GE inlet fittings
- plastic material resists corrosion but can age or crack from freezing
- 6 ft length provides reach; excess length can increase head loss
- compatible with compression or push‑fit adapters when connector types differ

How the WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT Interfaces with the Inlet Valve,Filter and Door Dispenser
The WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT functions as the flexible,low-pressure conduit that connects the household water feed to the refrigerator inlet valve,the internal or inline water filter,and the door dispenser.Its nominal 5/16″ diameter and six-foot length allow routing from the rear inlet through the cabinet and into the door with minimal splices in many installations.The tubing is typically a food-grade flexible plastic (commonly polyethylene) and interfaces with refrigerator components using push-fit collets, barbed fittings with compression ferrules, or quick-connect adapters; proper installation requires a square cut, full insertion to the fitting stop, and correct seating against the O-ring or ferrule to form a reliable seal.
At the inlet valve the tubing either slides into a barbed nipple and is retained by a ferrule or is inserted into a quick-connect collet where an internal grab ring and O-ring provide axial retention and sealing. In filter and dispenser connections the same principles apply, but adapter sizes and port geometries vary by model, so matching the tube end, ferrule and adapter is necessary to avoid leaks. Practical installation guidance: avoid sharp bends and kinks (maintain a smooth bend radius),secure the line across hinge points with clips to prevent abrasion,cut with a proper tube cutter for a square end,and perform a pressure check after assembly; replace worn ferrules or adapters rather then forcing mismatched fittings.
- Connection types: push-fit collet, barbed + ferrule, quick-connect adapters
- Installation tips: square cut, secure routing, avoid kinks, pressure-test
- Compatibility notes: match ferrule/adapter to tubing and component port

Common Failure Symptoms of Water Line Tubing: Leaks, Flow Restriction, Kinks and Contamination Indicators
The WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT is a flexible supply line designed to route potable water from the household supply to the refrigerator’s dispenser and ice maker. Its 5/16″ nominal internal diameter and six-foot length provide enough reach for typical rear or side installations; the tubing connects to standard refrigerator quick-connect or compression fittings and is intended to withstand normal household water pressures without collapsing.In service the tubing must maintain an unobstructed bore and intact exterior wall to preserve flow rate and prevent leaks; compatibility considerations include the type of fitting on the fridge,any inline filters,and routing that avoids sharp bends,pinch points,or proximity to heat sources that can accelerate material degradation.
Common failure modes manifest as observable leaks, reduced flow, or contamination of the water path and can usually be diagnosed by simple visual and functional checks. Inspect the tubing along its entire run for bulges, abrasions, or kinks and test flow at the dispenser and ice maker; intermittent dispensing, slow ice production, or discolored water are practical indicators of internal obstruction, biofilm buildup, or connector backflow. Use the list below to quickly correlate symptoms with likely mechanical causes and be prepared to replace the WR17X2891 tubing if the outer wall is compromised or if flushing and filter replacement do not restore normal operation.
- Visible drips or puddling at fittings or along the tubing – typically indicates a loose connection, cracked tubing, or failed ferrule/compression ring.
- Slow dispenser flow or reduced ice yield – suggests partial blockage from kinks, mineral scale, or internal collapse reducing effective bore.
- Whistling or hissing during dispense – often a valve or connection leak causing pressure loss rather than a full rupture.
- Discolored water,sediment,or off-taste – signs of contamination from aging tubing,backflow,or particulate ingress downstream of filters.

Replacement Considerations, Model Compatibility and Installation Best Practices for Refrigerator Water Line Tubing
WR17X2891 GE Refrigerator water Line Plastic TUBING 5/16″ X 6FT is a factory-style replacement water line designed to carry potable water from the household supply valve to a refrigerator’s dispenser and ice maker. The tubing’s nominal 5/16″ dimension corresponds to the line size used on many GE models, but compatibility depends on connector style (compression nut and ferrule, push-to-fit, or threaded adapter) and the refrigerator’s inlet geometry. When selecting this tubing as a replacement,confirm the refrigerator model number,inlet fitting type,and required run length; mismatched fittings or attempts to force-fit a different OD/ID will create leak and flow issues. For example, replacing a kinked or pinched line on a side-by-side GE unit typically requires matching both the tubing diameter and the ferrule style to ensure a reliable seal at the shutoff valve and refrigerator inlet.
- Verify model and inlet fitting type before ordering or installing replacement tubing.
- Prepare tubing ends by cutting square and deburring for proper ferrule or push-fit engagement.
- Route and secure the line to prevent kinks,abrasion,and contact with heat sources or moving parts.
- Pressure-test the system and inspect connections for slow leaks after initial installation and again after 24 hours of operation.
Installation best practices include using new ferrules and nuts with compression fittings or ensuring full insertion depth for push-fit connectors; do not reuse deformed ferrules or damaged O-rings. Support the line at regular intervals with clips or straps to prevent stress on fittings and maintain gentle radius bends rather than sharp angles, and avoid placing the tubing under suspension stress that could enlarge connector holes over time. After assembly, open the supply valve slowly to monitor for leaks, purge air from the line by cycling the dispenser and ice system, and tighten fittings only to the manufacturer’s recommended torque or until the seal is achieved without overtightening.

Q&A
What exactly is the WR17X2891 water line and what are its dimensions and material?
The WR17X2891 is an OEM replacement plastic water tubing sold by GE for refrigerator water/ice systems. It is marketed as 5/16″ × 6 ft – the 5/16″ refers to the outer diameter of the tubing and the length is six feet. The tube is a flexible plastic designed for refrigerator water use (commonly polyethylene or a similar potable-water-grade polymer). For exact material composition and certification details, check the product packaging or GE parts documentation.
Will this tubing fit my refrigerator?
It will fit refrigerators that use 5/16″ OD plastic tubing for the ice maker/water dispenser connection. Many GE models use this OEM part, but refrigerator designs vary. Confirm your model’s parts list or measure the existing tubing OD and connector type before purchasing. If your fridge uses a different OD (for example 1/4″ or 3/8″) or a different connector style,this part will not be a direct match.
Can I use this tubing for both the ice maker and the water dispenser?
Yes – the WR17X2891 is intended for refrigerator water supply lines and is suitable for carrying cold potable water to both icemakers and dispensers, provided the tubing diameter and connector types match your refrigerator’s fittings. It is not intended for hot water or other non-potable uses.
How do I install it and make a proper connection?
Shut off the water supply before you start. Cut the tubing squarely using a proper plastic tubing cutter or a sharp utility knife to avoid ragged edges. For push-to-connect (quick-connect) fittings, push the tube straight in until it seats fully – you’ll feel resistance and then a stop. For compression fittings, slip on the nut and ferrule, insert the tube, and tighten the nut per the fitting manufacturer’s instructions (usually hand-tight plus a partial turn with a wrench). After connecting, restore water, check carefully for leaks, and run water through the line to flush out debris or air.
Is this tubing safe for drinking water?
The tubing is supplied as a refrigerator water line and is intended for potable water service. Many OEM refrigerator water lines are made from potable-water-grade plastics, but certification (NSF/ANSI) can vary by production batch.If NSF/ANSI certification is vital to you, check the product labeling or GE documentation to confirm compliance before installation.
How resistant is this tubing to kinking, and how should I route it?
Flexible plastic tubing is somewhat kink-resistant but can be damaged by very tight bends. route the tubing with smooth, gradual curves and avoid sharp 90° bends or pinching points (doors, drawers, or tight clamps). Use clips or straps to secure the tubing and prevent strain. If the tubing kinks and restriction cannot be smoothed out, cut out the damaged portion and replace it or use an approved coupling – do not attempt to stretch or crease the tube back into shape.
Can I cut and splice this tubing to make it longer or repair damage?
You can shorten the tubing by cutting it cleanly. To extend or repair, use approved fittings/couplers designed for refrigerator water lines (push-to-connect couplings or compression fittings rated for potable water). Make sure any couplers are compatible with 5/16″ OD tubing and are rated for potable water. Splices introduce additional potential leak points, so keep joints to a minimum and pressure-test after installation.
What should I check if I have a leak after installing this tubing?
First, shut off the water supply. Inspect the cut ends for a clean square cut; a ragged or angled cut can prevent a good seal. Ensure the tubing is fully inserted into the fitting and that any compression nut/ferrule is installed correctly and tightened to spec. Look for cracked or damaged tubing, damaged fittings, or debris in the fitting seat.replace any damaged section or fitting and retest at normal household water pressure. If you’re unsure or leaks persist, contact a qualified appliance technician.
