WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT is a pre-cut length of flexible plastic water tubing designed for use in refrigerator water adn ice delivery systems; it is a supply-line component that provides a controlled, potable-water pathway between teh household shutoff/supply and the refrigerator’s internal water-handling components. As a replaceable plumbing part, this tubing is specified by diameter (5/16″) and length (6 feet) to match the connection and routing requirements of certain GE refrigerator models.
Inside a refrigerator, this plastic tubing connects the external water supply to internal elements such as the inlet valve, ice maker, water dispenser, and inline filter if equipped. It interacts with fittings (compressions, push-to-connect, or barbed couplings), shutoff valves, and pressure-regulating elements, and must maintain adequate flow and pressure while resisting kinking, abrasion, and contamination. Proper material selection and correct diameter are crucial to ensure leak-free joints, compatibility with quick-connect or threaded fittings, and preserved water quality under the operating pressures and temperatures typical of domestic refrigeration systems.
In this article readers will find a technical overview of the component’s function and physical characteristics, guidance on compatibility and how to verify correct fitment for specific refrigerator models, common failure modes and symptoms (for example leaks, reduced flow, or visible damage), basic troubleshooting checks to isolate tubing-related problems, and practical replacement considerations such as required tools, appropriate fittings, routing and securing practices, and safety steps like shutting off and depressurizing the water supply prior to service.

Function and Role of the WR17X2891 Refrigerator Water Line in Ice Maker and dispenser Supply
WR17X2891 GE Refrigerator Water line Plastic TUBING 5/16″ X 6FT is a flexible plastic supply tube designed to deliver potable water from the household shutoff and inlet valve to the refrigerator’s ice maker fill cup and dispenser. As a dedicated conduit, the tubing’s 5/16″ nominal diameter and 6-foot length determine flow capacity and routing options; installers use the length to avoid excessive bending or stress on fittings while the diameter sets the baseline flow rate and pressure drop through the line. In practice this component replaces damaged or kinked lines,provides a low-permeability path that minimizes leak points,and must be matched to the refrigerator’s inlet fittings and compression/nut size to ensure a watertight connection.
The tubing’s behavior in-service is governed by hydraulic and mechanical factors: inner diameter and length control volumetric flow and fill time for the ice maker, while versatility and wall stiffness affect resistance to kinks and abrasion where the line passes through chassis openings. Proper installation requires a square cut, correct seating in the ferrule or push-fit connector, and secure strain relief to prevent movement at the inlet valve and ice-maker assembly; inadequate seating or sharp bends commonly cause slow fills or intermittent leaks.Typical checks and installation considerations include:
- Inspect for kinks, cuts, or soft spots before installation and route to avoid pinch points.
- Cut tubing squarely and deburr to ensure full engagement with compression fittings or push-fit connectors.
- Secure tubing with clips or clamps to prevent vibration and reduce stress on fittings.
- Verify compatibility of the tubing OD with the refrigerator inlet valve and any adaptors required.

How the WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT Works Inside the Appliance
The WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT functions as the low-pressure potable-water conduit between the household supply and internal refrigerator components such as the ice maker and water dispenser. This 5/16″ nominal-diameter tubing is supplied in a six-foot length to accommodate common cabinet-to-supply routing; it is indeed made from a potable-water-grade plastic formulated to resist routine kinking and chemical leaching within the temperature and pressure ranges typical for residential refrigerators. in practice the tubing interfaces with standard 5/16″ compression, barbed, or push-fit fittings used on many GE appliances, and must be cut squarely and seated fully in the fitting to establish a reliable seal.
- Material and rating: potable-water-grade plastic with flexibility for routing but limited resistance to freezing; verify OEM material if specific chemical or temperature resistance is required.
- Connections: designed to work with standard 5/16″ refrigerator fittings (compression ferrules, barbs, or push-to-connect systems).
- Installation considerations: maintain a smooth bend radius, secure with clips to prevent movement, trim ends square, and test for leaks at operating pressure.
| Item | Description |
|---|---|
| Nominal size | 5/16″ diameter, 6 ft length |
| Typical connections | Compression ferrule, barbed fitting, or push-fit |
| Use case | Supply line to icemaker and dispenser; replacement routing inside cabinet |
Behavior under service is predictable: the tubing will expand slightly under normal household water pressure and contract when drained, so routing should allow for small movement without stressing fittings. Avoid running the line near heating elements or sharp edges and prevent localized kinks by keeping bends gradual; a kink can reduce flow or cause a leak at the fitting. For a practical replacement scenario, measure the required run, cut the WR17X2891 tubing square, install the appropriate ferrule and nut for compression fittings (or push fully into a push-fit connector), hand-tighten and then apply the manufacturer-recommended final torque while checking for leaks at the joint under system pressure.
Common Failure Symptoms: Leaks, Reduced Flow, Kinks and Freeze Blockages
WR17X2891 GE refrigerator Water Line Plastic TUBING 5/16″ X 6FT is the flexible supply tube that carries water from the household shutoff to the refrigerator inlet for the ice maker and dispenser. The tubing’s nominal 5/16″ diameter and 6-foot length match many GE refrigerator installations, but its plastic construction trades flexibility for lower crush resistance compared with metal lines; repeated sharp bends, contact with rough edges, or improper compression at fittings can create pinholes, splits, or loosened connections that manifest as leaks. Reduced flow can result from a partial internal obstruction (scale buildup, debris), a localized reduction in cross-section from a kink, or an under-open supply valve; freeze blockages occur when an exposed run passes through an unheated area and the water column freezes, producing a full or partial occlusion that stops discharge until thawed or replaced.
- Leaks: visible wetting, drips at fittings, or water pooling beneath the fridge-frequently enough traceable to nicked tubing, worn ferrules, or loose compression nuts.
- Reduced flow: slower dispensing or weak ice production caused by kinks, mineral restriction, or reduced inlet pressure upstream.
- Kinks: sharp bends that flatten the lumen and produce intermittent flow loss or stress points that later rupture.
- Freeze blockages: hard, immovable sections where ice has formed; these often present after temperature drops in attached spaces or insulation failures.
Technicians should inspect the entire run visually and by touch for cold spots, flattening, or abrasions; perform a simple flow test by opening the supply valve and observing discharge at the refrigerator inlet or by disconnecting the line to verify unrestricted flow. For repairs, replace damaged sections or install the complete WR17X2891 line to restore original dimensions and routing, secure the tubing with clamps to prevent movement and sharp bends, and add insulation on runs exposed to low ambient temperatures to prevent freezing. Use correct ferrules and torque on compression fittings-overtightening can cut the plastic, while undertightening will leak-and if mineral scale is suspected, consider upstream filtration or routine flushing rather than partial internal reaming, which can weaken the tubing.

Compatibility, Replacement considerations and Troubleshooting Procedures for Installation and Leak Testing
The WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X 6FT is a factory-style replacement water line intended for supply to ice makers and chilled-water dispensers. this tubing is sized to mate with 5/16″ OD fittings commonly used on GE refrigerator inlets and typical shutoff valves; when replacing the line, match the outer diameter and the fitting type (push-fit, compression, or barbed) rather than relying solely on length. Material compatibility matters: use food-grade polyethylene or similar approved plastics and avoid joining dissimilar plastics to metal without the correct adapters and ferrules. Routing and securing the 6 ft length to prevent sharp bends, pinching, or heat exposure preserves flow and reduces stress on fittings during normal thermal expansion and contraction cycles.
Troubleshooting installation and leak testing is primarily verification of fit, seating, and line integrity. Perform a staged pressure test by opening the supply slowly, observing each fitting for seepage, and using a soapy-water solution to reveal pinhole leaks at joints; check the tubing run behind the refrigerator and at the back panel while the dispenser and icemaker cycle to confirm steady flow. If leaks persist after reseating or replacing ferrules, inspect the tube for kinks, abrasion, or brittle cracks and replace the WR17X2891 tubing if damaged; when converting between fitting sizes (such as, 5/16″ to 1/4″ or 3/8″), install the proper adapter and retest. Common troubleshooting steps include:
- Verify tubing OD and fitting type; replace or adapt only with compatible connectors.
- Cut tubing squarely with a tubing cutter and reinsert fully into push-fit or compression fittings.
- Secure tubing with clips to prevent movement and stress on connections.
- Perform a slow-pressure fill and inspect all joints with a soapy-water check or visual inspection during dispenser/ice cycles.
- Replace both the tubing and the mating ferrule or insert if leaks continue after reseating.
