Function and Role â¤of the water⢠Supply Tubing in GE Refrigeration Systems
WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ X⣠6FT is a flexible plastic conduit that carries âpotable cold water from the household shutoff to the refrigerator’s ice maker and door dispenser. â¤Its⣠nominal 5/16″ diameter (â7.9 âŁmm) and 6 ft âlength make it â¤suitable for typicalâ underâcounter and behindâappliance runs; compatibility depends on the appliance âinlet and the shutoff fitting accepting âŁ5/16″ tubing or theâ use of the appropriateâ adapter.â In service the tubing’s role is purely hydraulic and⢠mechanical: it must provide an uninterrupted, âŁleakâfree â˘path for water â¤while resisting âmoderate household â˘pressures,⢠kinking during routingand chemical exposure from cleaningâ agents used nearby.
The tubing exhibits low âhydraulic resistance over shortâ lengths, but bends andâ kinks can drastically reduce flow⢠or create stress points that lead to leaks; thus maintain a gentle bend⤠radius and avoid sharp crimps. Use a square cut and fully seat the tubing inâ pushâfit or compression fittings, then verify each connection under pressure with a slow fill and observation for leaks.This âtubing âis intended â¤for cold potable water only and⣠should not be substituted for âhotâwaterâ lines or exposed to continuous high heat. Practical examples include replacing aâ kinked factory line when moving a refrigerator,extending reach between the âwater â˘valve and â˘inlet with compatible âfittings,or routing âthe line through cabinetry – in â¤each case confirm⢠fitting compatibility andâ inspect for abrasion⣠where the tubing contacts edges.
- Confirm inlet andâ valve accept 5/16″ OD tubing or use an âadapter.
- Cut tubing square, insert fully inâ fittingsand secure clamps where required.
- Avoid sharp âŁbends, protect against abrasionand pressureâtest after installation.

How the WR17X2891 GE Refrigerator Water Line Plastic TUBING 5/16″ âX 6FT Works Inside the Appliance
The WR17X2891 GE Refrigerator Water Line âPlastic TUBING 5/16″⢠X 6FT serves as the conduit for potable⣠water between the household shutoff and the refrigerator’s internal⤠water system âŁ(ice maker and dispenser). Thisâ tubingâ is a flexible, potable-grade plastic âŁdesigned to replace or extend factory lines; its 5/16″ â¤nominal diameter and 6-foot length allow routing through âcabinetry and hingeâ cavities without⣠requiring multiple joints. In â˘many GE â˘installations âthe tubing interfaces with standard compression nuts,⤠ferrulesor push-to-connect fittings at bothâ the supply and the âŁappliance â˘inlet, so â¤installers should confirm the âconnection type on âthe specific refrigerator model before installation.
Flow andâ mechanical behavior of the tubing depend on diameter,length,and routing: the 5/16″ boreâ provides â¤sufficient flow âŁfor ice production and dispenser use but can⢠be sensitive to sharp bends andâ kinksâ that reduce flow or cause pressure âŁloss.During installation, maintain a gentle bend radius, secure âŁthe tubing âŁwith clamps to prevent movement⤠and chafingand cut squarely with a⣠tubing cutter to ensure a leak-free seal with compressionâ or âŁpush-fit connectors. for practical examples, when replacing a copper line with âthis plastic tubing⢠use⢠the correct ferrule/adapter at the shutoff, route the line⢠away from hinge pinch points andâ cold⤠external â˘walls, âand pressure-test the assembly for leaks at both ends after⢠installation.
- Size and length: â˘5/16″ â¤diameter, 6 ft length for⢠routing â˘versatility.
- Connections: compatibleâ with compression nuts, ferrulesand many push-to-connect fittings when matched correctly.
- Installation practices:⢠maintain bend radius, cut squarely, â˘secure clampsand pressure-test.
- Environmental considerations: insulate or route away from freezing zones to prevent blockage.

Common Failure Symptoms and âŁDiagnostic Indicators for Water⣠Line Tubing (leaks, pressure loss, âscale and contamination)
The WR17X2891 GE âŁRefrigerator Water Line Plastic TUBING 5/16″ X 6FT is a replacement supply â¤line designed to convey â¤potable âwater fromâ the household â˘shutoff âto refrigerator valves, âfilters and⢠the âŁicemaker. The 5/16″ nominal â¤tubing â¤diameterâ is commonly compatible with GE-style compression fittings⤠and push-fit â˘connectors;⢠matching inner/outer diameter is critical for a leak-free seal. typical⤠failureâ modes for this tubing include âŁsmall pinhole leaks at stress⢠points, loss of cross-sectional area from mineralâ scaleand âkinking or deformation where the line is⢠routed-each of which alters hydraulic performance â¤and may affectâ ice production or dispenser flow rates. Mechanical wear⢠often presents as âvisible cracks or⣠flattenedâ sections near bends or fittings, â¤whereas scale and particulate contamination manifest as â˘reducedâ flow and changes in taste or discoloration ofâ dispensed water.
Diagnosing problems requires âboth âvisual inspection and simple hydraulic tests. Reduced flow or intermittent sputtering that clears âŁwith a short reverse flushâ points toward internalâ blockage from scale or debris; a steady drip at a connection usually indicates a compromised ferrule, nut,⤠or anâ under-sized tube seating.â Contamination indicators include brown/gray âparticulates, persistent foul taste after filter replacementor â˘visible biofilm⤠where theâ tubing connects to the refrigerator inlet; these signs justify isolating the line, â¤sampling downstream of the âfilterand âŁreplacing the tubing if⤠interior delamination or irreversible scaling is present. â¤For practical⢠troubleshooting, compare measured supply pressure and delivered flow against expected values, âinspect fittings âand âŁrouting for âŁkinksand replaceâ the tubing⢠with the correct 5/16″ diameter part when permanent deformation, cracks, â˘or inaccessible mineral buildup are found.
- Visible wetting/dripping at âfittings or along length (leak)
- Reduced âor intermittent âŁflow, airâ sputter (partial âŁblockage or pressure loss)
- White/gray deposits âor hard nodules â˘inside line (mineral scale)
- Discoloration, sediment in âdispenser,â or persistent off-tasteâ (contamination)
- Flattened/kinked âsections or brittle cracks (mechanical failure)

Q&A
What is WR17X2891 and what do the⣠dimensions 5/16″ x 6ft mean?
WR17X2891 is a GE replacement refrigerator water line – âa flexibleâ plastic tubing sold forâ supplying⣠water to ice makers and dispensers. The â”5/16″” refers to âthe tubing outside diameter (OD) and “6ft”⣠is⢠the total length. It is indeed a flexible, refrigerator-type âwater line intended to⣠be cut to length â¤as needed.
Is this tubingâ safe â˘for drinking âwater and ice makers?
Yes. This tubing is manufactured as a⤠refrigerator water line for⤠potableâ water use and intended for ice makers and water dispensers. For confirmation look for potable-water/NSF/ANSI labeling âon the package or product spec⣠sheet; if in doubt, replace with tubing explicitly marked safe for drinking water.
Which refrigerators is⢠WR17X2891 compatible with?
WR17X2891 â¤is an OEMâ GE replacement part used on many GEâ refrigerators. Compatibility depends on the model âŁand â¤installation configuration. Always confirm fit by checking your refrigerator⤠model number against the GE parts list orâ cross-reference the part â¤number with the seller or GE Parts website before purchasing.
Can â¤I cut or shorten the tubing and how should â¤I do it?
Yes. You can⢠cut the â6 ft tubing to length. Use a sharp plastic tubing cutter or a⢠very⢠sharp utility knife⣠and make a square, âclean cut to avoid leaks. Remove any burrs or uneven edges before attaching fittings. Do âŁnot crush âor⢠flatten the tube whenâ cutting or handling.
Willâ 5/16″ tubing fit my existing 1/4″ fittings?
Not directly. 5/16″ âŁOD tubing is larger than the common 1/4″ OD size used onâ some refrigerators. To⢠connect â¤different sizes⤠you â˘mustâ use a properly sized adapter,compression coupler,or a pushâtoâconnect fitting designed for the two OD sizes. Always use fittings ârated for potable water and the correct⢠OD â˘toâ ensure â˘a leak-free connection.
How do I installâ WR17X2891 safely?
Turn off â¤the⣠refrigerator power and the water supplyand relieve pressure at the line (open dispenser or a âdownstream valve). routeâ the tubing without sharp bends or kinks, secure âŁit with clips or straps,â cut square, âŁand attach with the correct fitting type (compression or pushâtoâconnect) tightened to manufacturer torque⤠recommendations.Turn the water back on âand check all joints for âŁleaks. If uncertain about steps or⢠shutoffs, consult a technician.
Can I extend orâ splice â¤the tubing if I need more length?
yes, you can splice⣠or âextend âit using⤠a proper coupling or compression⢠union rated for refrigerator potable-water tubing and the same OD. Though, each joint introduces aâ potential leak point – when possible use a single continuous length sized correctly.If you need significantly more length, it’s frequently enough better â˘to purchase the appropriate longer tubeâ or a kit designed for extension.
Whatâ commonly⤠causes leaks with this tubing and how â¤can I prevent âthem?
Common causes: improper or uneven cuts,loose or âŁincorrect fittings,kinks âor crushing of â¤the tube,damage⤠from abrasion,and freezing. Prevention: make clean square âŁcuts, use âthe correct-size âfittings âand tighten per instructions, route the tube to avoid sharp bends and rubbing, use elbow adapters where needed, âinsulate or protect theâ line from freezingand inspect joints after installation for signs of leakage.
