Higher-flow white tubing for RO & water filtration 3/8″ OD polyethylene tubing for compatible quick-connect drinking-water systems This white 3/8″ outside-diameter polyethylene tubing is designed for compatible reverse-osmosis and point-of-use water-filtration systems. Its larger diameter can support higher flow with less pressure drop than typical 1/4″ tubing, making it useful for under-sink RO main lines, pressure-tank connections, inline filters, refrigerators, ice makers, and other 3/8″ OD applications. 3/8″ ODHigher-flow residential tubing size PolyethyleneFlexible tubing material WhiteC.C.K. tubing 3–50 ftChoose 3, 10, 20, or 50 ft Applications Use where a larger tubing diameter and higher flow are preferred 3/8″ OD tubing is commonly used in residential filtration systems where greater flow or reduced pressure drop is helpful. It works with compatible 3/8″ push-to-connect fittings and can be cut to the required length for installation, replacement, or repair. RO systems Under-Sink & Higher-Flow RO Useful for compatible main product-water lines, pressure-tank runs, post-filter connections, and other system locations designed for 3/8″ OD tubing. Other applications Filters, Refrigerators & Beverage Lines Suitable for compatible inline filters, refrigerators, ice makers, and water-dispensing equipment that accept standard 3/8″ OD tubing.

Country of manufactureTaiwan Listed package dimensionsN/A on current MyAquaFilter listing Listed package weightN/A on current MyAquaFilter listing SKUTU-38-W Compatibility checklist ✓Your fitting is designed for 3/8″ OD tubing ✓The application uses a compatible cold-water filtration line ✓The tube can be routed without excessive kinking or crushing ✓The selected length provides enough extra tubing for clean routing and future service Installation A square cut and full insertion are essential for a reliable push-fit connection 1 Measure the Run Route the tubing with smooth curves and leave enough extra length for future servicing. 2 Cut at 90° Use a tubing cutter or suitable sharp blade to make a clean, square cut without crushing or deforming the tube. 3 Push Fully Into the Fitting Insert the tubing straight into the compatible 3/8″ quick-connect fitting until it passes the internal seal and seats fully. 4 Check the Connection Give the tubing a gentle pull to confirm retention, then pressurize slowly and inspect the connection for leaks. Before purchase Good to know ! 3/8″ means outside diameter Confirm tubing by OD, not inside diameter. This product is not a replacement for 1/4″ OD tubing. ! Current page contains a size typo The old description says this 3/8″ tubing is compatible with components using 1/4″ OD tubing. It should state 3/8″ OD compatibility. ! Use with compatible push-fit fittings Do not assume compatibility with 1/4″ fittings, compression fittings, barbs, or threaded connections without the correct adapter. ! Cold-water use The current listing specifies a 40–100°F range. Do not use on hot-water lines. ! Pressure rating is not published The current MyAquaFilter page does not provide a manufacturer-verified maximum working-pressure specification. ! NSF wording needs exact-model verification The current page states NSF/ANSI 42/58/61 certification, but the exact C.C.K. manufacturer trade designation and applicable certification scope should be confirmed before using those standards as a product-specific claim. Confirm tubing outside diameter, fitting type, and application temperature before ordering. Specific NSF/ANSI certification claims should be published only after the exact C.C.K. tubing trade designation and certification scope are verified. Not sure whether 3/8″ tubing is the correct size? Measure the outside diameter of the existing tube or send a clear photo of the tubing and fitting. Ask a Water Filter Specialist
