3/8" to 3/8" Water Feed Valve for Reverse Osmosis Systems

Connect your reverse osmosis system, water purifier or drinking water filter to an existing cold water supply using a compact chrome-plated brass feed valve with an independent shut-off control.

Easy Connection to Your Cold Water Supply

This water feed adaptor provides a convenient 1/4" (6.35 mm) tubing connection from an existing 3/8" cold water supply, allowing a water filtration system to be installed without replacing the original isolation valve or making significant changes to the plumbing.

Featuring 3/8" female and 3/8" male threaded connections, the adaptor can be fitted between a compatible cold water isolation valve and the flexible hose supplying the kitchen tap.

The additional 1/4" outlet supplies water to the filtration system and incorporates an independent manual shut-off valve, allowing the filter supply to be controlled without interrupting the main tap.

How to Install the Water Feed Valve

The adaptor is designed to fit between compatible 3/8" threaded plumbing connections, providing a separate feed for your water filtration system.

1. Turn Off the Cold Water Supply
Close the cold water isolation valve located beneath the kitchen sink.

2. Disconnect the Flexible Tap Hose
Unscrew the flexible hose connecting the isolation valve to the kitchen tap.

3. Fit the Feed Valve
Connect the adaptor's 3/8" female inlet to the isolation valve and reconnect the tap hose to the adaptor's 3/8" male outlet. Ensure all sealing washers are correctly positioned.

4. Connect the 3/8" Tubing
Insert the filtration system's 3/8" tubing into the compression fitting and tighten the retaining nut according to the fitting manufacturer's instructions.

5. Restore the Water Supply
Slowly reopen the cold water supply, operate the filtration shut-off valve and carefully check all connections for leaks.

Important: For cold water installations only. Check that your existing plumbing connections are compatible with the 3/8" threads and that your filtration tubing has an outside diameter of 3/8"  ). Do not apply PTFE tape to connections designed to seal using flat washers.
