COMPATIBILITY & APPLICATIONS
When You Need This Fitting

This check valve is essential for any reverse osmosis system using an automatic shut-off valve. The 1/8" NPT connection threads directly into most standard RO membrane housings, while the 1/4" quick connect accepts standard tubing running to your storage tank or faucet. The 90-degree elbow configuration is particularly useful in tight under-sink installations where straight fittings would create clearance issues. If your RO system continuously drains water or cycles on and off without water being drawn, a failed or missing check valve is often the culprit. The plastic insert design provides reliable one-way flow control to maintain proper system pressure for auto shut-off activation.

💧 The check valve must be installed with correct flow direction—arrow markings on the valve body indicate proper orientation. Install it between the membrane housing outlet and the storage tank line for proper auto shut-off function.
