About this product

Ensure a safe, reliable, and leak-free water supply with our heavy-duty RO Water Connectors. Engineered from food-grade, BPA-free polypropylene, these push-fit quick connectors are explicitly designed for high-performance reverse osmosis systems, under-sink water filters, and beverage dispensing setups.

Featuring advanced Push-to-Connect technology, this fitting utilizes stainless steel gripping teeth to firmly lock 1/4" OD water tubing in place. The integrated EPDM O-ring provides a dual-sealing barrier that eliminates leaks under pressure, even during water temperature fluctuations.

Whether you are bypassing a filter stage, extending your water lines to a refrigerator ice maker, or replacing old, worn-out compression fittings, this reverse osmosis connector delivers professional-grade durability. It is highly resistant to chemical corrosion and structural fatigue, making it the ideal choice for residential and light commercial water purification setups.

How to use it

How to Install (Push-To-Connect)

Prep the Tubing: Cut the 1/4" water tubing squarely and cleanly. Ensure there are no burrs, jagged edges, or scratches on the end of the tube.
Mark the Depth: Mark approximately 15–18mm from the end of the tube to know exactly how deep it needs to sit inside the connector.
Insert the Tube: Push the tubing firmly into the RO Water Connector collet until it passes the internal O-ring and hits the tube stop. Use your mark to verify it is fully seated.
Test the Lock: Pull back gently on the tubing. The connector's teeth will grip the tube, preventing it from slipping out.
Secure (Optional): Slip an RO locking clip behind the collet to lock the quick-connect mechanism in place.

How to Disconnect

Depressurise: Turn off the main water valve and open the RO faucet to relieve any trapped pressure in the line.
Remove Clip: Remove the locking clip (if one was installed).
Push the Collet: Push the small, outer ring (the collet) flat against the body of the connector.
Pull the Tube: While holding the collet down firmly, pull the water tubing straight out of the fitting.
