Description
Overview
The Hydrofit 3/8" quick connect union connector is a simple joiner used to connect two lengths of 3/8" tubing in water filtration and plumbing setups. It is commonly used when extending lines, repairing damaged sections, or tidying up installations where pipe runs need adjusting. This fitting is built for clean, reliable connections without tools, thread tape, or guesswork.
If you are working on under-sink filters, fridge water lines, or inline systems, this union connector makes changes quick without pulling half the setup apart.
Where It Is Used
This fitting is commonly found in domestic and light commercial water filtration systems, including under-sink filters, fridge water connections, and inline carbon or sediment filters. It is also handy for temporary installs or upgrades where tubing lengths need to be altered on the fly.

How It Works
Each end of the fitting uses a push-fit collet system. The tube simply pushes in until it seats firmly against the internal stop. Once locked, the connection holds pressure without leaking. To remove the tube, press the collet in evenly and pull the tube out.
It is a straightforward solution that saves time during installs and servicing.
Installation Notes

Ensure tubing is cut square with no burrs
-
Push tubing fully into the connector until it stops
-
Tug lightly to confirm it is locked
-
Always check for leaks once the system is pressurised
