How to Install

- Push the outer diameter tube firmly into the opposite quick connect end of the reducer until it bottoms out in the fitting body.

- To disconnect, push the collet ring toward the fitting body while pulling the tube out in one smooth motion.
COMPATIBILITY
Designed For
This John Guest stem reducer is compatible with reverse osmosis systems, water filter housings, ice makers, refrigerators, beverage dispensers, and pneumatic equipment requiring tube size transitions. The acetal construction offers better performance than polypropylene alternatives in applications with elevated temperatures or demanding mechanical loads. Suitable for connecting taps, toilet fill valves, and any system where reducing tube diameter is needed within John Guest quick connect networks.
🔧 Pro Tip: Before inserting tubing, cut the end square with a sharp blade and remove any burrs. A clean, square cut ensures the collet grips evenly and the O-ring seals properly without leaks.
