The John Guest Collet Locking / Release Tool is a precision-molded 2-in-1 accessory designed to simplify the installation and maintenance of push-to-connect fitting systems. Engineered specifically for 1/4" and 3/8" OD tubing, this dual-ended tool allows technicians to easily depress the fitting's collet (the locking sleeve) to release the tubing in seconds. This is the only professional way to disconnect LLDPE, Polyethylene, or soft copper tubing from John Guest or compatible fittings without damaging the internal O-ring or scoring the outer wall of the tube.

In addition to releasing lines, the notched ends of this tool are designed to help "seat" locking clips into the collet for a permanent, vibration-proof seal. Its slim profile makes it indispensable for working in the high-density environments common in modern beverage dispense systems, such as behind soda fountain manifolds, inside narrow draft towers, or within compact under-sink filtration kits. Using the correct tool ensures that your fittings remain reusable and your connections remain leak-free over years of service.

Why Every Technician Needs This Tool: Attempting to release a pressurized or "stuck" push-fit collet with a screwdriver or pliers often results in a "burr" on the tubing. When that damaged tube is re-inserted, it slices the internal O-ring of the fitting, leading to a slow, persistent leak that is difficult to diagnose. This tool provides even, 360-degree pressure on the collet, ensuring a clean release and preserving the integrity of your expensive beverage hardware.
