Designed for use with 4mm outside-diameter tubing in pneumatic and fluid control systems utilizing mixed universal thread sizes. Verify thread engagement and tube outer diameter before installation.
Push-to-connect fittings are installed by depressurizing the system and releasing any residual pressure before handling any line connections. Insert tubing fully into the fitting until it seats against the internal stop to ensure a leak-free connection. To remove tubing, press the collet ring inward while pulling the tube straight out. Confirm thread compatibility and torque hand-tight plus the manufacturer-recommended turns for threaded ends, and verify all connections with a pressure test before returning the system to service.
