PU Series Union Straight Composite Push to Connect Fittings

Union straight composite push to connect fittings use to connect two tubes in the same direction in pneumatic applications. Also known as union straight push in fittings, are designed to allow for fast and easy connections and disconnections between plastic tubings. Union straight tubing fittings are constructed of three primary components: the plastic PBT body, the plastic release collar, and the NBR sealing ring.

The stainless steel lock claw design of union straight push in fittings ensure superior clamping with various types of pneumatic plastic tubing such as polyethylene (PU) tubing, polyurethane (PE) tubing, nylon tubing (PA) and teflon (PTFE) tubing.

Applicable Tubing O.D.: ø3mm, ø4mm, ø5mm, ø6mm, ø7mm, ø8mm, ø9mm, ø10mm, ø11mm, ø, 12mm, ø13mm, ø14mm, ø15mm, ø16mm, ø1/8", ø5/32", ø3/16", ø1/4", ø5/16", ø3/8," ø1/2", ø5/8"
