The PZA04 Union Cross Fitting is a 4-way equal push-to-connect connector designed to split a single pneumatic supply line into three separate branches or combine four air lines at a central junction. Built for 4mm outer diameter (O.D.) flexible tubing, it enables fast, tool-free installation and removal in compact automation systems and air distribution networks.
Constructed with a durable PBT/composite resin body and stainless steel internal lock claws, the PZA04 delivers an airtight, reliable connection without causing flow restriction. Its compact cross design makes it ideal for tight control panel layouts, robotics air circuits, and pneumatic manifold setups.
