UNION CROSS (CPZA)

A Pneumatic Unequal Cross CPZA is a four-way pneumatic fitting used to split or combine the flow of compressed air, where not all connected tubes have the same outer diameter (O.D.). Key Features Four Ports: It has four connections, typically arranged in a cross shape, allowing air flow to be split from one source to three different lines, or combined from three lines into one. Unequal Diameters: The defining characteristic is that one or more of its ports are designed for a different size of tubing than the others. CPZA/PZA Series: The CPZA or PZA designation generally refers to a Union Cross fitting, which uses a push-to-connect or push-in mechanism for fast and secure tool-free installation and removal of pneumatic tubing. Function: It is essential for flexible system design where a main air line needs to branch into smaller lines to feed different components (like smaller cylinders or valves), or vice versa, ensuring flow continuity despite varying tube sizes.
