The PMM Series bulkhead union is made for running a pneumatic tube connection through a panel, cabinet wall or machine enclosure. It has a push-in tube port at each end and a threaded center section with a locknut. Once mounted, it creates a stable connection point on both sides of the panel.
This fitting is useful in pneumatic control cabinets, automation equipment, packaging machines, assembly systems and other installations where air tubing needs to pass through a panel or partition.
