The PM16 Bulkhead Union Fitting is built for heavy-duty, maximum-flow panel connections in pneumatic systems requiring large-diameter air lines. Designed for 16mm outer diameter (O.D.) tubing, it allows air hoses to pass cleanly through cabinet walls, enclosures, or structural bulkheads while maintaining an airtight seal on both sides.
Constructed with high-strength nickel-plated brass and heavy-duty composite materials, the PM16 features an M28 mounting thread with dual hex locknuts for secure panel anchoring. Its stainless steel internal gripping claws and one-touch release mechanism make tool-free installation and tubing maintenance fast and reliable.
