Compatibility and Fitment
Match all three thread details before ordering. NPT, BSP and parallel threads can appear similar but use different thread forms and sealing methods. Check the female port, male end, panel opening, panel thickness, lock nut clearance and wrench access. Use a compatible thread sealant on the tapered NPT joints while keeping sealant clear of the air passage.

Compliance and Safety
Depressurise the circuit before removal. Clean and inspect the threads, then tighten the fitting on its hex with a backup wrench so the panel and connected line do not twist. Repressurise the system and check both threaded joints for leakage.
Trailer Applications
This bulkhead fitting suits truck and trailer pneumatic repairs requiring a fixed connection through a frame member or mounting plate. It may be used within air brake, air suspension or auxiliary air plumbing when the port sizes, thread standards and mounting arrangement match the existing circuit.
