This is a countersunk hex plug, commonly used in heavy-duty truck air brake and trailer pneumatic systems.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It threads into an NPT port to seal off unused openings, and the recessed hex design allows it to sit nearly flush with the surface. These plugs are replaced when they leak, corrode, or when system modifications require a new seal.
