The plug vents air from a product when filling it with hydraulic oil or releasing trapped high-pressure gas. Designed to be removable and reusable, the plug has a floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole. The seal does not rotate during installation, thus preventing galling of the seat.
The plug is manufactured from 303 and 15-5 stainless steel and is designed to withstand up to 56,000 psi and temperatures to 600°F.
