Model PMGK-101B Panel Mount Gasket Kit
This Panel Mount Gasket Kit permits the installation of a Model 101B Universal Mount Unit through a cutout in any surface or door of a protected enclosure. As installed in this manner, the unit becomes an integral part of the protected enclosure, rather than being mounted externally at a perpendicular angle. Consider this kit to boost the ergonomic appearance of a protected enclosure, to minimize the overall foot-print of a protected enclosure in confined spaces, or to minimize exposed mechanical surface areas in clean rooms.
The Model PMGK features an adhesive backed unit mounting plate gasket and an enclosure pressure gauge gasket to provide a positive seal. It also includes a stainless steel bulkhead unit to provide a source of protective gas to the unit regulator and a stainless steel female bulkhead union and vent fitting to reference atmospheric pressure.
To utilize a Model PMGK on a universal mount pressurization or purging unit, an installer must perform a simple modification to reverse the locations of a tubing connector fitting and a vent fitting on the back of the enclosure pressure gauge. The sealing gaskets must then be applied to unit mounting plate and enclosure pressure gauge to form a seal resistant to rain and light wash down.
Universal Units may be ordered from our factory with this kit pre-installed.

Please note Best Purging Systems Corporation is not affiliated with nor accredited or certified by the National Fire Protection Association. Our guidance, recommendations and education regarding requirements of NFPA Code 496 are based upon over 80 years of combined experience as accumulated by our Senior Staff Members, as they've served both our many loyal clients and the NFPA as voluntary contributors and technical committee members,
Just like he did back in 1985, when he wrote America's first guide for enclosure purging and pressurization, our CEO and founder, Mike Baucom, recently wrote America’s first definitive ASHRAE Guide for HVAC in Hazardous Spaces. He undertook this effort on behalf of our sister company, Bebco Environmental Controls, with the extremely dedicated support of many fellow ASHRAE Technical Committee members. This ASHRAE Guide outlines numerous techniques and methods developed over time by countless experts within specific fields of interest.
To support ASHRAE and promote this new guide, we're offering a complementary copy on this website for a limited time. However, please note we anticipate a significant number of requests, so please act now!
