Includes (1) 1 position base plate with 1/4” Brass inlet/outlet fittings and (1) Oxygen/Moisture/Hydrocarbon Trap

Cartridge systems make changing gas filters quick and easy. A base plate allows cartridges to be exchanged without introducing oxygen. Spring-loaded check valves seal when a filter is removed and open only when a new filter has been locked in place. There is no longer a need for loosening and tightening fittings every time a trap is changed and your system will not become contaminated during the process.
