Rebuild kit for the black Mebner 1-1/4″ vent valve on Promarks chamber vacuum machines built before 2008. The vent valve lets air back into the chamber after the vacuum and seal cycles to release the pressure.
Compatibility: Promarks chamber vacuum machines made before 2008, including SC-680, SC-800, DC-530, DC-640, DC-650 and DC-800 (for the DC-800, confirm your machine has the Mebner 1-1/4″ vent valve).
