Maxitrol KR-4812 Seal Cap W/Gasket RV47 48 52

The Maxitrol KR-4812 Seal Cap W/Gasket is a protective sealing assembly used to close the designated regulator adjustment area and maintain separation between the internal gas-control section and the surrounding atmosphere. It works together with its gasket by compressing the sealing interface when secured, restricting gas passage through the covered opening and preserving the regulator housing's closed configuration. Fitted over the regulator bonnet connection in HVAC systems, enclosing the adjustment area with a gasketed barrier at the designated point. Its sealed construction limits leakage around the covered section and supports consistent pressure-control conditions for compatible RV47, RV48, and RV52 regulators.
