Description
The Maxitrol KR-4812 Seal Cap W/Gasket is a regulator sealing gas-fired heating equipment with RV47, RV48, and RV52 regulators. It provides a closure for the regulator bonnet area, maintaining internal sealing and preventing gas leakage from the control section. The cap and gasket fit over the regulator housing and secure the top assembly during service work. In HVAC systems, furnace and boiler applications, it maintains stable regulator operation by preserving internal pressure balance and reducing gas escape, ensuring consistent burner feed and safe operation of the gas control assembly over extended service use.
