Lochinvar & A.O. Smith 100074230 Manifold Gasket B

Lochinvar & A.O. Smith 100074230 Manifold Gasket B is a sealing part that is used to ensure that the gas manifold and burner assembly of heating equipment stay connected without leaking. The gasket is a compressed seal between the mating metal surfaces, which prevents leakage of gases and ensures that there is an appropriate distribution of pressure to the burner ports of HVAC system. Its profiled sealing profile conform to the interface with the manifold and the mounting surface of the burner, forming a safe barrier in the combustion pathway. It is placed in burner and manifold connection space to aid in the regulation of gas flow and sealing when heating is on.
