The flange gasket is a sealing component used between flanged connections in boilers, burners, and piping systems. In boiler spare parts and burner maintenance, a proper seal is essential to prevent leaks of water, gas, or combustion products. This gasket is designed to withstand the temperatures and pressures typical of heating equipment. When servicing flanged joints, replacing the old gasket with a new one ensures a tight, leak-free connection. Whether you are working on a burner flange or a boiler heat exchanger, this gasket provides the necessary seal for reliable operation.
