A gasket is a sealing component used between mating surfaces in boilers, burners, and other heating equipment to prevent leaks of gas or fluid. Over time, gaskets can degrade due to heat and pressure, leading to inefficiency or safety hazards. Replacing a gasket is a routine part of boiler maintenance and burner repair. A quality gasket ensures a tight seal, improving system performance and longevity.
