Heater Hardware & Gaskets

Heater hardware and gaskets are the sealing and structural components that keep your hot tub heater assembly watertight and properly mounted. This includes heater unions, gaskets, manifolds, and associated fasteners. Worn or cracked gaskets are a leading cause of heater leaks, and replacing them promptly prevents water damage and heater failure.
