Heat Trap Fittings

Our exclusive Heat Trap fittings are designed to reduce stand-by energy losses from water heaters, and their dielectric waterway design works to prevent corrosion at the same time. The energy loss reduction is achieved by the seating of lighter or heavier-than-water balls when the water flow is stopped. Each Heat Trap Fitting also features safety relief ports to prevent accidental closure of the waterway.

Each fitting is self-cleaning, because the inert thermoplastic lining prevents lime and scale buildup. Also, our steel-to-plastic construction creates a dielectric waterway. By preventing galvanic local cell corrosion, it provides proven protection for all dissimilar metal piping connections.

Heat Trap Fittings are also furnished as hot water outlet anode holding devices and dip tube assemblies to provide additional functions at one low cost.
