Ensuring a leak-proof seal during routine maintenance or heater rebuilds is non-negotiable for commercial service technicians. The Lochinvar & A.O.

This box of 50 gaskets is the designated direct replacement for 9000308005, providing a precise fit for high-demand electric water heaters. When dealing with commercial water heater repair, utilizing the correct 100108379 gasket prevents nuisance leaks, reduces heat loss at the element junction, and protects the tank's threaded connection from corrosion.
