Description
This O’ring for 2.5″ heads is primarily used as the base seal between the control head and the FRP Vessel. This critical component ensures a leak-proof connection, preventing water bypass during service and regeneration cycles.
Maintain the integrity of your water treatment system with this premium replacement base O-ring. Specifically engineered for 2.5-inch control heads, this seal provides the essential hermetic interface between the valve head and the fiberglass-reinforced plastic (FRP) vessel. It is a direct replacement part designed to stop leaks at the tank’s neck and ensure peak efficiency during backwash, brine draw, and fast rinse cycles.
