Product details
The Waterway 805-0232 is the union o-ring for the 2-1/2 inch tail piece. It is the seal between the tail piece and its mating union half.
Where it goes
Unions let a pump, filter or valve be broken loose without cutting pipe, and the o-ring is what makes that joint watertight. It is listed among Waterway Crystal Water cartridge filter parts and the push pull DE valve parts, and it is the 2.5 inch size specifically.
Diagnosing a leak
A union that drips while the pump runs, or that draws air on the suction side, is almost always down to this seal. Rubber flattens, dries and picks up nicks from grit, and once it takes a set it will not seal again no matter how hard the collar is tightened. Overtightening a union to chase a leak usually cracks the collar, so change the o-ring instead. A light film of silicone lubricant rated for pool use helps it seat and makes the next disassembly easier.
