51005000-Style Drain Plug Seal O-Ring – Replacement-Compatible for Pool & Spa Filter & Valve Assemblies

51005000 Style Drain Plug O Ring Replacement

This aftermarket drain plug o-ring is made to replace worn or cracked seals on pool and spa equipment. It sits around the drain plug and helps create a tight seal so water does not leak out during everyday use or when you drain the filter.

It is a simple part, but it plays a key role in keeping your system dry and safe. A fresh O-ring for the drain plug can help stop slow drips, protect nearby parts, and maintain pressure at the right level.
