Waterway 805-0112 Drain Plug O-Ring – Pump Housing Winterizing Plug Seal

The Waterway 805-0112 O-Ring is a genuine replacement seal designed for use with Waterway pump housing drain plugs. This small but critical component creates a watertight seal at the drain port, preventing leaks during normal operation and after winterization service.

Over time, drain plug O-rings can become brittle, flattened, or cracked due to chemical exposure and temperature changes. Replacing the O-ring helps restore a proper seal and protects your pump from air leaks and water loss.
