Tapón de drenaje para bomba Sta-Rite con 2 juntas tóricas — 5P4R / SW5P4R (RU178920P)

Drain plug with 2× o-rings for the Sta-Rite 5JWP / 5P2R / S5P2R / 5P4R / SW5P4R pool pump volute. Used to drain the pump body for winterization or before any seal / impeller service — a stuck drain plug is a very common reason to have to break out heavier tools for what should be a 5-minute job.

The 2× o-rings are pre-fitted to the plug: one seals the plug body against the volute, one seals the internal air-bleed port. Direct OEM Sta-Rite / Pentair fit, no thread modifications needed. Hand-tighten only — over-torque strips the plastic thread on the volute and turns a €12 spare into a €200 volute replacement.
