Coberta de la bomba Sta-Rite — 5MPR / 5P4R (RC3185P)

Transparent pump lid for the Sta-Rite 5MPR / 5P4R pool pumps. Replace when the lid is cracked, crazed or has gone cloudy — a cracked lid is an obvious leak; a crazed lid is a stress-fracture waiting to blow under system pressure; a cloudy lid stops you from spotting a full strainer basket before the pump starts cavitating.

Genuine Sta-Rite / Pentair spec — matches the OEM thread pitch and o-ring groove exactly, so the tightening nut and lid o-ring you already have will install straight without any guesswork. Hand-tighten only during install: wrench torque cracks the plastic and negates the point of buying a new lid.
