PENTAIR GASKET SEAL PLATE (BB8)

The Pentair 357100Z Seal Plate O-Ring Gasket is a genuine factory-original OEM replacement sealing ring designed explicitly for Pentair’s high-performance pump lines [pentair.com]. This heavy-duty rubber elastomer gasket installs directly between the pump strainer housing pot (wet end) and the structural motor seal plate assembly. Replacing a flattened, stretched, or dry-rotted gasket instantly restores an airtight, high-pressure vacuum lock inside your pump, eliminating dangerous priming failures, external water puddles, and returning air bubbles.
