The Wacker Neuson 30308 O-Ring is a genuine OEM sealing component designed for the PT2 series 50mm/2in centrifugal trash pumps, including the PT2Y, PT2A, PT2B, PT2R, and PTK2 models. Sourced directly from Wacker Neuson, this O-Ring matches the exact material grade and dimensional spec of the original part — ensuring a proper seal without modification. It is the correct replacement for all listed PT2 family variants, including the engineless PTK2 pump unit.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's original compound and durometer spec, so the O-Ring compresses and seals exactly as intended for pump service conditions.
- Drop-In Seating — Sized to seat correctly in the original groove without stretching, pinching, or trimming — reinstallation follows the standard service procedure.
- Broad PT2 Family Coverage — A single part number covers the PT2Y, PT2A, PT2B, PT2R, and PTK2 50mm/2in centrifugal trash pump variants.
- Leak-Free Pump Operation — A correctly seated O-Ring maintains internal pressure and prevents fluid bypass; a worn or damaged O-Ring causes loss of prime, reduced discharge flow, and external leakage.
- Fluid Containment Integrity — In pump applications handling wastewater and debris-laden fluids, a sound O-Ring seal is essential to prevent uncontrolled leakage at mating surfaces.
An O-Ring is a loop-shaped elastomeric seal that sits in a machined groove between two mating surfaces or components. In a centrifugal trash pump like the PT2 series, O-Rings are used at critical junctions — such as pump housing interfaces, volute covers, and port connections — to prevent fluid from bypassing or leaking out of the pressurized circuit. When an O-Ring hardens, cracks, or is compressed beyond recovery, the seal fails, allowing air ingestion or fluid leakage that results in loss of prime and reduced pumping performance. Replacing a worn O-Ring promptly restores the pump's ability to maintain prime and deliver consistent discharge flow.
