The Wacker Neuson 119410 O-Ring is a genuine OEM sealing component designed for the PT2, PT2A, PT2H, PT2V, PT3, PT3A, PT3H, and PT3V series self-priming centrifugal trash pumps. As a direct OEM replacement, this O-Ring is manufactured to the same material and dimensional standards as the original, ensuring a proper compression fit and leak-free seal within the pump assembly. It covers a wide range of 50mm/2-inch and 75mm/3-inch trash pump configurations across both engine-driven and bare pump variants. Keep a spare on hand — O-Rings are a routine service item and having the correct part number ready minimizes unplanned pump downtime.
Key Features
- Correct Material Grade for Sealing Service — Manufactured to OEM compound and durometer specifications, ensuring proper compression and long-lasting sealing performance in pump fluid passages.
- Drop-In Replacement Fit — Dimensionally identical to the original, so it seats correctly in the pump housing groove without stretching, trimming, or adjustment.
- Broad PT-Series Compatibility — Fits PT2, PT2A, PT2H, PT2V, PT3, PT3A, PT3H, and PT3V centrifugal trash pumps across multiple build series, covering both 50mm/2-inch and 75mm/3-inch discharge configurations.
- Leak Prevention at the Source — A correctly installed O-Ring maintains prime and prevents fluid bypass; a worn or damaged O-Ring causes the pump to lose prime, reducing flow output and risking dry-run damage to the pump.
- Genuine OEM Assurance — Supplied as a Wacker Neuson genuine OEM part, verified against part number 119410 for exact fitment across all listed PT-series models.
An O-Ring in a centrifugal trash pump serves as a static or dynamic seal between mating pump components — typically sealing the volute casing, inspection cover, or suction/discharge connections to prevent air ingestion and fluid leaks. When this seal is intact, the pump maintains the prime it needs to move water and slurry efficiently. A cracked, swollen, or flattened O-Ring breaks that seal, causing the pump to lose prime repeatedly, produce reduced flow, or fail to self-prime altogether. Replacing a worn O-Ring is one of the most cost-effective pump maintenance tasks available, and using the correct OEM part ensures the seal material is compatible with the fluids and pressures the PT-series pump is designed to handle.
