The Wacker Neuson is a genuine OEM O-Ring designed for a wide range of Wacker Neuson equipment including the HSH350 hydronic surface heater, PT2H and PT3H centrifugal trash pumps, RD7 series tandem rollers, DS70 vibratory rammer, and E1100 ground heater. As a factory-sourced component, it is manufactured to the exact material grade and dimensional tolerances required by Wacker Neuson engineering. This O-Ring ensures a proper fluid-tight seal in the systems where it is installed, helping maintain correct operating pressure and preventing leaks across these diverse machine families. Verify your model and machine number against the fitment list before ordering to ensure a direct match.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's specified compound and durometer rating, ensuring correct compression and long-term sealing integrity in fluid and pressure systems.
- Direct-Fit Replacement — Dimensioned to seat precisely in the original groove or port, allowing straightforward installation without reworking mating surfaces or hardware.
- Broad Fitment Coverage — Compatible across multiple Wacker Neuson families including HSH350 hydronic heaters, PT2H and PT3H trash pumps, RD7 series tandem rollers, DS70 rammers, and E1100 surface heaters.
- Leak Prevention Where It Counts — A correctly seated O-Ring maintains system pressure and prevents fluid bypass; a failed or degraded seal can cause pressure loss, fluid leaks, or pump and heater malfunction.
- Fuel and Fluid System Safety — In fuel and hydraulic circuit applications, an intact O-Ring prevents uncontrolled fluid escape, supporting safe and compliant machine operation.
An O-Ring is a circular elastomeric seal used to close the gap between two mating components — such as a port, fitting, housing, or pump body — preventing fluid, fuel, or air from escaping under pressure. In equipment like trash pumps and hydronic heaters, a functioning O-Ring keeps the system sealed so pressure and flow remain consistent; even a small leak at this seal can cause a noticeable drop in pump output or heater performance. When an O-Ring degrades, cracks, or is compressed beyond its service life, the result is typically visible leaking, pressure loss, or contamination of surrounding components — all of which signal that the seal needs immediate replacement.
