The Wacker Neuson O-Ring is a genuine OEM sealing component 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, and the DS70 vibratory rammer. As a direct factory replacement, this O-Ring is manufactured to the exact material grade and dimensional tolerances required by the original design. It installs in place of the worn or failed seal with no alteration needed to mating components. Confirming your machine's model number against the fitment list before ordering ensures you receive the correct seal for your application.
Key Features
- Exact Material and Dimensional Specification — Manufactured to OEM compression and elastomer standards, ensuring a consistent, leak-free seal across every application it covers.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this O-Ring carries the same quality assurance as the seal installed at the factory.
- Broad Cross-Family Fitment — Confirmed for the HSH350 Hydronic Surface Heater, PT2H and PT3H trash pumps, RD7H and RD7H-ES tandem rollers, DS70 vibratory rammer, and E1100 ground heater series.
- Preserves Fluid and Pressure Integrity — A correctly seated O-Ring maintains the pressure boundaries within pump housings, heater circuits, and hydraulic passages; a worn or cracked seal allows fluid loss that can lead to overheating or loss of pump prime.
- Drop-In Replacement — Profile and cross-section match the original groove dimensions, allowing the seal to seat properly without modification to the housing or mating surfaces.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces, preventing fluid or air from escaping at the joint. In equipment like trash pumps, heaters, and rollers, these seals are found throughout the hydraulic, coolant, and fluid-handling circuits, where even a small leak can cause a pressure drop, fluid contamination, or overheating. When an O-Ring deteriorates — through heat cycling, chemical exposure, or mechanical wear — it loses its ability to compress and conform to the mating surfaces, allowing leaks to develop. Replacing a worn O-Ring promptly restores the sealed circuit to its correct operating condition and prevents secondary damage to surrounding components.
