Wacker Neuson 5000094934 O-Ring

The Wacker Neuson is a genuine OEM O-Ring designed for a wide range of Wacker Neuson equipment, including DPU reversible vibratory plate compactors, RD7 tandem rollers, PT2H and PT3H trash pumps, HSH350 hydronic surface heaters, DS70 diesel rammers, and DPS single-direction vibratory plates. Sourced directly from Wacker Neuson, this O-Ring meets the original equipment specification for proper sealing performance across every compatible application. With fitment spanning dozens of DPU models — from the DPU 2440H through the DPU6555 and DPU6275 families — as well as RD7H and RD7He series tandem rollers, this is a high-utility service part to keep on hand. Using the correct OEM part number ensures the seal profile, material grade, and compression characteristics match what was installed at the factory.

Key Features

• OEM-Matched Seal Profile — Manufactured to the original Wacker Neuson dimensional specification, ensuring the correct cross-section and durometer for consistent compression and leak-free sealing.
• Direct-Fit Installation — Seats into the original groove without reworking or resizing, covering hydraulic, fuel, and fluid circuit applications across multiple machine families.
• Broad Multi-Family Fitment — Confirmed for DPU reversible vibratory plates, RD7 and RD7H tandem rollers, PT2H and PT3H trash pumps, HSH350 hydronic surface heaters, DS70 diesel rammers, and DPS single-direction plates.
• Prevents Fluid Loss and Contamination — A correctly seated O-Ring maintains system pressure and keeps contaminants out of hydraulic or fluid circuits; a degraded seal leads to leaks, pressure loss, and accelerated internal wear.
• Critical Fluid-System Safety — In fuel and hydraulic applications, a failed O-Ring can create fire risk or sudden loss of hydraulic control; replacing with the correct OEM part maintains the integrity of these systems.

An O-Ring is a circular elastomeric seal used throughout construction equipment to prevent fluid or gas from escaping at joints, ports, fittings, and component interfaces. It works by compressing into a machined groove when components are assembled, creating a pressure-tight barrier in hydraulic lines, fuel systems, pump housings, and cooling circuits. When an O-Ring hardens, cracks, or takes a permanent set, it loses the ability to maintain that seal — resulting in leaks, pressure drop, or contamination ingress that can cause premature component failure if left unaddressed.
