The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the DPU 100-70 reversible vibratory plate compactor and PIR 35 pneumatic internal vibrators. As a direct Wacker Neuson OEM part, the is manufactured to the same tolerances and material specifications as the original, ensuring a proper seal at the correct compression rate for your application. This O-Ring fits multiple machine types across the Wacker Neuson lineup, making it a useful stocking item for operations running both compaction and concrete equipment. Always confirm your machine's model and serial number against the fitment data before ordering.
Key Features
- OEM Material Specification — Manufactured to Wacker Neuson's original compound and durometer spec, delivering the correct compression and sealing performance for hydraulic and pneumatic circuits where off-spec materials can cause premature leak points.
- Drop-In Replacement — Dimensioned to seat in the original groove without trimming or stretching, maintaining the correct cross-sectional profile for a proper static or dynamic seal.
- Cross-Family Fitment — Compatible with the DPU 100-70 reversible vibratory plate compactor (100 kN, 70 cm/28 in) and PIR 35 pneumatic internal vibrators (Ø 35 mm), covering two distinct Wacker Neuson machine families.
- Leak Prevention — A correctly installed O-Ring of the right compound maintains system pressure and keeps fluids or air contained; a degraded or incorrectly sized ring leads to fluid loss, pressure drop, and accelerated wear on surrounding components.
- Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000031397 carries the manufacturer's part number verification so you can order with confidence that the spec matches the original build.
An O-Ring is a continuous loop of elastomeric material that creates a pressure-tight seal between two mating surfaces, preventing fluid or air from escaping at joints, ports, or moving interfaces. In compaction equipment like the DPU 100-70, O-Rings are commonly used in hydraulic circuits and drive assemblies where maintaining system pressure is critical to consistent plate force and reversible travel function. In pneumatic internal vibrators like the PIR 35, they seal air passages that drive vibration output — a worn or cracked O-Ring in either application allows pressure to bleed off, reducing performance and potentially allowing contaminants to enter the system.
