The Wacker Neuson O-Ring 120.65 X 3.18 70 Sh is a genuine OEM seal designed for the BPS 2550A single direction vibratory plate. As a direct OEM replacement, is manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the correct elastomer grade and compression characteristics for this application. Sourced directly from Wacker Neuson, this seal slots in as a like-for-like replacement with no guesswork on sizing or durometer. Keep a spare on hand to minimize unplanned service time during maintenance intervals.
Key Features
- Correct Durometer and Compound: — Rated at 70 Shore hardness, matching the original seal specification for dependable compression and fluid retention in this application.
- Exact Dimensional Match: — Sized at 120.65 x 3.18 mm to seat flush in the original groove, eliminating the risk of pinching, rolling, or improper seating during installation.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, so the material formulation and cross-section profile match what left the factory originally.
- Leak Prevention at the Source: — A correctly seated O-Ring maintains internal pressure and keeps contaminants out, preventing fluid loss that can lead to accelerated wear or component damage in the vibratory system.
- Fits BPS 2550A Vibratory Plate: — Confirmed fitment for the BPS 2550A single direction vibratory plate, so you can order with confidence against your machine's model.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or around a moving component, creating a pressure-tight barrier against fluid or air leakage. On a vibratory plate compactor, O-Rings are critical to keeping hydraulic or lubricating fluid contained within the system — even minor seal degradation can result in seeping fluid, loss of operating pressure, and eventual damage to surrounding components. When an O-Ring hardens, cracks, or is compressed beyond its recovery range, it loses its ability to seal, making timely replacement essential to keeping the machine performing as intended.
