The Wacker Neuson 5100016445 is a genuine OEM O-Ring designed for WP and VP series single-direction vibratory plate compactors, including the WP1540A, WP1550A, VP1340A, VP1550A, and VP2050A. Sourced directly from Wacker Neuson, this O-Ring matches the original component specification for a drop-in replacement with no guesswork. It is compatible across a wide range of WP and VP model variants, covering both standard and walk-behind configurations used in soil, asphalt, and aggregate base compaction applications. Confirm your machine number against the fitment list to ensure the 5100016445 is the correct O-Ring for your unit before ordering.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's original compound and durometer spec, ensuring correct compression and sealing performance at the intended interface.
- Direct Swap Installation — Matches the original O-Ring profile and cross-section exactly, seating into the existing groove without modification to the surrounding components.
- Broad WP and VP Series Coverage — Fits WP1540A, WP1550A, VP1340A, VP1550A, and VP2050A vibratory plate compactors across multiple production variants and regional configurations.
- Prevents Fluid Intrusion and Leakage — A correctly seated O-Ring maintains internal pressure and keeps contaminants out; a worn or cracked O-Ring leads to fluid seepage, accelerated wear on adjacent components, and loss of system integrity.
- Fuel and Fluid System Integrity — On fuel or hydraulic circuit applications, a failed O-Ring creates a fire or fluid-contamination risk; replacing with the correct OEM part restores safe, sealed operation.
An O-Ring is a precision-molded elastomeric seal that sits in a machined groove to create a leak-free barrier between two mating surfaces or components. On vibratory plate compactors like the WP and VP series, O-Rings appear throughout the fuel system, exciter housing, and hydraulic or oil circuits, where they prevent fluid loss and stop external debris from entering critical assemblies. When an O-Ring degrades — through heat cycling, chemical exposure, or mechanical compression set — it loses its ability to seal, which can result in visible leaks, internal contamination, and damage to the surrounding components if left unaddressed.
