Wacker Neuson 0031880 O-Ring

The Wacker Neuson is a genuine OEM O-Ring designed for the BS and DS series vibratory rammers, spanning two-cycle, four-cycle, oil-injected, and battery-assisted models including the BS50, BS60, BS70, DS70, and DS720. As a direct factory replacement, part is produced to the exact material and dimensional standards required for proper sealing in these machines. This O-Ring services an exceptionally wide range of rammer configurations, from compact 165mm shoe models through heavy-duty 330mm shoe variants. Confirming your machine's model number before ordering ensures you receive the correct sealing component for your specific unit.

Key Features

• Genuine OEM Sealing Material — Manufactured to Wacker Neuson's exact elastomer compound and cross-section specification, ensuring the compression and chemical resistance needed in a rammer's fuel and oil circuits.
• Direct Factory Replacement — Part number 0031880 installs in place of the original O-Ring with no trimming, stretching, or improvisation; the seat dimensions and durometer match the original groove geometry.
• Broad Rammer Series Coverage — Fits BS50, BS60, BS70, BS65-V, DS70, and DS720 vibratory rammers across two-cycle, four-cycle, oil-injected, high-altitude, and battery-assisted (AS50e, AS60e) variants.
• Leak Prevention at the Source — A correctly seated O-Ring maintains the pressure boundary in fuel, oil, or hydraulic passages; a cracked or flattened O-Ring leads to seepage, contamination, and accelerated wear of surrounding components.
• Fuel and Oil System Integrity — Replacing a degraded O-Ring during scheduled service or at first sign of weeping prevents fuel or oil migration into areas that can cause hard starting, rough running, or internal corrosion.

An O-Ring is a precision-molded loop of elastomeric material used to create a static or dynamic seal between two mating surfaces or threaded connections. In a vibratory rammer, O-Rings appear throughout the fuel system, oil lubrication circuit, and crankcase assemblies, where they prevent fluid leakage and maintain the correct internal pressure environment. When an O-Ring hardens, cracks, or deforms from heat cycling and vibration exposure, the seal fails — resulting in visible leaks, loss of lubrication, and potential damage to the components the fluid was protecting. Routine inspection and timely replacement of O-Rings like the Wacker Neuson 0031880 is one of the most cost-effective ways to preserve the service life of a rammer.
