The Bomag 31781872 Seal is a genuine OEM replacement designed for BC 771 RB and BC 771 RS refuse and landfill compactors. Sourced directly from Bomag, this seal delivers an exact match to the original component it replaces, ensuring proper compression and sealing integrity without any guesswork on fitment. If you're servicing a BC 771 RB or BC 771 RS compactor, this is the correct part to restore the machine to full operating condition.
Key Features
- Genuine OEM Sealing Performance — manufactured to Bomag's original material and compression specifications, ensuring the seal conforms correctly to mating surfaces and maintains a leak-free barrier under the demanding conditions of landfill compaction work.
- Direct-Fit Replacement — engineered to match the original seal's geometry and dimensions, this seal installs into the same seat as the factory component with no rework or adaptation to surrounding hardware.
- Confirmed Fitment for BC 771 Series Compactors — compatible with the BC 771 RB and BC 771 RS refuse and landfill compactors, covering both variants in the BC 771 refuse compactor lineup.
- Protects Critical Components — a properly functioning seal prevents fluid intrusion and contamination in the assemblies it serves, protecting adjacent components from accelerated wear and keeping operating pressures stable.
- Verified Part Number Integrity — ordering by Bomag part number 31781872 confirms you're receiving the correct seal for your machine, eliminating the risk of receiving a mis-sized or incompatible substitute.
A seal serves as the barrier between moving or mating components, preventing fluid leakage and blocking contaminants from entering critical assemblies. On heavy refuse and landfill compactors like the BC 771 RB and BC 771 RS, seals are subject to extreme pressure, heat cycles, and exposure to debris — conditions that degrade seal material over time. When a seal fails, fluid loss, contamination, and accelerated wear to surrounding components follow quickly, making timely replacement essential to keeping the compactor productive on the landfill.
