The Bomag 05903975 Reducing Fitting is a genuine OEM component designed for BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors. Sourced directly from Bomag, this fitting delivers the exact dimensions and thread specification required for a correct, leak-free hydraulic or fluid line connection on these machines. Contractors running BC-series refuse compactors can order with confidence knowing this part number matches the original component installed at the factory.
Key Features
- OEM-Matched Thread and Taper Geometry — manufactured to the precise bore reduction dimensions specified for the BC-series hydraulic or fluid system, ensuring a proper seal without improvised adapters
- Direct-Swap Replacement — engineered to connect into the existing line assembly the same way the original fitting does, with no reworking of adjacent fittings or lines
- Confirmed Fitment for BC-Series Refuse Compactors — compatible with BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors
- Leak Prevention at the Reduction Point — a correctly sized reducing fitting keeps fluid routed at the right pressure and flow rate; a worn, cracked, or mismatched fitting risks seepage, pressure drop, and system contamination
- Genuine Bomag OEM Part — supplied under Bomag part number 05903975, meeting the same material and dimensional standards as the original production component
A reducing fitting transitions a fluid or hydraulic line from one diameter to a smaller one, allowing different-sized components within the same system to connect without interruption in flow. On heavy refuse and landfill compactors like the BC 972 and BC 1172 series, these fittings are critical junctions in hydraulic circuits that power drive, steering, and compaction functions. When a reducing fitting cracks, corrodes, or develops a poor seal, fluid loss and pressure inconsistency can compromise system response and lead to more extensive damage downstream.
