Bomag 05542286 Reducing Union

The Bomag 05542286 Reducing Union is a genuine OEM component designed for a wide range of Bomag pavers, tandem rollers, single drum rollers, walk-behind rollers, refuse and landfill compactors, soil compactors, cold milling machines, recyclers/stabilizers, and reversible vibratory plates — including the BF 600, BF 700, BF 800, BF 900, and BF 300 paver families, BW-series tandem and single drum rollers, BC-series refuse/landfill and soil compactors, BM-series cold milling machines, MPH and RS recyclers/stabilizers, and the BPH 80/65 reversible vibratory plate. As a direct OEM replacement sourced from Bomag, part number 05542286 delivers the exact specifications needed to restore proper hydraulic or fluid line connections across this broad range of equipment. Fitment has been verified across all models listed, giving buyers confidence that this union installs correctly without modification.

Key Features

• Genuine OEM Fluid Line Integrity — manufactured to Bomag's original design tolerances, ensuring leak-free connections and correct flow characteristics specific to the hydraulic and fluid systems this reducing union serves
• Direct OEM Replacement — this reducing union matches the original fitting dimensions and thread specifications, allowing it to seat and seal correctly in the existing fluid line ports without rework
• Broad Verified Fitment — confirmed for Bomag BF-series pavers, BW tandem and single drum rollers, BC refuse/landfill and soil compactors, BM cold milling machines, MPH and RS recyclers/stabilizers, and the BPH 80/65 reversible vibratory plate, including multiple generation variants
• Maintains System Pressure — a correctly sized reducing union steps down line diameter while maintaining the pressure integrity the downstream circuit requires; a worn or improperly sized union risks pressure drop, leaks, and component damage
• Fuel and Hydraulic System Safety — used in fluid-carrying circuits, a properly torqued and correctly spec'd OEM union prevents uncontrolled leaks that could create fire risk or hydraulic failure in an operating machine

A reducing union connects two fluid lines of different diameters within a hydraulic, fuel, or coolant circuit, allowing flow to transition between line sizes while maintaining a sealed, pressure-rated joint. In Bomag equipment, this fitting plays a critical role in routing fluid through complex circuit layouts where line sizes must change between components. When a reducing union corrodes, strips, or fails to seal, the result is fluid leakage, pressure loss, and potential damage to downstream components — making timely replacement with a correctly specified OEM part essential to keeping the system operating as designed.
