Bomag 05545943 Union

The Bomag 05545943 Union is a genuine OEM fitting component designed for Bomag BF 600-series pavers, BW-series tandem rollers, and BC EB-series soil compactors. As an authentic Bomag part, this union is manufactured to the same specifications as the original, ensuring a correct connection within the hydraulic or fluid circuit it serves. Compatible machines include BF 600 P HCE, BF 600 C HCE, BF 600 C HCG, BF 600 C HSG, BF 600 C HSE, BF 600 P HCG, BF 600 P HSE, BF 600 C-E, BF 600 C-G, BF 600C HCE, BF 600C HSE pavers, BW 90 AD, BW 80 AD-2, BW 90 AD-2, BW 100 AC-3, BW 100 ADM-2, BW 120 AC-3, BW 80 ADS, BW 90 AC-2, and BW 900-2 rollers, as well as BC 462 EB, BC 672 EB-2, BC 772 EB-2, and BC 772 EB-4 soil compactors. Sourcing a verified OEM union by part number 05545943 eliminates guesswork and keeps your machine operating to specification.

Key Features

• OEM-Grade Sealing Integrity — manufactured to Bomag's original connection tolerances, this union maintains a leak-free junction within the fluid circuit, preventing pressure loss or contamination that a worn or poorly matched fitting would cause.
• Direct-Fit Replacement — matches the original thread form, port dimensions, and seating geometry so this union installs into the existing connection point without rework or adaptation.
• Broad Equipment Coverage — fits Bomag BF 600-series pavers, BW-series tandem rollers including the BW 100 AC-3 and BW 120 AC-3, BW 900-2 walk-behind roller, and BC EB-series soil compactors across multiple build generations.
• Consistent Flow Path — a correctly seated union keeps internal passage geometry intact, sustaining the designed flow rate and pressure to the downstream components it supplies.
• Genuine Bomag OEM Part — supplied as an authentic Bomag component under part number 05545943, backed by OEM sourcing through DHS Equipment for accurate part identification.

A union is a threaded or compression fitting that joins two sections of a fluid line — hydraulic, fuel, or coolant — while allowing the connection to be separated for service without disturbing the rest of the circuit. It maintains a sealed, pressure-rated joint that keeps fluid moving efficiently between system components. When a union fails, cracks, or develops a poor seat, fluid can leak at the joint, leading to pressure drop, contamination, or system shutdown — making timely replacement critical to sustained machine performance.
