Bomag 05542293 Reducing Union

The Bomag 05542293 Reducing Union is a genuine OEM component designed for a wide range of Bomag pavers, single drum rollers, tandem rollers, pneumatic tyred rollers, cold milling machines, refuse and landfill compactors, soil compactors, and recycler/stabilizers — including the BF 300 P, BF 800 C S600, BW 213 D-5, BW 161 AD-5, BM 1000/35, BM 2500/75, MPH 122, and RS 500, among many others. As a genuine Bomag OEM part, this reducing union is produced to the same specifications as the original, ensuring a correct connection in the hydraulic or fluid circuit it serves. Sourced directly through authorized channels, part number 05542293 gives equipment owners confidence that they are installing an exact match for their machine's plumbing system.

Key Features

• Genuine OEM Fluid-Circuit Integrity — manufactured to Bomag's original specifications, maintaining the correct bore reduction ratio and thread standards for leak-free hydraulic or fluid line connections.
• Direct-Fit Replacement — threads and port sizing match the original fitting, allowing this reducing union to seat and seal without modification in the existing plumbing circuit.
• Broad Bomag Compatibility — fits an extensive range of Bomag equipment including BF-series pavers, BW-series single drum and tandem rollers, BM-series cold milling machines, BC-series refuse and soil compactors, and MPH/RS recycler/stabilizers.
• Sustained Flow Performance — a correctly sized and properly sealed reducing union maintains consistent fluid pressure and flow through the circuit; a failed or incorrectly sized union can cause pressure loss, leaks, or downstream component damage.
• Verified Part Number Fitment — ordering by Bomag part number 05542293 ensures you receive the exact union specified in the original equipment bill of materials, eliminating guesswork on thread pitch and port dimensions.

A reducing union is a hydraulic or fluid-line fitting that connects two lines of different diameters, allowing fluid to pass between them while stepping down the port size in a single inline fitting. In Bomag equipment, this type of union is used throughout the hydraulic, fuel, and cooling plumbing systems wherever a larger-diameter line must transition cleanly to a smaller one. When the union becomes damaged, corroded, or develops a thread leak, fluid pressure in that circuit drops, which can lead to sluggish or erratic machine operation and potential fluid loss — making prompt replacement with the correct OEM part essential to keeping the system running as designed.
