Bomag 05542295 Reducing Union

The Bomag 05542295 Reducing Union is a genuine OEM component designed for a wide range of Bomag pavers, single drum rollers, tandem rollers, cold milling machines, and recycler/stabilizers — including BF 600 and BF 800 series pavers, BW 213 and BW 177 series single drum rollers, BM 500/15, BM 600/15, BM 1200/30, BM 2000/75, and BM 2500/75 cold milling machines, and MPH 121, MPH 122, RS 460, RS 500, and RS 650 recycler/stabilizers. As a direct OEM replacement, this reducing union is manufactured to the exact specification of the original part it replaces, ensuring a correct hydraulic or fluid-line connection with no rework required. Sourced directly from Bomag, part number 05542295 is the right choice when you need a part that fits the first time and holds up through demanding production cycles.

Key Features

• Genuine OEM Fluid-Line Integrity — manufactured to Bomag's original pressure and thread specifications, maintaining proper flow rate and sealing performance across every connected system
• Direct-Swap Replacement — matches the original port sizing and thread form so this reducing union installs directly into the existing fitting seat without additional adapters or machining
• Broad Cross-Family Fitment — covers BF-series pavers, BW-series single drum and tandem rollers, BM-series cold milling machines, and MPH/RS/BS recycler/stabilizers, including models such as BF 600 P HCE, BW 213 DH-4, BM 2000/75, and MPH 122
• Leak-Free Hydraulic Connection — a correctly seated reducing union prevents fluid loss, pressure drop, and contamination that can cause erratic system behavior or component damage downstream

A reducing union is a threaded fitting that connects two hydraulic or fluid lines of different diameters, allowing fluid to transition between line sizes while maintaining a sealed, pressure-rated path. In heavy equipment like Bomag pavers, rollers, and milling machines, these unions appear throughout hydraulic circuits, fuel systems, and coolant plumbing wherever a line size change is needed. When a reducing union fails — through thread damage, cracking, or seal deterioration — it causes fluid leaks that rob pressure from the circuit, introduce air or contaminants, and can escalate into broader system damage if left unaddressed. Replacing a worn or damaged union promptly with the correct OEM part restores system integrity and keeps the machine operating within its designed pressure parameters.
