Bomag 05542294 Reducing Union

The Bomag 05542294 Reducing Union is a genuine OEM component designed for a broad range of Bomag pavers, single drum rollers, tandem rollers, pneumatic tyred rollers, cold milling machines, refuse and landfill compactors, soil compactors, and recycler/stabilizers. Sourced directly from Bomag, this reducing union matches the original part in thread specification, material grade, and dimensional tolerances — ensuring a secure, leak-free connection in the hydraulic or fluid circuit where it is installed. Confirmed fitment spans equipment including BF 600-series pavers, BW 213 D-3 and BW 161 AD-series rollers, BC 601 through BC 1172 refuse and landfill compactors, BM 2000/75 and BM 2500/75 cold milling machines, and MPH 121, MPH 122, and MPH 600 recycler/stabilizers, among many others. When you need a direct OEM replacement with no guesswork on compatibility, part number 05542294 is the correct choice.

Key Features

• OEM Thread and Dimensional Accuracy — manufactured to Bomag's original specifications, this reducing union delivers the exact thread pitch, port sizing, and body dimensions required for a proper, pressure-rated connection
• Drop-In Hydraulic/Fluid Line Replacement — threads directly into the original port without modification, maintaining the correct flow path and seal interface between lines of differing diameter
• Wide Cross-Machine Compatibility — fits an extensive range of Bomag equipment including BF 600-series pavers, BW single drum and tandem rollers, BC refuse/landfill and soil compactors, BM cold milling machines, and MPH and RS recycler/stabilizers
• Leak-Free System Integrity — a correctly fitted reducing union sustains hydraulic or fluid system pressure; a worn, cracked, or incorrect union risks fluid loss, pressure drop, and potential damage to downstream components
• Genuine Bomag Part — supplied as an authentic OEM component, verified under part number 05542294, so you order with confidence and avoid fitment issues common with unverified alternatives

A reducing union is a threaded fitting used to connect two fluid or hydraulic lines of different port sizes within a single circuit. It steps down from a larger port to a smaller one, maintaining a sealed, continuous flow path between components such as pumps, valves, filters, and actuators. When a reducing union fails — through thread wear, cracking, or corrosion — it can allow fluid to escape under pressure, disrupting system operation, triggering pressure faults, and potentially causing damage to sensitive hydraulic components further along the circuit. Replacing a worn or leaking union promptly with the correct OEM part keeps the fluid system operating at its designed pressure and flow rate.
