Bomag 05545933 Union

The Bomag 05545933 Union is a genuine OEM fitting designed for an extensive range of Bomag equipment, including BW-series single drum rollers, BW-series tandem rollers, BF-series pavers, BM-series cold milling machines, BC-series refuse and landfill compactors, and MPH, RS, and BS recycler/stabilizer models. As an authentic Bomag replacement, this union is manufactured to the same standards as the original hardware, ensuring a correct, leak-free connection every time. Whether you are servicing a BW 213 D-5 single drum roller, a BF 600 P-3 S 500 paver, or a BM 1000/35 cold milling machine, part number 05545933 is the correct factory-specified union for the application. Sourcing the right union fitting is critical — an incorrect or worn union can compromise fluid routing, cause pressure loss, or lead to costly system failures in the field.

Key Features

• Genuine OEM Fluid-Line Integrity — Manufactured by Bomag to exact thread form and sealing specifications, this union maintains a secure, leak-free connection in hydraulic or fluid-routing circuits where a substandard fitting would risk pressure drop or contamination.
• Direct OEM Replacement — This union is designed to drop directly into the original fitting position, matching the thread pitch, body diameter, and port configuration of the factory-installed component.
• Broad Bomag Fleet Coverage — Compatible with a wide range of Bomag machines, including BW-series single drum and tandem rollers, BF-series pavers, BM-series cold milling machines, BC-series refuse/landfill compactors, and MPH, RS, and BS recycler/stabilizer models — covering multiple generations and variants across each family.
• System Pressure Preserved — A correctly functioning union maintains designed flow rates and operating pressures in the fluid circuit. A failed or cross-threaded union can cause fluid loss, erratic system behavior, and accelerated wear on downstream components.
• Correct Part for Fluid-System Safety — Fuel, hydraulic, and coolant unions are safety-relevant fittings. Using the genuine Bomag union ensures the connection meets the pressure ratings and material compatibility required for the fluid being routed.

A union is a threaded pipe or hose fitting that joins two sections of a fluid line — hydraulic, fuel, coolant, or similar — while allowing the connection to be opened and remade without disturbing the rest of the circuit. In heavy compaction and paving equipment, unions appear throughout fuel delivery, hydraulic control, and cooling systems, providing serviceable junction points wherever a line must be disconnected for maintenance or component replacement. When a union corrodes, cross-threads, or develops a compromised seating surface, it can no longer hold a reliable seal, resulting in fluid leakage, contamination, or pressure loss that degrades machine performance and creates a potential safety hazard.
