Bomag 05548034 Double-Ended Union

The Bomag 05548034 Double-Ended Union is a genuine OEM fitting designed for a wide range of Bomag single drum rollers, tandem rollers, refuse and landfill compactors, soil compactors, and cold milling machines. As a direct OEM replacement, this union is manufactured to the exact specifications required for proper fluid line connections across the BW roller series, BC compactor series, and BM cold milling series. Verified fitment includes models such as the BW 211 D-5, BW 213 D-5, BW 174 AP-4, BC 772 RB, BC 672 EB-2, and BM 1000/35-2, among many others. When a double-ended union fails or leaks, it can compromise hydraulic or fluid system integrity across the machine — this genuine OEM part restores the connection to the original sealed standard.

Key Features

• Genuine OEM Fluid Line Integrity — manufactured to Bomag's original thread and bore specifications, ensuring leak-free connections in hydraulic and fluid systems where tolerance is critical
• Direct Replacement Fit — this union installs directly into the existing line ports with no reworking of fittings or line ends required, matching the original connector geometry exactly
• Broad Cross-Series Compatibility — fits BW single drum rollers (including BW 211 and BW 213 series), BW tandem rollers (including BW 154 and BW 174 series), BC refuse and landfill compactors (including BC 572 RB-2, BC 671 RB, BC 772 RB-4), BC soil compactors (BC 772 EB-2, BC 672 EB-2, BC 772 EB-4), and BM cold milling machines (BM 1000/35-2, BM1200/35-2)
• Leak Prevention Under Operating Pressure — a correctly seated double-ended union maintains sealed, pressurized fluid flow; a worn or damaged union risks fluid loss, pressure drop, and system failure that can sideline the machine
• Fluid System Safety — maintaining an intact union connection prevents uncontrolled fluid discharge, protecting both the operator and surrounding components from hydraulic fluid exposure under pressure

A double-ended union is a threaded inline fitting that joins two fluid or hydraulic lines end to end, creating a sealed, removable connection point within the circuit. It allows sections of piping or hose to be connected, disconnected, and reconnected cleanly during service without disturbing the surrounding plumbing. When this fitting corrodes, strips, or develops a leak, fluid pressure in the circuit drops and the machine's hydraulic or cooling system can be compromised — making prompt replacement essential to keeping the system operating correctly.
