Bomag 05548011 Double-Ended Union

The Bomag 05548011 Double-Ended Union is a genuine OEM fitting designed for an exceptionally wide range of Bomag equipment, including cold milling machines such as the BM 1000/35 and BM 2500/75, pavers including the BF 300 P, BF 600 P-2 S 500, and BF 800 C S600, single drum rollers such as the BW 213 D-5 and BW 226 DH-5, tandem rollers including the BW 120 AD-5 and BW 174 AP-4, pneumatic tyred rollers, reversible vibratory plates, recyclers and stabilizers, refuse and landfill compactors, soil compactors, and trench compactors. Sourced directly from Bomag, this fitting meets the same manufacturing standards as the component it replaces, ensuring a secure, leak-free hydraulic or fluid-line connection. With cross-fleet coverage spanning the BW, BM, BF, BC, BMP, BPR, MPH, and RS product lines, part number 05548011 is a versatile service item to have on hand for multi-machine fleets.

Key Features

• Genuine OEM Fluid-Line Integrity — manufactured to Bomag's own thread form and sealing specifications, so the union maintains full pressure ratings and leak-free performance in hydraulic and fluid-line circuits where an imprecise fitting can cause costly fluid loss
• Direct Swap Installation — matches the original port geometry and thread engagement of the replaced union, allowing straightforward removal and reinstallation without reworking the surrounding plumbing
• Exceptionally Broad Fleet Coverage — confirmed fitment across cold milling machines including the BM 500/15 and BM 2000/75, pavers including the BF 800 C S600 and BF 300 P, BW-series single drum, tandem, walk-behind, and pneumatic tyred rollers, BPR reversible vibratory plates, BC-series refuse, landfill, and soil compactors, MPH and RS recyclers and stabilizers, and BMP trench compactors
• Leak Prevention at the Connection Point — a failed or corroded double-ended union allows fluid to escape at the junction between two lines, starving downstream components of flow; this replacement restores a tight, rated connection and prevents fluid-starvation damage
• Fluid-System Safety Assurance — a weeping or failed union in a hydraulic or fuel circuit can create a fire or pressure-hazard risk on the machine; replacing a worn union with a genuine OEM part keeps the fluid system operating within its designed containment envelope

A double-ended union is a straight-through connector that joins two fluid lines end to end, maintaining a sealed, pressure-rated passage for hydraulic fluid, fuel, or coolant between them. It allows sections of tubing or hose to be disconnected and reconnected during service without disturbing the wider circuit. When a union corrodes, cracks, or develops thread damage, it can leak fluid at the joint, leading to pressure drop, fluid contamination, or potential fire risk — making timely replacement critical to keeping the machine's fluid systems safe and fully functional.
