Bomag 05548018 Double-Ended Union

The Bomag 05548018 Double-Ended Union is a genuine OEM fitting designed for a wide range of Bomag cold milling machines, pavers, tandem rollers, single drum rollers, reversible vibratory plates, refuse/landfill compactors, and trench compactors. Sourced directly from Bomag, this union delivers an exact hydraulic or fluid-line connection that matches the original factory specification for each covered machine. Compatible models include BM 2000/60, BM 1200/30, BM 1300/30, BF 600 C HCE, BF 800 P S500, BW 120 AD-5, BW 100 AD-5, BPR 25/45 D-3, BC 1172 RB-3, BMP 8500, and many more across the Bomag lineup. Ordering by part number 05548018 ensures you receive the correct union for your specific machine configuration.

Key Features

• Genuine OEM Hydraulic Integrity — manufactured to Bomag's exact thread form, sealing surface, and pressure rating, so this union maintains leak-free fluid-line connections from day one
• Drop-In Replacement — threaded ends match the original port geometry on each covered machine, allowing direct installation without reworking fittings or lines
• Broad Cross-Family Coverage — fits Bomag cold milling machines including the BM 2000/60 and BM 1300/30, pavers including the BF 600 C HCE and BF 800 P S500, tandem rollers including the BW 120 AD-5 and BW 100 AD-5, reversible vibratory plates BPR 25/45-3 and BPR 25/45 D-3, refuse/landfill compactors, and BMP 8500 trench compactors
• Prevents Fluid Loss and Line Contamination — a correctly seated double-ended union keeps hydraulic or coolant circuits sealed; a worn or improperly sized union can introduce air, leak fluid, and degrade system pressure across the entire circuit
• Pressure-System Safety — in high-pressure hydraulic circuits common to milling machines and heavy rollers, a fitting rated and tested to OEM standards reduces the risk of line failure under operating load

A double-ended union is a straight-through connector that joins two sections of pipe or tubing within a fluid circuit, allowing the line to be separated and rejoined without disturbing the surrounding plumbing. It relies on precision-machined seating surfaces at both ends to create a leak-free seal under system pressure. When a union becomes corroded, cross-threaded, or worn, it allows fluid to escape or air to enter the circuit, which can cause pressure drop, overheating, or loss of hydraulic function — making prompt replacement critical to keeping the machine operational.
