Bomag 05553339 Double-Ended Union

The Bomag 05553339 Double-Ended Union is a genuine OEM fitting designed for an extensive range of Bomag BW-series rollers and BM-series cold milling machines, including walk-behind and light rollers such as the BW 65 and BW 75 ADL, tandem rollers across generations including the BW 100, BW 120, BW 138, BW 151, BW 161, BW 174, BW 202, and BW 206 families, pneumatic tyred rollers including the BW 12 R, BW 24 RH, BW 25 RH, BW 27 RH, and BW 28 RH, and cold milling machines including the BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, and BM 1300/35. As a genuine Bomag OEM component, part number 05553339 is manufactured to the same standards as the original, ensuring a correct, leak-free connection every time. This double-ended union is a direct, drop-in replacement that restores proper fluid line integrity without additional adaptation.

Key Features

• Genuine OEM Fluid Integrity — Manufactured to Bomag's original specifications, this double-ended union maintains the sealed, pressure-rated connection required for dependable hydraulic or fluid line performance.
• Direct Drop-In Replacement — Threads and seat geometry match the original fitting exactly, allowing straightforward installation without reworking surrounding line connections.
• Broad Bomag Coverage — Fits walk-behind and light rollers, tandem rollers, pneumatic tyred rollers, and cold milling machines across multiple BW and BM model generations, including the BW 120, BW 161, BW 174, BM 500/15, and BM 1000/35, among many others.
• Leak-Free Connection — A correctly seated double-ended union prevents fluid loss that can lead to pressure drop, overheating, or system contamination — keeping hydraulic and fluid circuits performing as designed.
• Long Service Life — Built from materials selected for Bomag's operating environments, this union resists vibration-induced loosening and the thermal cycling common in compaction and milling applications.

A double-ended union is a threaded fitting used to join two fluid lines at a single connection point, allowing sections of hydraulic, fuel, or coolant plumbing to be coupled and decoupled without disturbing the rest of the system. It plays a critical role in maintaining a sealed, pressure-stable circuit — a failed or corroded union can cause fluid leaks that starve downstream components of flow, resulting in overheating, loss of drive or vibration function, or unplanned downtime. Replacing a worn union with a genuine Bomag part number 05553339 restores the original connection geometry and sealing performance across the full range of compatible BW and BM machines.
