Bomag 05542193 L-Union

The Bomag 05542193 L-Union is a genuine OEM hydraulic fitting designed for a wide range of Bomag pavers, cold milling machines, rollers, trench compactors, recyclers/stabilizers, and refuse/landfill compactors — including BF 600, BF 800, BF 900, BM 1000/35, BM 2000/75, BW 213, BW 216, and many more. Sourced directly from Bomag, this L-Union meets the same engineering standards as the original component installed at the factory. The correct fitting is critical in hydraulic circuits: an improperly specified union can cause fluid leaks, pressure loss, and component damage that sidelines your equipment. Part number 05542193 is the verified Bomag replacement to restore your hydraulic line routing to spec.

Key Features

• Genuine OEM Hydraulic Integrity — manufactured to Bomag's exact thread form, angle, and pressure rating, ensuring leak-free sealing in demanding hydraulic circuits across diverse machine types.
• Direct-Swap Installation — the L-Union connects to existing hydraulic line ports without rework, threading in at the correct angle to restore original line routing and flow path.
• Broad Bomag Fleet Coverage — fits pavers including the BF 300, BF 600, BF 700, BF 800, and BF 900 series; cold milling machines including the BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, BM 1300/35, BM 2000/60, BM 2000/75, BM 2200/75, and BM 2500/75; single drum, tandem, walk-behind, and pneumatic tyred rollers across numerous BW series; recyclers/stabilizers including MPH 121, MPH 122, MPH 125, MPH 600, RS 460, RS 500, RS 650, and BS 16000 Profi; refuse/landfill compactors including BC 462 RB, BC 472 RB, BC 472 RS, BC 473 RB-3, BC 473 RB-4, BC 473 RS-4, BC 672 RB-4, BC 772 RB-4, and BC 772 RS-4; soil compactors including BC 462 EB, BC 473 EB-3, BC 473 EB-4, and BC 772 EB-4; and trench compactors including BMP 851, BMP 8500, BMP 8500 Kohler, BMP 8500 Kubota, BW 650 T, BW 850 T, BW 850 TR, BW 1050 T, and BW 85 T.
• Pressure-Tight Angled Routing — the 90-degree union body redirects hydraulic lines cleanly in tight machine envelopes, maintaining full-flow capacity without restricting circuit pressure.
• Leak Prevention Protects Downstream Components — a worn or cracked L-Union allows hydraulic fluid loss that can starve pumps, overheat the system, and cause progressive damage to valves and actuators; replacing this fitting at first sign of seepage prevents cascading failures.

An L-Union is an angled hydraulic pipe fitting that joins two sections of hydraulic line at a fixed angle — typically 90 degrees — allowing fluid to be routed through tight spaces or around obstructions within the machine's frame or engine bay. It maintains a sealed, pressure-rated connection that keeps hydraulic fluid moving efficiently between system components such as pumps, valves, and cylinders. When an L-Union develops a leak, cracks, or damaged threads, system pressure drops and fluid contamination risks increase, which can trigger erratic behavior in steering, vibration, or drive systems depending on which circuit the fitting serves.
