Bomag 05542197 L-Union

The Bomag 05542197 L-Union is a genuine OEM hydraulic fitting designed for a broad range of Bomag heavy equipment, including cold milling machines such as the BM 500/15 and BM 2500/75, pavers including the BF 600 P-3 S 500 and BF 800 C-3 S 600, tandem rollers such as the BW 161 AD-4 and BW 202 AD-4, refuse and landfill compactors including the BC 772 RB and BC 972 RB, recyclers and stabilizers such as the MPH 122 and RS 500, and the BW 11 RH-5 pneumatic tyred roller. As a genuine Bomag OEM part, the part is manufactured to the exact specification of the original, ensuring proper sealing and secure line routing within the hydraulic system. This L-Union ships as a direct replacement for the original fitting, with no re-engineering or adaptation required to source a compatible substitute. Order with confidence knowing part number 05542197 is sourced directly through authorized Bomag supply channels.

Key Features

• Genuine OEM Sealing Integrity — manufactured to Bomag's original hydraulic fitting specification, delivering the correct thread form, angle, and material grade for leak-free performance under operating pressure
• Direct-Replacement Hydraulic Fitting — installs in place of the original L-Union with matching port connections, eliminating the need to source adapters or modify existing hydraulic lines
• Broad Bomag Equipment Coverage — fits cold milling machines including the BM 500/15 and BM 2500/75, pavers including the BF 600 P-3 S 500, tandem rollers including the BW 161 AD-4 and BW 202 AD-4, refuse compactors including the BC 772 RB, recyclers and stabilizers including the MPH 122 and RS 500, and the BW 11 RH-5 pneumatic tyred roller
• Hydraulic System Reliability — a correctly seated L-Union maintains system pressure and proper fluid routing; a failed or leaking fitting causes pressure loss, contamination risk, and potential damage to downstream hydraulic components
• Leak-Free Hydraulic Safety — hydraulic fluid leaks at fittings create slip hazards and fire risks on operating equipment; replacing a damaged union with the correct OEM part restores a safe, fully sealed hydraulic circuit

An L-Union is an angled hydraulic fitting — typically formed at 90 degrees — used to connect two hydraulic lines or hoses where a straight connection is not practical due to space constraints or routing requirements. It allows fluid to flow through a controlled directional change while maintaining a sealed, pressure-rated connection. When an L-Union cracks, corrodes, or develops a thread failure, the resulting leak reduces hydraulic pressure throughout the circuit, which can impair the performance of hydraulic actuators, motors, or steering systems and may lead to complete loss of function in affected systems if left unaddressed.
