Bomag 05711754 Double-Ended Union

The Bomag 05711754 Double-Ended Union is a genuine OEM fitting designed for Bomag BC-series refuse/landfill compactors, BC-series soil compactors, MPH-series and RS 650 recyclers/stabilizers, and BM 2000/60 cold milling machines. Sourced directly from Bomag, this union matches the original specification to deliver a secure, leak-free hydraulic or fluid-line connection with no guesswork on compatibility. Covered models include the BC 571 RB, BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 672 RB-2, BC 672 EB-2, BC 772 RB, BC 772 RB-2, BC 772 RS, BC 772 RS-2, BC 772 EB-2, BC 972 RB, BC 972 RB-2, BC 1172 RB, BC 1172 RB-2, MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 650, BM 2000/60, and BM 2000/60-2.

Key Features

• Genuine OEM Fluid-Line Integrity — manufactured to Bomag's original thread form and sealing geometry, ensuring a pressure-rated, leak-free connection every time
• Direct Drop-In Replacement — matches the original port dimensions and union length so this fitting seats correctly without rework or adapters
• Broad Cross-Family Coverage — fits BC-series refuse/landfill and soil compactors, MPH-series and RS 650 recyclers/stabilizers, and BM 2000/60 cold milling machines across multiple production generations
• Protects Hydraulic System Performance — a failed or corroded union allows fluid loss and pressure drop that can starve downstream circuits; replacing it promptly keeps hydraulic output at design levels
• Verified by Part Number 05711754 — cross-reference this number against your machine's service manual or parts diagram before ordering to confirm the correct union for your application

A double-ended union is a straight-through pipe or hose fitting that joins two fluid lines end to end, creating a continuous, sealed passage for hydraulic fluid, coolant, or fuel. On heavy compactors, recyclers, and milling machines, these unions appear throughout the plumbing circuits wherever a removable, serviceable connection is needed between fixed lines. When a union corrodes, cracks, or its sealing faces wear, the joint weeps fluid — leading to pressure loss, contamination risk, and potential overheating of the hydraulic or cooling system. Replacing a worn union promptly with part number 05711754 restores a fully sealed circuit and prevents progressive damage to pumps, valves, and hoses downstream.
