Bomag 05559585 Double Nipple

The Bomag 05559585 Double Nipple is a genuine OEM fitting designed for Bomag BW-series tandem rollers. Sourced directly from Bomag, this component meets the exact specifications of the original part it replaces, ensuring a correct, leak-free connection in the hydraulic or fluid system. This double nipple fits an extensive range of BW tandem roller models, including the BW 100 AD-3, BW 115 AD-3, BW 120 AD-3, BW 131 AD-3, BW 141 AD-4, BW 151 AD-4 AM, BW 154 AD-4, BW 161 AD-4, BW 164 AD, BW 190 AD-4, BW 202 AD-4, and BW 203 AD-4 AM, among others across the BW tandem roller lineup.

Key Features

• Genuine OEM Fluid-System Integrity — manufactured to Bomag's original thread form and sealing tolerances, this double nipple maintains a pressure-tight connection without improvised adapters or sealants
• Direct Drop-In Replacement — matches the original fitting's thread pitch, diameter, and end configuration so it threads into existing ports and lines without rework
• Broad BW Tandem Roller Coverage — confirmed fit across a wide range of BW tandem rollers including the BW 120 AD-3, BW 164 AD-2, BW 190 AD-4 AM, BW 202 AHD-2, and BW 131 ACW-3, covering multiple generations of Bomag tandem roller equipment
• Leak Prevention Where It Counts — a failed or cross-threaded double nipple allows fluid loss that can compromise hydraulic pressure or cooling performance; this OEM fitting restores the sealed connection the system depends on
• Fuel and Hydraulic System Safety — correct thread engagement and rated sealing on fittings in pressurized or fuel-carrying lines reduces the risk of fluid leaks that could create fire or system-failure hazards

A double nipple is a short threaded connector with male threads on both ends, used to join two female-threaded ports or lines in a fluid system. On Bomag tandem rollers, fittings like this appear throughout hydraulic circuits, fuel lines, and cooling connections where two components must be joined end to end. When a double nipple corrodes, cracks, or strips its threads, it can allow fluid to escape under pressure — leading to system pressure loss, contamination, or fluid pooling on hot surfaces. Replacing it with the correct OEM part restores a secure, rated connection and keeps the fluid circuit operating as intended.
