The Bomag 05558761 Double Nipple is a genuine OEM fitting designed for Bomag BW-series tandem rollers and BM-series cold milling machines, including the BW 141 AD-4, BW 161 AD-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, and BM 500/15 and BM 600/15 cold milling machines. Sourced directly from Bomag, this double nipple matches the original component in thread spec, material, and dimensions — ensuring a secure, leak-free connection in the hydraulic or fluid circuit where it is installed. Verified under part number 05558761, this fitting covers an extensive range of AD-4, AC-4, AP-4, and ACP-4 tandem roller variants, making it a reliable go-to component for fleet operators running multiple Bomag machines.
Key Features
- Genuine OEM Thread Accuracy — manufactured to Bomag's exact thread profile and material spec, ensuring a pressure-rated, leak-free seal in fluid and hydraulic line connections
- Drop-In Replacement Fitting — matches the original double nipple on both ends for tool-free alignment and a straight installation into existing ports
- Broad Tandem Roller Coverage — fits BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, and additional AM, AC-4, AP-4, ACP-4, and ADH-4 variants, plus the BM 500/15 and BM 600/15 cold milling machines
- Fluid System Integrity — a correctly seated double nipple maintains consistent flow and pressure in the connected circuit; a failed or cross-threaded fitting risks fluid leaks, pressure loss, and component damage downstream
- Corrosion-Resistant Construction — built to withstand the temperature cycles and fluid exposure typical of continuous roller and milling machine operation
A double nipple is a short, externally threaded fitting with male threads on both ends, used to join two internally threaded ports or fittings in a fluid line. In Bomag tandem rollers and cold milling machines, these fittings appear in hydraulic and fluid circuits where two components must be connected end-to-end without a hose section. When a double nipple becomes damaged, corroded, or stripped, it can introduce leaks into the circuit, leading to pressure drop and potential damage to pumps, valves, or other connected components — making prompt replacement with a correctly specified part essential for maintaining system integrity.
