The Bomag 05559583 Double Nipple is a genuine OEM fitting designed for Bomag BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers. Sourced directly from Bomag, this fitting carries the same specifications as the original component installed at the factory. This Double Nipple is an exact-match replacement that threads directly into the existing hydraulic or fluid line connections on supported machines, ensuring a leak-free, properly sealed joint. If you're servicing a covered tandem roller, verifying part number 05559583 against your machine's parts diagram confirms you're ordering the right component.
Key Features
- Genuine OEM Threaded Fittings — manufactured to Bomag's own specifications, ensuring correct thread pitch, shank length, and material grade for a dependable, pressure-rated connection
- Direct Thread-In Replacement — installs straight into the existing ports on covered tandem rollers with no rework or adaptation to mating lines or fittings
- Broad Tandem Roller Coverage — fits the BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers, spanning multiple variants in the series
- Leak-Free Fluid Circuit Integrity — a correctly fitted double nipple maintains sealed hydraulic or fluid line connections; a worn, cross-threaded, or incorrect fitting risks fluid loss and pressure drop that can impair drum drive or steering performance
- Verified Bomag Part Number — ordering by part number 05559583 eliminates guesswork and confirms the fitting matches the original specification for your machine
A double nipple is a short, externally threaded fitting — male threads on both ends — used to join two internally threaded ports or fittings together in a fluid or hydraulic circuit. On tandem rollers like the BW-series machines this part is designed for, these fittings appear throughout the hydraulic, lubrication, and water-spray systems wherever two lines or components must connect end-to-end. When a double nipple corrodes, strips, or develops thread damage, it can cause fluid leaks that compromise system pressure, lead to contamination, or result in unplanned downtime. Replacing it with an OEM-spec component restores a fully sealed connection and protects the integrity of the surrounding circuit.
