Bomag 06550008 Reducing Nipple

The Bomag 06550008 Reducing Nipple is a genuine OEM fitting designed for Bomag tandem rollers spanning multiple generations and configurations, including the BW 90 AC-2, BW 90 AC-5, BW 100 AC-3, BW 100 AC-4, BW 100 ACM-5, BW 100 SCC-5, BW 115 AC-3, BW 115 AC-5, BW 120 AC-3, BW 120 AC-4, BW 125 AC-4, BW 131 ACW-2, BW 131 ACW-3, BW 131 ACW-5, BW 135 AC, BW 135 AD-5, BW 138 AC, BW 138 AC-5, BW 138 AD-5, BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2. Sourced directly from Bomag, this fitting carries the part number 06550008 and is manufactured to the same specifications as the original component. Choosing a genuine OEM part means the reducing nipple threads, taper, and sealing surfaces match the host system exactly — keeping fluid circuits leak-free and operating as intended.

Key Features

• Genuine OEM Thread and Taper Accuracy — machined to Bomag's exact thread pitch and seating geometry, ensuring a leak-free seal in hydraulic or fluid-circuit connections without the risk of cross-threading or pressure loss associated with imprecise fittings.
• Direct Drop-In Replacement — matches the original reducing nipple's port sizing and fitting type, so this part installs directly into the existing port without adapters or rework.
• Broad Tandem Roller Coverage — fits a wide range of Bomag tandem rollers including BW 90, BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, BW 138, BW 161, BW 164, and BW 202 series machines across AC, AD, ACW, ACM, AHD, and SCC variants.
• Maintains System Pressure Integrity — a correctly seated reducing nipple preserves the rated pressure differential between connected lines; a worn, cracked, or improperly sized nipple can introduce leaks that compromise hydraulic or fluid-system performance across the roller.

A reducing nipple is a threaded fitting that connects two ports or lines of different diameters within a machine's fluid circuit, stepping down from a larger bore to a smaller one while maintaining a sealed, pressure-rated junction. In tandem rollers, these fittings appear in hydraulic and fluid plumbing runs where line sizes change between components such as pumps, valves, and actuators. When a reducing nipple corrodes, strips, or develops a leak at its seating face, fluid loss and pressure drop follow — leading to sluggish or erratic system response and potential damage to downstream components if left unaddressed.
