Key Features
- Genuine OEM Hydraulic Integrity — manufactured by Bomag to match the original banjo union's bore diameter, thread pitch, and sealing surfaces for leak-free hydraulic connections
- Direct Bolt-On Replacement — installs in the same hydraulic line port as the original, requiring no rework of fittings or line ends
- Broad Tandem Roller Coverage — fits BW 141, BW 151, BW 154, BW 161, BW 190, BW 202, BW 203, and BW 205 series tandem rollers, including AM, AC, ADH, ADO, and EU-Flex variants
- Sustained Hydraulic Flow — a correctly seated banjo union maintains consistent hydraulic pressure, supporting smooth drum drive and vibration system operation; a failed or cracked union causes pressure loss and erratic machine behavior
- Verified by Part Number 06550098 — ordering on the exact OEM part number confirms you receive the right fitting for your specific tandem roller configuration
A banjo union is a hollow, bolt-through hydraulic fitting that connects a hydraulic line to a port on a component such as a pump, motor, or valve block while allowing fluid to flow through the center of the bolt. The fitting's rounded banjo-shaped head seats against a machined surface with copper or aluminum sealing washers on each side, creating a leak-proof joint under pressure. When a banjo union cracks, strips its threads, or loses its sealing washers, the hydraulic circuit loses pressure — leading to weak or unresponsive drum drive, vibration system faults, or visible fluid leaks that require immediate attention to prevent further damage.
