The Bomag 05553862 Reducing Fitting is a genuine OEM component designed for Bomag BW 174, BW 184, and BW 170 series tandem rollers. Sourced directly from Bomag, this fitting delivers the exact thread form, taper, and port sizing required to maintain a leak-free hydraulic or fluid line connection on your machine. This reducing fitting is confirmed to fit a wide range of tandem roller variants, including the BW 174 AC, BW 174 AD, BW 174 AP, BW 180 AD, BW 184 AD, BW 184 AD-2 AM, BW 170 AD, BW 170 AD-2 AM, and related AM and generation-2 variants. When you order using part number 05553862, you can be confident you are receiving the correct Bomag-specified component for your machine.
Key Features
- Genuine OEM Thread and Port Accuracy — machined to Bomag's own specifications, ensuring the reducing fitting matches the exact thread pitch, port diameter, and sealing geometry of the original component
- Drop-In Hydraulic Line Replacement — connects directly to existing fittings and lines without reworking ports or adapting adjacent hardware, keeping your fluid system intact
- Broad Tandem Roller Coverage — fits BW 170, BW 174, BW 180, and BW 184 series tandem rollers across AC, AD, AP, ACP, and AM variants, including generation-2 models
- Leak-Free Fluid System Integrity — a correctly seated reducing fitting prevents fluid weeping at the transition point, protecting hydraulic pressure and preventing contamination of surrounding components
- Verified with Bomag Part Number 05553862 — cross-reference this number against your machine's service manual or parts diagram before ordering to confirm the right fit for your specific serial range
A reducing fitting is a threaded adapter that transitions a fluid line from one port size to another within a hydraulic or lubrication circuit. It allows different-diameter lines or components to connect securely without requiring custom fabrication or mismatched fittings. When a reducing fitting wears, cracks, or develops thread damage, the result is typically a fluid leak at the junction point, which can cause pressure loss in the hydraulic system, contamination of surrounding components, and eventual damage to pumps, motors, or cylinders downstream. Replacing a failed fitting promptly with the correct Bomag OEM part restores full system integrity and prevents secondary damage across your tandem roller's fluid circuits.
