Bomag 05814259 SAE Flange

The Bomag 05814259 SAE Flange is a genuine OEM hydraulic flange designed for a wide range of Bomag tandem rollers, single drum rollers, refuse/landfill compactors, soil compactors, and recycler/stabilizers. As a direct OEM replacement, this flange meets Bomag's original engineering standards, delivering the correct port geometry, bolt pattern, and sealing surface for a leak-free hydraulic connection. Compatible machines include BW-series tandem rollers such as the BW 144 AD-2, BW 164 AD, BW 174 AD, and BW 174 AP-4, single drum rollers including the BW 211 D-5, BW 212 D-5, BW 213 D-5, BW 214 D-5, BW 177 DH-4, and BW 179 DH-4, BC-series refuse/landfill compactors including the BC 472 RB, BC 672 RB, BC 772 RB, BC 972 RB, and BC 1172 RB, BC-series soil compactors including the BC 462 EB, BC 672 EB-2, BC 772 EB-2, and BC 473 EB-4, and RS-series recyclers/stabilizers including the RS 460 and RS 500. Verify your machine's model code against the fitment list to confirm compatibility before ordering.

Key Features

• Genuine OEM Hydraulic Integrity — Sourced directly from Bomag, this SAE flange is manufactured to the exact port dimensions and bolt-pattern tolerances required for a pressure-rated, leak-free hydraulic connection — no improvisation needed at the coupling point.
• SAE Standard Flange Interface — The SAE flange face and bolt pattern align directly with the original hydraulic circuit, ensuring a proper metal-to-metal seating surface and correct O-ring groove geometry for reliable sealing under operating pressure.
• Broad Cross-Family Fitment — Confirmed fit across Bomag tandem rollers, single drum rollers, refuse/landfill compactors, soil compactors, and recycler/stabilizers, including BW 174 AD-2, BW 213 D-5, BC 772 RB, BC 972 RB, RS 460, and RS 500, among many others.
• Hydraulic System Protection — A correctly seated SAE flange prevents hydraulic fluid leaks that can lead to pressure loss, component overheating, and contamination of the hydraulic circuit — keeping the machine's drive and vibration systems operating at full capacity.
• Correct Part Number for Confident Ordering — Part number 05814259 is the Bomag-assigned identifier for this SAE Flange, making cross-referencing against your parts manual straightforward and eliminating the risk of ordering a mismatched fitting.

An SAE flange is a standardized hydraulic fitting used to connect high-pressure hose assemblies or hydraulic lines to pumps, motors, valves, and manifolds within a machine's hydraulic system. The SAE flange design uses a flat face with an O-ring groove and a four-bolt clamping pattern to create a secure, high-pressure seal that resists vibration loosening — critical on compaction equipment subject to constant dynamic loading. When this flange is damaged, corroded, or improperly seated, the result is hydraulic fluid leakage, pressure drop across the circuit, and potential damage to downstream components including pumps and drive motors.
