The Bomag 05904012 Sealing Washer is a genuine OEM component designed for Bomag cold milling machines, including the BM1000/30-2, BM1000 30-2, BM1200 30-2, BM1300/30-2, BM1300 30-2, BM 1200/30, and BM 1300/30. Sourced directly from Bomag, this sealing washer matches the original part in material grade, dimensional tolerancing, and sealing performance — ensuring a correct, leak-free installation every time. When replacing worn or damaged sealing hardware on your cold milling machine, confirming an exact part number match like 05904012 is the fastest way to get back to work without guesswork.
Key Features
- OEM Sealing Integrity — manufactured to Bomag's original material and compression specifications, delivering the same fluid-tight seal as the factory-installed washer
- Direct Bolt-On Replacement — dimensionally identical to the original, this sealing washer seats and torques correctly without rework or shimming
- Broad Cold Milling Machine Coverage — fits the BM1000/30-2, BM1000 30-2, BM1200 30-2, BM1300/30-2, BM1300 30-2, BM 1200/30, and BM 1300/30 cold milling machines
- Leak Prevention at the Source — a failed or worn sealing washer allows fluid weepage at fastener or fitting joints; replacing it promptly protects surrounding components from contamination and corrosion
- Fluid System Safety — correct sealing at hydraulic or fuel connection points prevents hazardous leaks, keeping the machine and operator in compliance with safe operating conditions
A sealing washer creates a pressure-tight, leak-free joint at threaded fastener or fitting connections in hydraulic, fuel, or coolant circuits. It deforms slightly under torque load to fill microscopic surface irregularities between mating faces, preventing fluid from escaping around the connection point. When a sealing washer wears, deforms permanently, or is damaged during a service procedure, the joint can weep or leak — leading to fluid loss, system pressure drop, and potential contamination of the work area or machine components.
