Bomag 05903629 Filler Cap

The Bomag 05903629 Filler Cap is a genuine OEM component designed for Bomag cold milling machines, including the BM1000/30-2, BM1200/30-2, BM1300/30-2, BM1300/30-T3, and BM1200/30-T3. Sourced directly from Bomag, this filler cap matches the original part in material, thread pitch, and sealing characteristics — ensuring a correct fit with no guesswork. It is the same part that left the factory, maintaining the integrity of the fluid system on your milling machine.

Key Features

• Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and thread specifications, this filler cap delivers the same fluid containment performance as the original, preventing contamination and leaks at the fill point
• Direct Drop-In Replacement — engineered to the original dimensions and thread pattern, this cap installs directly onto the filler neck of compatible Bomag cold milling machines without modification
• Broad Cold Milling Machine Coverage — fits the BM1000/30-2, BM1000 30-2, BM1200/30-2, BM1200/30-T3, BM1300/30-2, BM1300 30-2, and BM1300/30-T3 cold milling machines
• Contamination Prevention — a properly seated filler cap keeps debris, moisture, and foreign material out of the fluid system, protecting internal components from accelerated wear
• OEM Part Number Confidence — ordering by Bomag part number 05903629 ensures you receive the correct cap for your machine, eliminating the risk of sourcing a non-fitting substitute

A filler cap seals the fluid fill port on the machine, preventing dirt, water, and debris from entering the system during and after servicing. On a cold milling machine, keeping the fluid system free of contamination is critical — ingested particles can cause rapid wear to pumps, motors, and other precision components. A damaged, missing, or incorrectly fitting cap compromises that barrier, making timely replacement with the correct OEM part an important part of routine machine maintenance.
