The Bomag 05903326 Filler Cap is a genuine OEM component designed for Bomag BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC pneumatic tyred rollers, and the BW 177 PDH 5 single drum roller. Sourced directly from Bomag, this filler cap matches the original in dimensions, thread pitch, and sealing characteristics — no guesswork on compatibility. If you're servicing any of the covered machines, part number 05903326 is the correct OEM replacement to specify.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original specifications, ensuring the cap seats and seals exactly as the factory-installed unit did, preventing contamination ingress and fluid loss
- Direct Drop-In Replacement — matches original thread pitch, diameter, and retention design for a straightforward swap during routine service or fluid-system maintenance
- Broad Bomag Roller Coverage — fits BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, and BW 27 RH-4i BC pneumatic tyred rollers, as well as the BW 177 PDH 5 single drum roller
- Contamination Protection — a properly fitted cap keeps dirt, debris, and moisture out of the fluid system, protecting internal components from premature wear and fluid degradation
- Fluid System Safety — a cracked, stripped, or missing filler cap can allow hazardous fluid spillage and system pressure loss; replacing it promptly with a genuine OEM part maintains safe operating conditions
A filler cap seals the fill port on a fluid reservoir — whether hydraulic, engine oil, or coolant — keeping the system closed and free from contamination during operation. When the cap is damaged, missing, or no longer sealing correctly, outside debris and moisture can enter the fluid circuit, accelerating wear on pumps, seals, and other internal components. Replacing a worn or failed filler cap with the correct OEM part is a straightforward but critical maintenance step that preserves fluid cleanliness and system integrity across the machine's service life.
