Key Features
- Genuine OEM Rubber Compound — manufactured to Bomag's original material grade, maintaining the correct flexibility and compression resistance expected from a rubber elbow in this application
- Direct-Fit Replacement — molded to the original elbow profile for a secure, leak-free connection without adapter fittings or reworking of existing hose runs
- Broad Tandem Roller Coverage — fits the BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers across AC and AD variants
- Maintains Fluid Routing Integrity — a cracked or hardened rubber elbow allows coolant or air leaks that can lead to overheating or erratic system pressure; replacing it restores proper flow and sealing
- Verified Part Number Fit — ordering by Bomag part number 78080502 ensures you receive the correct elbow geometry for your machine, eliminating the guesswork of cross-referencing aftermarket catalogs
A rubber elbow is a flexible molded connector used to route coolant, air, or other fluid between rigid components — such as a radiator, air cleaner, or engine inlet — where a straight hose cannot make the turn. Its flexibility absorbs vibration and allows for slight misalignment between fittings, protecting the surrounding components from stress cracking. When a rubber elbow ages, it can harden, crack, or collapse internally, restricting flow or causing leaks that quickly affect engine temperature and system performance.
