Multiquip 42435 Retardant Tank Cap with Lanyard - OEM Replacement Part

This tethered cap secures the water tank on Multiquip ride-on rollers, preventing contamination and water loss during compaction operations. The integrated lanyard keeps the cap attached to the tank, eliminating the risk of loss during field operations when refilling the water system used for drum wetting and dust suppression.

On the AR14H roller, the water tank holds 34 gallons (130 liters) and supplies water to the sprinkler system that keeps material from adhering to the drums during asphalt and soil compaction work. The tethered design ensures the cap remains with the equipment even when removed for filling, which is critical for maintaining system cleanliness and preventing debris from entering the water pump and filter assembly. Regular inspection of the cap seal is recommended to maintain proper tank pressure and prevent leaks during transport and operation.
