The Multiquip 42435 is a genuine OEM Retardant Tank Cap with Lanyard designed for a wide range of Multiquip equipment including AR14H rollers, HTX6H and STX6H ride-on trowels, HTXG6DF trowels, V305EH and V305EK walk-behind rollers, MTX-i60 rammers, and MVCi60 plate compactors. As a direct OEM replacement, this cap is manufactured to the same specifications as the original, ensuring a secure, leak-free fit on the retardant tank without any fitment guesswork. The integrated lanyard keeps the cap tethered to the machine so it stays with the equipment during operation and servicing. Sourced directly through Multiquip's authorized parts network, 42435 is the correct replacement when the original cap is lost, damaged, or worn.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original cap specification, delivering the thread engagement and sealing compression needed to prevent retardant fluid leaks during operation.
- Integrated Lanyard Retention — Built-in lanyard keeps the cap secured to the machine, eliminating the risk of losing the cap on a busy jobsite or during fluid refills.
- Broad Cross-Family Fitment — A single OEM part covering AR14H rollers, HTX6H, STX6H, and HTXG6DF ride-on trowels, V305EH and V305EK walk-behind rollers, MTX-i60 rammers, and MVCi60 plate compactors.
- Correct Fluid Containment — A properly sealed retardant tank cap prevents evaporation and spillage of the retardant solution, keeping the water system primed and ready for consistent slab wetting.
- Direct OEM Replacement — Part number 42435 matches the original component exactly, threading directly onto the existing tank fitting with no adapters or modifications.
The retardant tank cap seals the water or chemical retardant reservoir found on plate compactors, trowels, rollers, and rammers equipped with a surface-wetting system. This system delivers a thin film of water or retardant solution to the work surface, preventing concrete or compacted material from sticking to the machine's base plate or blades. When the cap is cracked, missing, or no longer seals correctly, the tank can lose fluid through evaporation or spillage, starving the wetting system and leading to surface adhesion, premature wear on contact components, and messy cleanups. Keeping a properly sealed cap in place ensures the retardant system functions as intended throughout the workday.
