The Multiquip 40085001 Injection Seal 2G40 is a genuine OEM seal designed for RAMMAX walk-behind rollers, including the RW1404, RW1404MR, and RW1504HF series. As a direct Multiquip OEM component, the 40085001 is manufactured to the exact material grade and dimensional tolerances required for proper sealing performance in the hydraulic or fluid injection circuit. Fitment covers RW1404MR units at S/N 326075 and up, RW1504HF units up to S/N, and standard RW1404 models. Sourcing the correct OEM seal ensures the injection system operates as designed and prevents premature fluid loss or contamination.
Key Features
- OEM-Grade Seal Material — Manufactured to Multiquip's original compound and hardness specifications, delivering the compression resistance and fluid compatibility this injection circuit demands.
- Drop-In Replacement — Matches the original 40085001 profile and dimensions exactly, seating correctly without modification to housings or adjacent components.
- Confirmed Fitment — Verified for RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Prevents Fluid Loss — A correctly seated injection seal maintains system pressure and keeps fluid contained; a degraded or improperly sized seal leads to leaks, contamination, and loss of compaction performance.
- Genuine Multiquip Part — Supplied as an authentic OEM component, traceable to Multiquip's parts program and backed by DHS Equipment's parts expertise.
The injection seal in a RAMMAX roller forms a critical fluid-tight barrier within the machine's injection or hydraulic circuit, preventing internal or external leakage between mating components. When this seal degrades through heat cycling, wear, or age, fluid escapes the circuit, leading to pressure loss and inconsistent drum or drive behavior. Replacing the 40085001 Injection Seal 2G40 with a genuine OEM part restores the sealed integrity of the system and keeps the roller performing to specification on the compaction pass.
