The Multiquip 40022000 O Ring 5X9X2 2G40 is a genuine OEM sealing component designed for RAMMAX walk-behind rollers, including the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ). As a direct Multiquip OEM part, the 40022000 is manufactured to the exact material grade and dimensional tolerances required for proper sealing performance in these roller models. Sourcing the correct O-ring by 40022000 is critical — a mismatched size or compound can lead to fluid leaks, pressure loss, and accelerated wear on surrounding components. DHS Equipment supplies this part direct, so you can be confident you're getting the right fit the first time.
Key Features
- OEM-Specified Compound and Dimensions — The 5X9X2 sizing and 2G40 material designation are matched exactly to Multiquip's sealing requirements, ensuring correct compression and long-term integrity at the sealing surface.
- Drop-In Installation — Engineered to seat directly into the OEM groove without trimming or shimming, streamlining seal replacement on the RW1404MR and RW1504HF.
- Confirmed Fitment for RW1404MR and RW1504HF — Verified for RW1404MR units from S/N 326075 and up, and RW1504HF units up to S/N 1534188, so you can order with confidence.
- Leak Prevention at the Source — A properly seated O-ring maintains fluid containment and system pressure, keeping hydraulic or lubrication circuits functioning as designed in these RAMMAX rollers.
- Fluid System Integrity — Worn or undersized O-rings allow fluid bypass and contamination ingress; replacing with the correct 40022000 restores the sealed boundary and protects adjacent components.
An O-ring is a circular elastomeric seal seated in a machined groove to prevent fluid or gas from passing between mating surfaces or along a shaft. In walk-behind rollers like the RW1404MR and RW1504HF, O-rings are used throughout hydraulic circuits, bearing housings, and fluid reservoirs to maintain pressure and exclude contaminants. When an O-ring hardens, deforms, or tears, it loses its ability to form a complete seal — resulting in fluid leaks, pressure drop, and potential damage to pumps or drive components that depend on a closed system.
