The Multiquip 51659 O-Ring RW-700 1402 1403 is a genuine OEM seal designed for Multiquip RAMMAX walk-behind roller models including the RW1403HF, RW1404, RW1404MR, and RW1404MR units from S/N 326075 and up. As a factory-sourced component, it meets the exact dimensional and material standards set by Multiquip for these roller platforms. Sourced direct from Multiquip, this part carries the same specifications as the original, ensuring a proper seat and reliable seal on installation. DHS Equipment supplies this genuine OEM part to keep your roller running at full capability with the correct component every time.
Key Features
- Genuine OEM Sealing Material — Factory-spec elastomer compound engineered to hold compression and resist fluid degradation in RAMMAX roller hydraulic and fluid systems.
- Drop-In Dimensional Accuracy — Machined to the precise inner diameter, outer diameter, and cross-section required for correct groove seating on RW-series components — no trimming or adaptation needed.
- Confirmed Fitment for RW Roller Models — Verified for the RW1403HF, RW1404, RW1404MR, and RW1404MR (S/N 326075 and up) walk-behind roller platforms.
- Prevents Fluid Loss and System Pressure Drop — A worn or damaged O-ring allows hydraulic fluid or oil to bypass the seal, causing pressure loss, contamination, and potential component damage throughout the system.
- Fluid System Integrity — Proper sealing is critical on roller equipment where hydraulic pressure drives drum vibration and propulsion — a failed seal can compromise both compaction output and drive performance.
An O-ring is a loop-shaped seal that sits in a machined groove between two mating surfaces or around a shaft or port to prevent fluid from leaking past the joint. In walk-behind roller equipment like the RW1403HF and RW1404 series, O-rings are used throughout the hydraulic and fluid systems to maintain pressure and keep oil or hydraulic fluid contained within their intended circuits. When an O-ring hardens, cracks, or becomes compressed beyond its usable range, it loses its ability to seal, resulting in leaks, pressure loss, and potential damage to surrounding components — making timely replacement with the correct OEM part essential to maintaining system performance.
