The Multiquip 50290100 is a genuine OEM O-Ring 38X3 2G40 designed for RAMMAX walk-behind roller models including RW1404, RW1404MR, and RW1504HF. As a factory-sourced component, it is manufactured to the exact material grade and dimensional specification required for proper sealing performance in these machines. Confirmed fitment covers RW1404, RW1404MR (including units S/N 326075 and up), and RW1504HF up to S/N. When you need the right seal the first time, part number 50290100 delivers the confidence of OEM accuracy.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compound grade and cross-section spec required for hydraulic or fluid system integrity in RAMMAX roller applications.
- Exact Dimensional Fit — The 38x3mm profile seats correctly in its groove without stretching or compression mismatch, ensuring a leak-free installation from the first use.
- Confirmed Roller Fitment — Verified for RW1404, RW1404MR, and RW1504HF (up to S/N 1534188), including serial number breakpoints where applicable.
- Maintains Fluid System Integrity — A correctly seated O-ring prevents fluid bypass and pressure loss; a failed or worn seal can lead to leaks, contamination, and loss of hydraulic or lubrication function.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, so material composition, tolerancing, and part number traceability are fully aligned with the original machine build specification.
An O-ring is a circular sealing element used to prevent fluid or air from passing between mating surfaces in hydraulic, lubrication, or fluid-circuit connections. In walk-behind rollers like the RW1404 and RW1504HF series, O-rings appear throughout the hydraulic and drive systems wherever pressurized fluid must be contained within a joint or port. When an O-ring degrades, flattens, or cracks, it loses its ability to maintain a seal — resulting in fluid leaks, pressure drops, and potential damage to surrounding components. Replacing a worn O-ring promptly with the correct OEM part keeps the system operating at full capacity and prevents minor seal failures from escalating into larger repairs.
