The Multiquip 50310500 O-Ring 41X1,78 2G40 is a genuine OEM sealing component designed for RAMMAX walk-behind roller models including RW1404, RW1404MR, and RW1504HF. As a direct OEM replacement, this o-ring is produced to the exact material grade and dimensional specification required by the original equipment design. Fitment covers RW1404MR units from S/N 326075 and up, RW1504HF units up to S/N, and all RW1404 and RW1404MR configurations. Sourcing the correct part number 50310500 ensures the seal performs as intended without improvised substitution.
Key Features
- OEM-Matched Sealing Material — Manufactured to the precise compound grade and 41x1.78mm dimensional spec called out in the original equipment design, ensuring correct compression and fluid compatibility.
- Drop-In Replacement — Profiles match the original groove geometry on supported roller assemblies, seating correctly without reworking surrounding components.
- Confirmed Fitment — Verified for RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind roller models.
- Leak Prevention at the Source — A correctly seated o-ring of this specification maintains hydraulic or fluid system integrity; a worn or improperly sized seal leads to fluid weeping, pressure loss, and accelerated wear on adjacent components.
- Genuine Multiquip OEM Part — Supplied as a genuine OEM component, backed by Multiquip's parts program and sold through DHS Equipment as an authorized distributor.
An o-ring is a precision-molded loop seal used to prevent fluid or pressure from escaping between two joined surfaces or along a shaft. In roller hydraulic and drive systems, o-rings maintain the integrity of fluid passages — when one degrades, cracks, or takes a set from heat and age, it allows fluid to bypass the seal, resulting in pressure drop, external leaking, or contamination of adjacent systems. Replacing a worn o-ring with the correct OEM specification part — the right diameter and cross-section for the groove — is essential to restoring a proper, lasting seal rather than introducing a repeat failure point.
