The Multiquip 50499800 O-Ring 26.7x1.78 2G40 is a genuine OEM sealing component designed for RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ) RAMMAX walk-behind rollers. As a direct OEM replacement, part 50499800 is manufactured to the exact material grade, durometer, and dimensional tolerances specified for these machines — ensuring a correct, leak-free seat every time. Sourcing the correct O-ring by 50499800 is critical on hydraulic and fluid-circuit applications, where even a minor dimensional mismatch can cause sealing failure. DHS Equipment supplies this Multiquip OEM part to keep your RAMMAX roller operating at full capacity with zero compromise on sealing integrity.
Key Features
- OEM-Grade Elastomer Compound — Manufactured to the exact material specification for this sealing application, delivering the correct compression set and chemical resistance for the fluids used in RAMMAX roller systems.
- Dimensionally Exact at 26.7x1.78mm — Precise cross-section and inner diameter match the seating groove geometry on compatible roller components, allowing the O-ring to seat and compress correctly without shimming or adjustment.
- Confirmed Fitment for RAMMAX Rollers — Verified for RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N 1534188); always confirm your serial number range before ordering.
- Prevents Fluid Leaks at Critical Joints — A correctly sized and properly rated O-ring maintains fluid containment at hydraulic or lubrication interfaces; a worn or improperly sized ring leads to weeping seals, fluid loss, and eventual component damage.
- Genuine Multiquip OEM Part — Supplied under Multiquip part number 50499800, sourced directly through authorized distribution channels for full traceability and confidence in part authenticity.
An O-ring is a precision sealing element used to prevent fluid or air from passing between mating surfaces at joints, ports, and fittings throughout a machine's hydraulic, lubrication, or fluid systems. In walk-behind rollers like the RW1404MR and RW1504HF, O-rings are found at hydraulic connections and internal sealing points where maintaining pressure and preventing contamination is essential to drum drive and steering performance. When an O-ring deteriorates, hardens, or is installed with incorrect dimensions, the resulting leak can cause hydraulic pressure loss, fluid contamination, or accelerated wear on surrounding components — making exact-spec replacement critical.
