The Multiquip 62166 O Ring 164Mmx3Mm Buna is a genuine OEM sealing component designed for Multiquip RAMMAX walk-behind and ride-on rollers, including the RW1404, RW1404MR, RW1403HF, RW1504HF, RW1810, RW3010, and P33/24 series. As a direct OEM part, 62166 meets the original engineering specification for material compound and dimensional tolerancing, ensuring a correct compression seal on reassembly. Sourced directly through authorized Multiquip supply channels, this O ring is backed by the confidence of genuine OEM provenance and is available through DHS Equipment for fast fulfillment.
Key Features
- Buna-N Compound Seal Integrity — Buna (nitrile) rubber construction provides strong resistance to hydraulic fluids and lubricants, maintaining a reliable seal under the operating pressures typical of roller hydraulic systems.
- Exact Dimensional Specification — At 164mm x 3mm, this O ring matches the original groove geometry precisely, allowing correct compression and seating without modification to the housing or mating surface.
- Genuine OEM Part — Supplied as a genuine Multiquip OEM component, part 62166 is manufactured to the same standard as the original, with no substitution in material grade or cross-section profile.
- Broad Roller Family Coverage — Fits RW1403HF, RW1404, RW1404MR, RW1504HF, RW1810, RW3010, and P33/24 FR/FC/FCR series rollers, including serial-number-specific variants such as RW1404MR S/N 326075 and up and RW1504HF up to S/N 1534188.
- Prevents Fluid Loss and Contamination — A failed or worn O ring in a roller's hydraulic circuit can cause fluid seepage, pressure drop, and contamination ingress — replacing it at service intervals protects the integrity of the entire hydraulic system.
An O ring is a circular elastomeric seal seated in a machined groove between two mating components. Its purpose is to block the passage of fluids or gases by deforming under compression, creating a leak-free barrier. In roller hydraulic systems, O rings are used throughout the circuit — in valve bodies, cylinder ports, and pump fittings — where even a minor seal failure can lead to fluid loss, reduced hydraulic pressure, and loss of drive or vibration function. When an O ring degrades due to heat cycling, chemical exposure, or simple age, it loses elasticity and begins to leak, making timely replacement essential to maintaining full machine output.
