The Multiquip 66-853217 Square Seal Ring 120.32x2.51 RW1800 is a genuine OEM seal ring designed for the RW-1800 RAMMAX walk-behind roller. Sourced directly from Multiquip, this part delivers the exact dimensional profile and material grade required to maintain a proper hydraulic or fluid seal within the roller's system. Confirmed fitment for the RW-1800 means you can install with confidence and get your machine back to work without guesswork.
Key Features
- Precision-Profiled Seal Geometry — Square cross-section design at 120.32x2.51 mm maintains consistent sealing contact across the full bore circumference, resisting pressure-driven distortion.
- Genuine OEM Material Grade — Manufactured to Multiquip's original compound specification, ensuring the correct compression set and chemical compatibility for the RW-1800's fluid system.
- Direct Drop-In Fitment — Engineered to the exact groove dimensions of the RW-1800 RAMMAX roller, seating cleanly without trimming, shimming, or modification.
- Confirmed Compatibility — Verified for the RW-1800 series walk-behind roller; part number 66-853217 cross-references directly to this application.
- Hydraulic Integrity Protection — A correctly seated seal ring prevents fluid bypass and pressure loss, keeping the roller's compaction force and drive system operating at full output.
A square seal ring acts as a static or dynamic sealing element within a hydraulic or fluid-carrying assembly. Unlike a standard O-ring, its flat-sided profile resists rolling and twisting under pressure, maintaining a stable seal even through repeated pressure cycles. When this seal wears, cracks, or takes a permanent set, fluid can bypass the sealing surface — resulting in pressure loss, external leakage, or degraded performance in the system it serves. Replacing it with the correct OEM-spec part restores the original sealing integrity and prevents secondary damage to surrounding components.
