Multiquip 91353671003 O-Ring 14MM Arai

The Multiquip 91353671003 is a genuine OEM O-Ring 14MM Arai designed for a wide range of Multiquip and Whiteman equipment including plate compactors, concrete mixers, walk-behind trowels, rollers, pumps, saws, and generators. As an authentic Multiquip part, the 91353671003 is manufactured to the same specification as the original component it replaces, ensuring a correct seal every time. This O-ring sees use across an extensive lineup including MVC82VH, MVH158GH, MVH208GH, MVH308GH, WM70S/P, MC94P/S, V305EH, AR13H, QP3TH, and many additional models — making it a high-utility service part worth keeping on the shelf.

Key Features

• Genuine OEM Sealing Material — Manufactured to the original compound and durometer specification for this 14MM O-ring application, delivering consistent compression and leak-free sealing across varied fluid types.
• Drop-In Fitment — Sized and profiled to seat correctly in the original groove geometry with no trimming or modification, maintaining proper seating depth and crush.
• Broad Equipment Coverage — A single part number that crosses plate compactors (MVC and MVH series), Whiteman mixers, walk-behind trowels, rollers, pumps, saws, and generators, making it a practical multi-machine service stock item.
• Leak Prevention Under Operating Pressure — A correctly installed O-ring maintains fluid and pressure integrity in hydraulic, fuel, and lubrication circuits; a worn or cracked ring leads to fluid weeping, pressure loss, and potential component damage.
• Fuel and Fluid System Compatibility — Appropriate for the sealing environments found across Multiquip equipment families, including fuel system and hydraulic interfaces where material compatibility is critical to safe operation.

An O-ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft or port, forming a pressure-tight barrier against fluid or gas leakage. When the joint is assembled and compressed, the ring deforms slightly to fill any microscopic gaps, preventing oil, fuel, hydraulic fluid, or water from passing through. Over time, heat cycling, chemical exposure, and mechanical compression cause the elastomer to harden, crack, or take a permanent set — at which point the seal fails and fluid begins to escape, leading to contamination, performance loss, or component damage. Replacing a worn O-ring with the correct OEM part restores the designed sealing performance and protects surrounding components from the effects of leakage.
