Key Features
- OEM-Grade Sealing Material — Produced to Multiquip's exact compound and durometer specifications, ensuring the ring compresses and seals correctly under operating pressure.
- Exact Dimensional Specification — 3-1/2 in. inner diameter by 3-3/4 in. outer diameter matches the groove geometry of the MQS-185, allowing the ring to seat flush without gaps or distortion.
- Confirmed MQS-185 Fitment — Verified genuine OEM replacement for the Multiquip MQS-185, eliminating guesswork when sourcing a sealing component for this machine.
- Leak Prevention Where It Counts — A correctly sized and properly seated O-ring maintains a fluid-tight barrier, preventing leaks that can lead to pressure loss, fluid contamination, or component damage over time.
- Fluid System Integrity — Using the correct OEM O-ring in hydraulic or fluid-carrying connections is critical; an undersized or incompatible ring can fail under pressure and compromise the entire fluid circuit.
An O-ring is a molded elastomeric seal that fits into a machined groove and compresses between two mating surfaces to prevent fluid or air from escaping. In hydraulic, fluid, or pneumatic systems, the O-ring acts as the primary barrier keeping pressurized media contained within the assembly. When an O-ring wears, hardens, or is damaged, the seal is lost — resulting in leaks, pressure drop, and potential damage to surrounding components. Replacing a failed O-ring promptly with the correct OEM part restores the integrity of the sealed connection and protects the broader system from secondary failures.
