Multiquip 6004111670 Ring O SA12V140-1 DCA-800SSK

The Multiquip 6004111670 is a genuine OEM Ring O SA12V140-1 DCA-800SSK designed for the DCA800SSK ultra-silent diesel generator. Sourced directly from Multiquip, this O-ring is an exact-match component that restores proper sealing integrity to the engine or fluid system it serves. Confirm your model code against the DCA800SSK before ordering to ensure a direct, correct-fit installation.

Key Features

• OEM-Grade Sealing Material — Manufactured to the same material compound and dimensional tolerances as the original, ensuring consistent compression and leak-free sealing under operating temperatures and pressures found in the DCA800SSK.
• Exact-Fit Replacement — Engineered to the original profile and cross-section, allowing direct installation into the designated groove or port without reworking the mating surface.
• Confirmed Fitment for DCA800SSK — Specifically validated for the DCA800SSK ultra-silent diesel generator; verify your model code prior to ordering.
• Prevents Fluid and Air Ingress — A correctly seated O-ring maintains system pressure and keeps contaminants out, protecting downstream components from wear and premature failure.
• Genuine Multiquip OEM Part — Supplied as original equipment, so you are replacing a worn or damaged seal with a component built to the same specification as what left the factory.

An O-ring is a looped sealing element seated in a machined groove to create a pressure-tight barrier between two mating surfaces or around a shaft or port. In a large diesel generator such as the DCA800SSK, O-rings are used throughout the engine, cooling, lubrication, and fuel systems to prevent leaks and maintain the pressure differentials required for proper operation. When an O-ring hardens, cracks, or becomes deformed, it loses its ability to seal, resulting in fluid seepage, pressure loss, or contamination ingress that can escalate into more significant mechanical damage if left unaddressed.
