Multiquip 6505510310 Seal Ring DCA-400SPK SA6D140E-2

The Multiquip 6505510310 Seal Ring DCA-400SPK SA6D140E-2 is a genuine OEM seal ring designed for the DCA400SPK ultra-silent diesel generator. As a direct Multiquip OEM component, this seal ring is manufactured to the exact material and dimensional standards required by the SA6D140E-2 engine platform found in the DCA400SPK series. Sourced through DHS Equipment, you can be confident you are receiving an authentic Multiquip part with the correct specification for this application. Verify your model and engine configuration against part number 6505510310 before ordering to ensure a correct match.

Key Features

• OEM-Grade Sealing Material — Manufactured to the precise compound and compression specifications required by the SA6D140E-2 engine, ensuring proper sealing integrity under operating temperatures and pressures.
• Direct OEM Replacement — Engineered to seat correctly in the designated bore or mating surface of the SA6D140E-2 engine without rework or modification to surrounding components.
• Confirmed Fitment for DCA400SPK — Specifically matched to the DCA400SPK ultra-silent diesel generator series, taking the guesswork out of parts sourcing for this platform.
• Protects Engine from Fluid Loss and Contamination — A correctly functioning seal ring prevents oil or coolant bypass between mating surfaces; a worn or damaged seal can lead to fluid loss, overheating, or internal engine contamination.
• Genuine Multiquip OEM Part — Supplied under part number 6505510310 directly through the Multiquip OEM supply chain, ensuring traceability and correct application engineering.

A seal ring is a precision-engineered component used to create a fluid-tight barrier between two mating engine surfaces, such as a liner, housing, or fluid passage joint. In the SA6D140E-2 diesel engine, seal rings prevent the migration of engine oil or coolant across critical interfaces, maintaining correct fluid pressure and preventing cross-contamination. When a seal ring degrades, hardens, or takes a compression set over time, it loses its ability to conform to mating surfaces, allowing fluid bypass that can compromise lubrication, cause overheating, or result in progressive internal engine damage if not addressed promptly.
