Multiquip GM17494 Seal Washer DCA85USJ

The Multiquip GM17494 Seal Washer DCA85USJ is a genuine OEM replacement designed for the DCA85USJ ultra-silent diesel powered generator. Sourced directly from Multiquip, this part meets the original engineering specifications for the DCA85USJ, ensuring a correct, secure installation without guesswork. Keeping fluid and pressure integrity intact is critical on a generator running demanding jobsite loads, and the part is the right part to do exactly that.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact material grade and compression specification required for the DCA85USJ, ensuring a proper fluid-tight seal every time.
• Direct Drop-In Replacement — Engineered to the original dimensional profile of the DCA85USJ, the GM17494 seats and torques correctly without rework or shimming.
• Confirmed Fitment for DCA85USJ — Verified for Multiquip DCA85USJ ultra-silent diesel powered generators, so you can order with confidence.
• Protects Critical Generator Components — A properly functioning seal washer prevents fluid migration and pressure loss that can lead to leaks, contamination, and accelerated wear on surrounding engine and generator components.
• Fuel and Fluid System Safety — In fuel or hydraulic system applications, a failed or degraded seal washer can create leak points that pose fire and operational hazards; replacing with a genuine part restores safe system integrity.

A seal washer creates a pressure-tight, leak-free joint between mating components — typically at threaded fittings, drain plugs, or fluid line connections. It works by deforming slightly under torque load to fill microscopic surface irregularities and prevent fluid from escaping past the joint. When a seal washer becomes compressed, cracked, or chemically degraded over time, it loses its ability to maintain that barrier, leading to fluid leaks, pressure loss, and potential contamination of surrounding components. Replacing the GM17494 at the correct service interval keeps the DCA85USJ generator operating cleanly and reliably.
