Multiquip 8970420280 Exhaust Pipe Gasket

The Multiquip 8970420280 is a genuine OEM Exhaust Pipe Gasket designed for DCA25 and DCA20SPXU2 series ultra-silent and super-silent diesel generators. As a direct OEM replacement, this gasket is manufactured to the same specifications as the original component, ensuring a proper seal at the exhaust pipe junction. It is confirmed to fit a wide range of DCA-series models including DCA25SSIU2, DCA25SSIU3, DCA25USI, DCA25USIXF, DCA25USI2XF, DCA25USI4CAN, DCA20SPXU2, DCA25ESI, TLG12SPX, and DCA25USI2, among others. Sourcing the correct OEM part number 8970420280 eliminates guesswork and ensures the replacement seats correctly the first time.

Key Features

• OEM Material Integrity — Manufactured to original heat and compression tolerances required for diesel generator exhaust systems, maintaining a gas-tight seal under sustained operating temperatures.
• Drop-In Exhaust Pipe Fit — Sized and profiled to match the original exhaust pipe flange on DCA-series generators, seating flush without trimming or shimming.
• Broad DCA-Series Compatibility — Fits DCA25SSIU2, DCA25USI, DCA25USI2XF, DCA25USI4CAN, DCA20SPXU2, DCA25ESI, TLG12SPX, and additional ultra-silent and super-silent generator variants.
• Exhaust Leak Prevention — A correctly sealed exhaust pipe joint prevents combustion gases from escaping into the enclosure, protecting both generator performance and safe operation in enclosed or noise-sensitive environments.
• Critical Safety Application — Exhaust integrity on enclosed ultra-silent generators is essential to prevent carbon monoxide buildup; replacing a failed or compressed gasket promptly is a critical maintenance step.

The exhaust pipe gasket forms a sealed joint between the engine's exhaust outlet and the exhaust pipe assembly, preventing hot combustion gases from escaping at the connection point. On enclosed ultra-silent and super-silent generators like the DCA25 series, a failing gasket can allow exhaust gases to leak inside the generator canopy, which can affect engine back-pressure, accelerate component corrosion, and create serious safety risks. Replacing a worn or blown exhaust pipe gasket restores the sealed exhaust path and is a routine part of keeping a diesel generator running cleanly and safely.
