The Multiquip 8971713310 is a genuine OEM Gasket Injection Nozzle DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator series. This is a direct OEM replacement sourced through the Multiquip parts network, ensuring the correct material grade and sealing geometry for the 4LE2 engine's fuel injection system. If you're servicing a DCA25USI unit, using the correct nozzle gasket is critical to maintaining a leak-free, properly pressurized fuel delivery circuit. DHS Equipment stocks this part to keep your generator service on track.
Key Features
- OEM Sealing Specification — Manufactured to the exact compression and material grade required by the Isuzu 4LE2 engine's injector nozzle seat, ensuring a proper fuel-tight seal under operating pressure.
- Drop-In Installation — Matches the original injector nozzle interface on the DCA25USI, seating correctly without reworking the nozzle bore or injector hold-down hardware.
- Confirmed Fitment: DCA25USI — Specifically referenced for the DCA25USI ultra-silent diesel generator powered by the Isuzu 4LE2 engine.
- Fuel System Integrity — A correctly seated nozzle gasket maintains the injector's rated opening pressure and spray pattern, supporting efficient combustion and consistent generator output.
- Fuel Safety Compliance — An intact injection nozzle gasket prevents high-pressure fuel leakage at the injector seat, which is a critical safety and emissions concern on diesel-powered equipment.
The injection nozzle gasket forms the sealing interface between the fuel injector nozzle and the engine's cylinder head. Its job is to contain the extreme pressure generated during fuel injection and prevent combustion gases from blowing back past the nozzle seat. When this gasket is worn, damaged, or improperly torqued, the result can be fuel leakage, loss of injection pressure, incomplete combustion, and potential heat damage to the injector and surrounding head material. Replacing it with the correct OEM part — Multiquip 8971713310 — ensures the injector is properly isolated and the fuel system operates at its designed specification.
