Injector

Common rail, mechanical and unit injectors plus nozzles, seal kits and copper washers for Cummins, CAT, Isuzu and Yanmar diesel engines.

Injectors are matched to the OE number and engine code, because the same body is built in several flow ratings. Send the OE number with the engine code and we confirm the correct injector before packing.

Why Choose Our Injectors

Fuel system components selected for performance and durability.

  • Precision Fit

    Machined to OEM references for reliable installation and long service life.

  • Material Integrity

    Casting and forging quality controlled for heavy-duty thermal and load conditions.

  • Model Coverage

    Wide coverage across mainstream diesel platforms for fleets and rebuild shops.

  • Pack & Ship Ready

    Anti-rust protection and export crates designed for ocean freight.

Applications

Truck fuel injectors for haulage fleets, excavator injectors for construction machinery, generator injectors for standby power and marine injectors for workboats. The diesel engine injector is matched to the engine code and the OE number, because the same body is built in several flow ratings. Heavy-duty injectors for continuous duty are quoted against the rating you run.

Types we quote

The catalogue covers common rail injector, mechanical injector, electronic injector and unit injector designs, each supplied as a complete injector assembly. Where only the nozzle is worn, an injector nozzle assembly or just the injector nozzle tip can be quoted on its own.

Installation parts

Injectors are usually ordered with the injector seal kit, the injector o-ring, the injector copper washer, the injector spring and, where the body is reused, the injector holder. Telling us which of these you already have keeps the order to what you actually need.

Condition

New, remanufactured, rebuilt, used, original and aftermarket injectors are quoted separately, with the condition stated on the quotation. A remanufactured common rail injector and a replacement fuel injector assembly are the two most common orders.

Questions buyers ask

Should I replace the injector or just the nozzle?

If the body and solenoid are sound, a nozzle assembly is enough. If the injector is leaking internally or the correction values are out of range, fit a complete assembly.

Do you supply seals and washers with the injector?

Yes. Seal kits, o-rings and copper washers are quoted with every injector.

Can you match a diesel fuel injector to an excavator?

Yes. Send the OE number, the engine code and the machine model, and we confirm the injector for excavator use before shipping.
