Product Details
The Fuel Injector 131406440 has been improved to address the traditional nozzle burn off defect. However, this PerKin 404D-22 Injector has a precise injection angle that does not deflect, preventing fuel from washing the top of the piston on one side and avoiding localized high-temperature burning of parts. This reduces the risk of major engine failures such as cylinder pulling and piston damage at the root.

Our Advantages
We are a genuine manufacturer boasting 30 years of specialized fuel injector production experience, running our own independent factory equipped with high-temperature aging ovens and sealed cabin heat accumulation simulation testing equipment. All sealing components go through strict material screening and performance testing to cope with harsh confined engine compartment operating conditions.
This product is specially designed for enclosed high-temperature environments in the cabin. The customized high-temperature resistant sealing components maintain stable physical performance under continuous heat radiation; they will not soften, melt or develop oil leakage issues even under long-term heat exposure. The premium sealing material stands up to severe heat buildup in narrow, poorly ventilated compact spaces, eliminating hidden troubles of fuel seepage caused by aging or melting gaskets that plague ordinary injectors. Reliable sealing performance keeps fuel delivery stable at all times, avoids engine power attenuation and safety hazards brought by oil leaks, and extends the overall service cycle of the injector assembly.
We support flexible small trial orders with an MOQ of merely 4pcs to cut down your preliminary cooperation risk. You can request product samples and conduct confined high-temperature endurance tests with your professional testing instruments to verify the outstanding heat-resistant and leak-proof performance of our seals before placing large bulk restocking orders.




FAQ
1.Is it feasible to use diesel wax to freeze the fuel injector and bake it with fire?
It is strictly prohibited to use open flames for baking. High temperatures can burn the solenoid valve and deform the housing. The correct way is to replace low-grade diesel and preheat the external oil circuit.
2. Is it normal for the fuel injector return flow to increase under low temperature conditions?
As the viscosity of low-temperature diesel increases, the return oil will slightly increase. After heating up, the standard flow rate will be restored. If the return oil exceeds the standard at room temperature, it is a fault.
