About Us
20 Years of Excellence in Fuel Injection
Injector Factory is the online store of Wuhan Ranyingyi Trading Co., Ltd. — a factory-direct manufacturer of diesel fuel injection systems. Our factory is located in Zhoukou, Henan, China. For 20 years, we have engineered and produced common-rail injectors, nozzles, control valves and high-pressure pumps covering the world’s major systems — Bosch, Denso, Delphi and CAT — for automotive, marine, agricultural and industrial applications.
What sets us apart:
- VIN/OEM fitment verification — Send us your VIN or OEM number and our technicians verify exact compatibility before you order. No guessing, no wrong parts.
- Factory bench-testing — Every injector is tested for spray pattern, leakage and response before shipment.
- Full-range catalog — From passenger-car common-rail to heavy-duty truck and marine injectors, plus nozzles, valves and repair kits.
- Global B2B & retail supply — Stocked inventory for fast processing, worldwide shipping, and dedicated after-sales technical support.
Our promise: 6-month warranty on core injectors, 3 months on wear parts — covering manufacturing defects, no hassle.
