HINO J08C Engine Injector Nozzle Rubber Sleeve S2374-51020 | Diesel Fuel Injector Seal

Product Details

Product Overview

This high-quality HINO J08C Nozzle Rubber Sleeve (Part Number: S2374-51020) is a critical component for maintaining optimal fuel injection pressure in HINO diesel engines. Designed as a direct replacement for the OEM fuel injector seal, this rubber sleeve prevents fuel leakage and contamination between the injector nozzle and the cylinder head. We supply this part globally to markets including North America, Europe, Southeast Asia, the Middle East, and Africa, ensuring fast and reliable shipping for B2B clients in the heavy-duty truck, bus, and construction machinery sectors.

Key Features & Benefits

• Precision Fitment: Manufactured to exact OEM specifications (S2374-51020) for a perfect seal on HINO J08C injectors.
• High Durability: Constructed from high-grade nitrile rubber (NBR) that resists diesel fuel degradation, high temperatures, and pressure cycling.
• Leak Prevention: Effectively prevents external fuel leaks and internal compression gas blow-by, protecting the engine oil from dilution.
• Cost-Effective: A direct alternative to expensive dealer parts without compromising on quality or service life.
• Easy Installation: Simple to replace during routine injector maintenance, reducing downtime for fleet vehicles.

FAQ

Q1: Is this the same as the copper washer for the injector?
No. This is the rubber sleeve (also called an O-ring or seal) that fits around the injector nozzle body. It seals the upper part of the injector bore. The copper washer is a separate component that seals the combustion chamber at the tip. You may need both for a complete injector service.

Q2: How do I know if my HINO J08C needs this sleeve replaced?
Common signs include fuel odor around the engine, visible fuel wetness on the cylinder head near the injector, or a rough idle caused by air entering the fuel system. If you are replacing injectors, it is highly recommended to replace these sleeves as a preventative measure, as they harden over time with heat.

Q3: Can this sleeve be reused after injector removal?
No. Rubber sleeves are a single-use crush seal. Once the injector is removed, the sleeve will be deformed and will likely leak if reused. Always install a new S2374-51020 sleeve when reinstalling injectors to ensure a proper seal and prevent future engine issues.
