Features
- Multi-functionality
A multifunctional hose designed to efficiently transport not only liquid fuel but also evaporative gases from the fuel tank.
- Excellent Durability
The outer cover is made of rubber with superior ozone and weather resistance (e.g., CSM), effectively preventing aging caused by exposure to ozone and UV rays in external environments.
- Enhanced Low Fuel Permeation
To comply with North American environmental regulations (such as LEV III, PZEV), a THV resin (Tetrafluoroethylene, Hexafluoropropylene, and Vinylidene Fluoride polymer) barrier is applied. This minimizes fuel evaporation and ensures stable long-term performance.
- Versatile Material Composition
Utilizing a range of special rubber materials—including FKM (Fluoroelastomer), ECO (Epichlorohydrin), NBR (Nitrile), CSM (Chlorosulphonated Polyethylene), and THV—ensures superior chemical resistance and outstanding durability against fuels and oils.
PyungHwa Advantages
- Designed for exposure to external elements, the outer cover features rubber with superior ozone and weather resistance to enhance durability.
- To comply with tightened North American environmental regulations regarding evaporative emissions, our THV hoses utilize a resin known for its excellent low fuel permeation and adhesion, ensuring stable performance.
