【Product Basic Overview】

The THV fuel filler hose is a core special pipeline accessory for the fuel tank filling link of the fuel system. Made of advanced multi-layer composite co-extrusion vulcanization process with fluororesin and special rubber, it solves common pain points of ordinary fuel hoses such as excessive fuel penetration and volatilization, potential safety hazards of static electricity accumulation, easy cracking and aging from outdoor ozone and sun exposure, embrittlement and softening in high and low temperature environments, and swelling and leakage from long-term fuel transportation. Developed and produced in strict accordance with GM6289M technical specifications, it has excellent fuel barrier and penetration resistance, fully complying with Euro IV motor vehicle environmental protection emission regulations, effectively reducing fuel volatilization loss and air pollution. The multi-layer composite structure is tightly bonded without delamination, bulging or cracking. The flexible hose adapts to complex vehicle cabin wiring, withstands vehicle driving vibration, temperature alternation, outdoor wind and sun and other complex working conditions. Stable fuel filling and conveying without oil leakage, static electricity or aging for a long time, it is an optimal environmentally friendly and safe special pipeline for fuel filling systems of passenger cars, engineering vehicles and special machinery.

【Product Structure & Core Material Description】

1. Inner NBR Oil-Resistant Rubber Layer: Made of high-quality nitrile rubber with excellent basic fuel resistance, corrosion resistance to gasoline, ethanol gasoline and other media, no swelling, oil leakage or deformation. The smooth inner wall ensures smooth oil transmission and reduces fuel flow resistance. 2. THV Fluororesin Barrier Layer: Core functional fluororesin composite material with ultra-low fuel penetration, strongly blocking fuel volatilization and leakage, meeting Euro IV emission environmental protection standards, reducing fuel loss and air pollution fundamentally, with penetration resistance far exceeding ordinary single-layer rubber hoses. 3. AR Intermediate Adhesive Reinforcement Layer: Special adhesive base material, strengthening the bonding strength of multi-layer structures, improving the tensile and flex resistance of the hose, no delamination or degumming for long-term use, and stabilizing the overall structural stability. 4. Outer CSM Weather-Resistant Protective Layer: Chlorosulfonated polyethylene weather-resistant rubber material, ozone resistant, UV resistant and weather aging resistant, adapting to long-term outdoor sun and rain exposure and temperature changes, no cracking, pulverization or hardening for long-term use, fully protecting the internal composite structure.
