Import Fuel Injection Hose — Buy in Bulk from Supplier in China

The Fuel Injection Hose supplied by Conflex Oil Hose Co., Ltd. is constructed with a fluoroelastomer rubber tube, a thermoplastic barrier, an adhesion layer, textile spiral reinforcement, and a CSM outer cover. It is designed for both pressure-side applications up to 225 psi and return-side applications up to 50 psi, with low permeation properties to reduce hydrocarbon emissions. The product is used in diesel and gasoline systems, including those running on biodiesel blends up to E85.

The inner tube is made of fluoroelastomer, which resists degradation from gasoline, diesel, methanol, and ethanol blends. The thermoplastic barrier layer significantly reduces fuel permeation compared to conventional rubber hoses, meeting environmental standards for vapor emissions. The textile reinforcement is not suitable for high-pressure use, limiting its application to return lines only. The CSM cover provides resistance to ozone, abrasion, heat, and weathering, extending service life in under-hood environments.

This hose is commonly sourced by manufacturers of light trucks, passenger vehicles, and small diesel engines for OEM and aftermarket replacement. Buyers typically require it in coil or reel form, packed in boxes. No minimum order quantity is specified. Lead time, packaging dimensions, and certification status for SAE J30R7 or ISO 14334 are not provided and must be confirmed directly with the supplier.
