Chemical transfer hose
Multi-layer chemical hose resistant to acids, alkalis, and solvents. Available with PTFE liner for aggressive chemical transfer applications.
Best for: chemical processing plants, tanker loading, industrial fluid transfer
Chemical transfer hose EPDM/PTFE
Our chemical transfer hoses are engineered to handle the most aggressive industrial fluids safely and reliably. Multi-layer construction combines a chemical-resistant tube with reinforcing ply for burst strength and an abrasion-resistant cover.
For standard chemical applications, EPDM tube offers excellent resistance to dilute acids, alkalis, and polar solvents. For aggressive chemicals including strong acids, chlorinated solvents, and oxidizing agents, our PTFE-lined hoses provide near-zero permeation and maximum safety.
Challenges solved by correct chemical hose selection
Chemical permeation through hose wall
Standard rubber hoses allow chemical vapors to permeate through the tube wall over time, creating safety hazards, strong odors, and environmental compliance issues. Our PTFE-lined hoses provide a near-impermeable barrier that eliminates permeation even against aggressive solvents and chlorinated compounds.
Hose swelling from chemical attack
Incompatible tube materials absorb chemicals and swell, reducing bore diameter, delaminating reinforcement layers, and eventually causing burst failures. We match the tube compound precisely to your chemical composition and concentration — EPDM for moderate duty, PTFE for aggressive chemical attack.
Coupling corrosion from chemical drip
Chemical residue that drips or pools at hose connection points corrodes metal couplings over time, creating leak paths that worsen with each use cycle. Our chemical hose can be fitted with PVDF, polypropylene, or 316 stainless steel couplings that resist chemical attack, and the hose cover is designed to shed drips rather than pool them.
Case study: Agrochemical blending facility, Vietnam
How PTFE-lined transfer hoses eliminated solvent permeation and passed environmental audit.
Situation: An agrochemical blending plant in Binh Duong was using standard EPDM rubber hoses for solvent-based pesticide concentrates. Operators reported strong chemical odors, hose swelling within weeks, and monthly replacements that disrupted batch production.
Solution: Replaced all solvent transfer hoses with PTFE-lined chemical hose with stainless steel braid reinforcement and EPDM cover. Installed full-vacuum rated assemblies for tanker unloading operations.
Outcome: Chemical odor eliminated in the blending area. Hose replacement interval extended from 1 month to over 14 months. Environmental audit passed with zero non-conformances. Operator safety concerns fully resolved.

Chemical transfer hose FAQ
Chemical compatibility depends on the tube material, concentration, temperature, and exposure duration. Our EPDM tube resists dilute acids, alkalis, and ketones. PTFE (Teflon) liners offer near-universal chemical resistance including strong acids, solvents, and oxidizing agents. We maintain a chemical resistance chart covering thousands of industrial fluids — contact our team with your specific chemical and operating temperature for a verified recommendation.
PTFE (polytetrafluoroethylene) liners provide near-zero permeation against aggressive chemicals, preventing hazardous vapors from escaping through the hose wall. PTFE is chemically inert, non-stick, and handles temperatures from -20°C to 120°C. It resists virtually all industrial chemicals including strong acids, bases, solvents, and oxidizing agents. The trade-off is lower flexibility compared to rubber hoses and higher cost.
Temperature ratings depend on tube material. Standard EPDM chemical hoses are rated from -20°C to 100°C. PTFE-lined hoses extend the range to -20°C to 120°C. For elevated temperatures above 120°C, special silicone or PTFE constructions are available. Note that chemical aggressiveness increases with temperature — a fluid that is compatible at 20°C may attack the tube at 80°C. Always verify compatibility at your operating temperature.
