Our low gas permeability LPG CNG gas hose is purpose-built for automotive LPG and CNG vehicle gas conversion systems. Engineered for safe fuel transmission inside converted vehicles, this hose delivers stable, long-term performance for autogas workshops, installers and vehicle modification projects.
Hose Internal Structure
Inner Tube: Black smooth synthetic material, resistant to LPG & CNG fuel, heat-ageing and features low gas permeability to minimize fuel leakage risk.
Reinforcement Layer: High-strength braided fiber reinforcement to maintain structural integrity under operating pressure while preserving good flexibility.
Outer Cover: Black smooth synthetic cover with excellent resistance to LPG/CNG media, heat ageing and ozone erosion caused by harsh under-hood environments.
Key Product Features
Good Aging Resistance: Maintains physical performance under long-term high-temperature working conditions.
Premium Ozone Resistance: Outer cover resists ozone cracking for extended service life.
Excellent Heating Resistance: Continuously withstand working temperature up to +125ºC, adapting to vehicle engine compartment heat.
Low Gas Permeability: Effectively reduces gas permeation loss and improves system safety.
Good Flexibility and Easy to Install: Flexible construction fits complex wiring layouts inside vehicles, convenient for field installation work.
Application Scope
This autogas hose fits a wide range of vehicle models and different autogas system configurations. It is widely applied for passenger cars, taxis, light commercial vehicles and other gasoline-to-gas converted vehicles. Strict internal quality standards are followed during production to guarantee safe usage and reliable field performance. It is an ideal spare-part choice for LPG / CNG fuel-system installation and daily maintenance work.
Frequently Asked Questions
Q1: Can this hose be used for both LPG and CNG vehicle conversion systems?
A1: Yes. This hose is specially developed for automotive LPG and CNG dual-use autogas systems, suitable for most sequential-injection and single-point gas conversion kits.
Q2: What is the maximum continuous working temperature for this auto gas hose?
A2: It can resist continuous operating temperature up to +125 ºC, suitable for normal engine-compartment thermal environment.
Q3: Does low-gas-permeability design really improve system safety?
A3: Yes. Low-permeability inner tube material reduces gas molecule penetration through hose walls, lowering potential hidden risks caused by gas permeation for enclosed vehicle cabins.
Q4: What installation tips should installers notice?
A4: Avoid sharp twisting and excessive sharp bending during installation. Keep away from direct high-heat sources as much as possible, and inspect hose surface regularly for cracks or ageing after long-term running.
