Butyl EPDM Aramid Reinforced Low Permeation Hose for EVAP & Automotive Emission Systems
Technical Structure
- Inner Layer: Butyl Rubber (Low Permeation Barrier)
- Reinforcement: Aramid Fiber Braiding
- Middle Layer: EPDM Rubber
- Outer Layer: EPDM Rubber (Weather Resistant)
- EVAP carbon canister connections
- Fuel vapor transfer lines
- Vacuum control hoses
- Emission control systems
- Low-pressure gas transfer systems
Modern emission systems require hoses that not only resist pressure, but also prevent molecular-level fuel vapor leakage.
Traditional rubber hoses (EPDM or NBR) may not provide sufficient barrier performance over long service life. This butyl-based composite structure is engineered to minimize permeation while maintaining mechanical strength and flexibility.
