Gasoline Hose Lines – Advanced Fuel Handling Solutions

Colmec’s Gasoline Hose Lines are designed using state-of-the-art technology to meet the rigorous performance, safety, and emission standards required in modern fuel systems. These systems can be custom configured to produce a range of hose types suited for various fuel transport applications.

Technical Features & Construction

  • Flexible Mandrel Extrusion:
    • Hoses are extruded over a flexible mandrel, allowing for:
      • Consistent internal diameter
      • Ease of removal post-curing
      • High production flexibility for varying shapes and lengths
  • Multilayer Structure:
    • Designed with multiple functional layers to balance mechanical strength, chemical resistance, and flexibility
  • Inner Barrier Layer:
    • Made of a thin fluoro-plastic substrate (e.g., ETFE or PFA)
    • Acts as a fuel-impermeable barrier
    • Reduces evaporative emissions in compliance with environmental regulations (e.g., EPA, CARB)
  • Co-Extruded Fluoro-Elastomer Layer:
    • Incorporates fluoro-elastomers (such as FKM or FVMQ) via co-extrusion
    • Enhances chemical and thermal resistance, particularly for aggressive fuel blends like E10, E85, or biodiesel
  • Textile Reinforcement:
    • Embedded braided or knitted reinforcement (e.g., polyester, aramid)
    • Provides:
      • High burst pressure resistance
      • Dimensional stability
      • Abrasion resistance
  • External Rubber Coating:
    • Durable outer layer protects the hose from:
      • Ozone
      • UV rays
      • Mechanical wear

Specifications Overview

  • Extruded on flexible mandrel for form stability and production efficiency
  • Multilayer construction ensures optimized performance in harsh environments
  • Fuel barrier: Fluoro-plastic inner layer (e.g., ETFE) minimizes permeability
  • Co-extrusion with fluoro-elastomers for added durability and sealing integrity
  • Textile reinforcement supports high-pressure operation and longevity

Key Application Areas
