Fuel lines are designed to contain liquid fuel or fuel vapor.
This includes all hoses or tubing for the filler neck, for connections between under floor piping,
and for connecting a carbon canister to the fuel tank
The construction of the fuel tubes material consists of the following types:
Common used material are PA11 or PA12. Suitable for fuel lines with medium permeation requirement.

A unique 3 layers wall thickness tube developed with technology from EMS Switzerland. The 3 layers consist of outer PA12 material,
barrier layer of EVOH and inner layer of PA6 material delivering exceptional toughness and corrosion resistance.
Suitable for fuel lines system with low permeation requirement and fuel with ethanol content up to 100%.

The end fitting design can be in:
a. Quick connector or spool – A. Raymond
b. metal coupling or adaptors
c. End beads (connected with short rubber hose with constant pressure clips) - for vapor lines only
Operating condition:
- Working pressure up to 20 bars
- Burst pressure up to 60 bars
- Pull off force up to 250N
- Temperature 140 degree C peak. However, special high temperature grade material is available for higher temperature requirement.
Chemtube fuel lines provide:
- Medium to low permeation rating with high performance barrier properties
- Good chemical resistance
- Excellent mechanical properties
- Long-term aging and durability
- Flexibility
- Good impact strength at low temperature
Corrugated fuel lines (Fuel filler)
Made of advanced high precision corrugation technology with choice of monolayer or multilayer constructions.
Suitable for fuel filler hose and breather hose application. Corrugated hose length and shape can be customized to suit customer requirement.
