Fuel injection hosefeatures ultra-low permeation and high working pressure. It is not
only used in fuel injection systems, but also universally used in
all fuel systems, such as power steering systems.
For different purposes, fuel injection hoses are separated into two
types – fuel injection return hose and fuel injection pressure
hose. The former is especially used on the non-pressure side (up to
50 psi), while the latter is usually found in the pressure side up
to 225 psi. Both hoses are friendly to environment for their super
low permeation and apparently save fuel in contrast to conventional
rubber hoses. They are extensively used in cars, light trucks and
other small engines.
Super low permeation
Working temperature: -40°F to 257°F (-40° C to 125°C)
Length: 25’, 50’ or 250’
Fuel injection hose consists of five plies (from inner to outer):
tube, barrier, adhesion layer reinforcement and cover.
Fluoroelastomer rubber tube is famous for its ultra-low permeation
and chemically inertness. It is quite compatible with gasoline
(leaded and unleaded), diesel, biodiesel up to E85, methanol,
ethanol and other fuel blends.
Thermoplastic barrier layer is designed for reducing fuels
permeation. It is an effective to prevent emitting hydro-carbon
vapors into the environment.
Adhesion layer is designed as the second defence when the tube
fails. It bounds together with the thermoplastic barrier,
reinforcement and cover.
Reinforcement is made of textile spiral layers. It is not suitable
for pressure side for its maximum working pressure is 50 psi.
CSM cover has excellent performances in resisting ozone
deterioration, abrasion, heat, oils, acids and weather.
