Vacuum Hose
Brake booster is an enhanced master cylinder setup used to reduce the amount of pedal pressure needed for braking. It employs a booster set up to act with the master cylinder to give higher hydraulic pressure to the brakes and/or lower force applied on the brake pedal. The brake booster usually uses vacuum from the engine intake to boost the force applied by the pedal on to the master cylinder. The main function of Vacuum Hose Assy. is to provide passage for vacuum pressure transmitting from the engine to the master cylinder.
Chemtube’s vacuum hose is made of high performance Nylon PA6, PA11 or PA12 materials. The hose consists of single layer nylon hose, thermoformed to design intend shape with check valve at one end and a fitting at the other end. The hose diameter, shape and end connection can
be customized to meet customer’s requirement.
Operating Condition
- Maximum pressure up to 10 bars
- Pull off force up to 1KN
- Temperature 140 degree C peak. However, special high temperature grade material is available for higher temperature requirement
Chemtube’s Nylon Vacuum Hose Delivers
- Light in weight
- Excellent mechanical properties
- Long-term aging and durability
- Easy to form to shape without heavy duty machine
- Flexibility

Fuel Tube Assemblies
A fuel line is a hose used to bring fuel from one point in a vehicle to another or from fuel storage tank to engine inlet. 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 fuel tube is made of high performance nylon material with end quick connectors fitted at both ends. The construction of the fuel tubes material consists of the following types:
Monolayer Fuel Lines
Single layer wall nylon tube with good chemical and mechanical properties. Common used materials are PA11 or PA12. Suitable for fuel lines with medium permeation requirement.
We also produce fuel lines with different raw material grades which are requested by our customers. *
Multilayer Fuel Lines
A unique 2 or 3 layers wall thickness tube developed with European technology delivering exceptional toughness and corrosion resistance. Suitable for fuel lines system with low permeation requirements and fuel with ethanol.

Clutch Tubes
Clutch system is used in vehicles with manual transmission. Clutch acts as a coupling device to separate the engine and transmission during gear changing or stagnant condition. The clutch tube carries hydraulic oil and provides the link between clutch master cylinder and engine transmission.
Chemtube’s single layer clutch tube is made of high durability Nylon PA12 material, thermoformed to intended design shape with overmoulded connector with O-ring at both ends. The hose diameter, thickness, shape and end connection can be customized to suit customer’s requirement.
The end fitting design can be in:
a. Overmoulded end connector with o-ring
b. Metal adaptor (optional)
Operating Condition
- Maximum pressure up to 65 bars
- Pull off force up to 1KN
- Temperature 140 degree C peak.
