Heater Hose


Heater hoses are used to transport coolant within diesel engines when the situation requires lower pressures and longer lengths than standard applications. Available in Single braided or Knit polyester reinforcement with heavy wall configurations for high pressure applications.

Continuous progress resulting in improved methods of manufacture and materials.

Innovative product development ensures that your products are available in advance of all new emission regulations.

Silicone Coolant Applications

Silicone out performs conventional hose materials in terms of optimum reliability and long life on engine, radiator, heater and other coolant handling applications.

In house accelerated ageing and dynamic testing of finished hoses replicate long term application which means you can fit it and forget it. 

Mandrel wrapped format to conform to the requeremnts of SAE J20 R1 (standard wall) class ‘A’. Alternatively in single ply construction, manufactured by continuous methods, to conform to the requirements of SAE J20 R3 and R$ class ‘A’.

Materials are chosen by technical engineers based on the application requirements and specifications.
