Heater Hose


A technically advanced range of convoluted hoses with stainless steel rings to absorb the relative movement between engine and intercooler. Specially developed convolutes minimise resistance to flexing and loads transferred to connection spigots.

The critical design benefit is determined by laboratory load movement trials. The functional integrity is approved after accelerated dynamic testing, which simulates vehicle operating conditions.

Optimum durability and flexibility over extended service periods whilst operating at extremes of temperature.

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.
