Mackay’s expertise in the design and engineering of automotive hoses spans over 80 years, providing them for the very first motor cars including all Australian car manufacturers. Mackay is a 100% Australian owned company. At the Mackay hose plant based in Melbourne, the company utilities leading edge rubber technology and compounds, supported by in-house processes from rubber mixing to final product. This ensures hoses are made to the strict specifications required for the advanced motor vehicles of the 21st century.
In vehicles of today, a hose has to be designed to withstand the stresses of modern, more compact but powerful engines that run hotter and at a higher pressure. Other factors include smaller engine compartments with poor heat dissipation, aggressive coolant additives, andstray (electrochemical) current that may be conducting through the cooling system. Mackay’s research and development chemists have developed new rubber formulations and manufacturing processes that ensure Mackay hoses meet the greater wear and heat demands created by modern engines. Rubber compounds used in automotive hoses today are predominantly synthetic rubber formulations. Synthetic rubber offers excellent resistance to high temperatures, chemical attack (oils, fuels etc.), ozone, abrasion and vibration.
