Parker Hannifin, the global leader in motion and control technologies, has introduced a new silicone hose series for use in thermal management applications. The 6722 X-Treme series of extruded silicone hoses meets the SAE J20 R3 Class A specification and can be installed not only as thermal management solutions, but also on truck, bus, engine, or other applications where there is a requirement for a high efficiency cooling / heating circuit.
Thermal management relates to the different processes of heat transfer - conduction, convection, condensation and radiation - utilised to increase, maintain or decrease the temperature of a system or component.
Parker’s low permeation silicone hose is suitable for use with a wide range of coolant fluids and can withstand ozone and UV attack more efficaciously than alternative materials. The 6722 series is not only chemical and oxidation resistant, but also stable at extreme operating temperatures ranging from –54°C to +177°C such as in engine compartments.
Parker’s 6722 X-Treme series maintains its flexibility and elasticity over time. This reduces the risk of cracking, hardening, or dry rotting and increases the possibility of successful installations in narrow, restricted spaces and around obstructions. Additionally, the new hose offers good sound and vibration dampening performance. All of these benefits contribute to an extended service life reducing costs of maintenance, downtime, warranty and logistics, whilst maintaining the performance of circuits and equipment.
Parker’s silicone hoses provide the necessary characteristics for the growing number of industrial applications where the temperature handling capabilities of other rubber hose solutions are not adequate.
