International. Parker Hannifin recently launched a new series of silicone hoses for thermal management applications. The 6722 X-Treme series of extruded silicone hoses complies with the SAE J20 R3 class A standard and can be installed not only as a thermal management solution, but also in trucks, buses, engines or other applications where there is a requirement for a highly efficient heating/cooling circuit.
Thermal management relates to the various heat transfer processes (conduction, convection, condensation and radiation) used to increase, maintain or decrease the temperature of a system or component.
Parker's low-permeability silicone hose is suitable for a wide range of coolants and can withstand ozone and UV onslaught more efficiently than other materials. The 6722 series is not only resistant to oxidation and chemicals, but also stable at extreme operating temperatures ranging from -54°C to +177°C, as in an engine compartment.
Parker's 6722 X-Treme series doesn't lose its flexibility and elasticity over time. This reduces the risk of cracking, hardening or decomposition, and increases the possibility of installations in narrow and restricted spaces, and where there are obstructions. In addition, the new hose offers good vibration and sound dampening performance. All of these benefits help extend service life and reduce maintenance costs, downtime, warranty and logistics, while preserving circuit and equipment performance.
Parker silicone hoses provide the necessary features for the increasing number of industrial applications where the thermal management capacity of other rubber hose solutions is not adequate.
