Parker’s New Silicone Hoses

By Mike Brezonick08 November 2019

Parker Hannifin has introduced a new silicone hose series for use in thermal management applications. The 6722 X-Treme series of extruded silicone hoses are designed to meet the SAE J20 R3 Class A specification and can be installed on truck, bus, engine or other applications where there is a requirement for a high efficiency cooling/heating circuit.

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 -65º to 350º F (–54°C to +177°C) such as in engine compartments.

Parker’s 6722 X-Treme series is also engineered to maintain 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, the company said. Additionally, the new hose offers good sound and vibration dampening performance, which contributes to extended service life and lower maintenance costs.
