Features and Advantages
Superior Flexibility - Highly engineered polyester material exhibits improved flexibility versus traditional nylon tubing. Excellent Resistance - Excellent resistance to abrasion, gasoline, diesel fuel, road salt and deicing compounds. Industry Leading Impact Strength and Vibration Cracking Resistance - Engineered formulation retains its flexibility and resists impact cracking in both high heat and sub-zero cold weather conditions; providing longer service life than traditional nylon tubing. Exceeds Industry Performance Standards - Far surpasses traditional nylon tubing for heat aging and heated oil aging, while retaining its superior performance and flexibility over lower temperatures than traditional nylon tubing. Easy Installation - Greater flexibility allows for easier installation reducing time, effort and installer fatigue. Weather Resistant - Heat and light stabilized for superior UV resistance and long service life. Resists the cracking that can result from damaging UV light.
CompliancesMeets and exceeds DOT FMVSS 106 Meets and exceeds performance requirements of SAE J844
