Thermo-Plastic HP series hoses are recommended for demanding applications. Along with their distinctive green color, the HP series hoses boast a 10,000 psi (700 bar) working, 40,000 psi (2750 bar) minimum burst, (4:1 safety factor) and a tough polyurethane outer cover that resists abrasion and wear. Well suited for continuous duty, the reinforced polyester and carbon steel wire design contributes to low volume expansion, minimized fatigue and enhanced system efficiencies.
