Pressure Hoses : Edelmann power steering pressure hose covers are highly resistant to oil, heat and ozone which cause ordinary assemblies to fail prematurely. Tube construction withstands internal oil temperatures of up to 300 degrees Fahrenheit. Double piles of high-tensile strength braided fabric help Edelmann pressure hoses to withstand pulsation pressures up to 1,500 psi and bursting pressures up to 8,900 psi. Tubing is Pro-coated or terne coated and couplings and fittings are zinc-chromate plated for rust and corrosion protection.
