Specifications of High Pressure Oxygen Servicing Hoses

Hoses for high-pressure oxygen service -- such as those used for diving -- must be designed to meet two critical requirements. First, they must be able to withstand the kinds of pressures typically encountered in high-pressure service. Second, they must be able to resist the build-up of static electricity, which oxygen can create at high pressures, because a spark can easily cause a lethal explosion.

  1. Pressure Capacity

    • Standard working pressure for a high-pressure oxygen hose is 5000 PSI. Burst pressure for these hoses should meet or exceed 20,000 PSI.

    Materials

    • The interior lining of pressurized oxygen hoses should be made of low-friction materials such as high-strength thermoplastic or teflon-coated braided steel, because of the need to reduce static discharge in the hoses.

    Fittings

    • Fittings on high-pressure service hoses should be fabricated of stainless steel because of the reactivity of compressed oxygen.

    Working Temperature

    • Working temperature range for high-pressure oxygen service hoses should be from -40 degrees F to 212 degrees F.
