Product Pressure Ratings
Maximum Operating Pressures
Carbon Steel Fittings and Adapters
Recommended maximum working pressures are based on limited laboratory test data and intended only as approximate guidelines, based on a 4:1 safety factor relative to the connection minimum burst pressure. Testing was conducted at SAE recommended assembly torque in hardened test blocks. The maximum pressure for any adapter or tube fitting must be lower of the chosen mating end types. Pressure ratings must be adjusted for any change in adapter material.
All pressure ratings are shown in pounds per square inch (psi).
