Pressure Ratings for Steel Fittings
Maximum Operating Pressure (psi)
The information below is based on limited laboratory test data and is intended only as an approximate guide. The figures shown are maximum operating pressures in psi, 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 pressure rating must be adjusted for any change in adapter material. The maximum pressure for the adapter or tube fitting must be lower of the chosen mating end types.
