Pressure Ratings

IMPORTANT SAFETY - READ FIRST
Listed maximum working pressures are based on laboratory test data and intended only as guidelines.  The test data is based on a 4:1 safety factor relative to the connection's minimum burst pressure. Testing is conducted at SAE recommended assembly torque.  

The maximum pressure for any adapter or fitting must be lower than the chosen mating end types. Pressure ratings must be adjusted for any change in the adapter material.
