Gyrolok tube fittings are designed to be interchangeable. We guarantee the functional Interchangeability of HOKE Gyrolok® fittings with similar fittings of certain other manufacturers, including Swagelok®, Parker A-LOK®, and Parker CPI™.

You can interchange fittings either by using a complete HOKE Gyrolok® nut and ferrule system with a fitting body from certain other manufacturers, or vice versa. HOKE guarantees such interchanged fittings for a safe, secure, leak-tight seal, provided there is no deficiency in parts not supplied by HOKE. The properly interchanged product is covered by our standard warranty. For more information, ask your HOKE distributor.
