Question by: Lance K on Aug 23, 2025, 7:01 PM

these are listed as interchangeable with Swagelok fittings -- so if I already got Swagelok ferrule sets on my tubing runs, I can just swap these in without any rework?

Answer by: Customer Support on Aug 24, 2025, 8:11 PM

Duolok fittings are manufactured and quality controlled to be fully interchangeable with the Swagelok brand, so yes, swapping them into existing installations where Swagelok ferrule sets are already in use is exactly the kind of application these are built for. Same 0.38 inch tube OD, same double ferrule design. No rework needed on the tubing side.
