Question by: Sheila R on Mar 28, 2026, 8:56 AM

these ferrule sets, are they gonna work as a drop-in swap if I already got Swagelok fittings installed on my tubing runs?

Swapping these in for Swagelok hardware is exactly the kind of situation these are built for. SSP Duolok fittings are manufactured and quality controlled to be fully interchangeable with Swagelok brand tube fittings, so you won't need to re-engineer anything. The 0.50 inch tube OD sizing stays consistent, and the double ferrule design will seat the same way you're used to.
