Product Questions & Answers

these swap right in for Swagelok fittings, yeah? got a 1/4 inch tube line I need to plug off and don't want to have to source a whole different brand

Question by: Phil M on Nov 8, 2025, 6:17 AM

Correct on both counts. Duolok fittings are manufactured to be fully interchangeable with Swagelok brand tube fittings, so swapping one in for the other on a 1/4 inch tube line is a straightforward substitution. No adapter or modification needed.

these Duolok fittings are designed to work just fine with copper tubing.
