Product Questions & Answers

These fittings interchangeable with Swagelok? Got a bunch of Swagelok stuff already on the line and just need to know if these'll drop right in without a headache.

Question by: Todd J on Feb 19, 2026, 7:51 PM

Compatible and interchangeable with Swagelok brand fittings, yes. SSP builds these to be gaugeable and quality controlled to the same standard, so swapping them into an existing Swagelok setup is straightforward. The double ferrule design carries over the same pull-up behavior during installation, so your crew won't be dealing with any surprises on the line.

got a 3/8 inch stainless tube line, is this union the right size for that?

Question by: Johnny M on Apr 12, 2025, 10:07 AM

For a 0.38 inch tube outside diameter, this union matches that tube OD. It is a Duolok double ferrule tube fitting meant for instrumentation and process tubing systems.
