Question by: Harvey F on Jul 26, 2025, 2:51 PM
These Duolok fittings interchangeable with Swagelok? Got a bunch of Swagelok stuff already on the line and just want to make sure I ain't gotta rework everything.
Answer by: Customer Support on Jul 28, 2025, 8:08 AM
full interchangeability with Swagelok is built into the Duolok design. SSP manufactures these to match Swagelok dimensions and tolerances, so swapping one in where a Swagelok fitting currently sits is a straightforward drop-in. No reworking the line needed.
Question by: Rusty R on Nov 17, 2025, 9:05 AM
What kind of temperature range can this elbow handle?
Answer by: Customer Support on Nov 19, 2025, 6:39 AM
Duolok tube fittings like this one are generally reliable across a wide range of temperatures. Keep in mind that higher temperatures will reduce the maximum working pressure the tubing system can handle, so it's best to check with a specialist if you're pushing the limits.
Question by: Shane B on May 22, 2025, 7:58 PM
got a 3/4 inch stainless tube run and need to turn it 90 into 3/4-14 NPT. is this the right elbow for that?
Answer by: Customer Support on May 24, 2025, 7:53 PM
For a 3/4 inch tube outside diameter to a 3/4-14 male NPT connection with a 90 degree turn, that matches what this Duolok elbow is built for.
