Stainless Steel Duolok Tube Fitting, 0.63 Inch Tube OD To 1/2-14 Male NPT, Straight

Description & Features

Engineered from 316 stainless steel Duolok fittings ensure a dependable leak-proof connection for instrumentation and process tubing systems. The innovative double ferrule design adapts to varying tubing materials hardness and wall thickness providing reliable leak-tight connections across diverse applications.

These fittings manufactured and quality controlled to be gaugeable offer sufficient pull-up during initial installation. The interchangeability feature ensures compatibility with Swagelok brand tube fittings facilitating versatile usage.

Typically Duolok fittings match the maximum allowable working pressures of the recommended stainless steel tubing. Note that specially designed bored-through AN O-Ring Seal and SAE integral end fittings may exhibit lower pressure ratings.

Constructed to function in a wide range of temperatures these fittings maintain performance even in extreme conditions though elevated temperatures may reduce the maximum working pressure capability. Certified material test reports (CMTRs) are available ensuring traceability and compliance with ASTM standards.

these fittings interchangeable with Swagelok? got some existing lines already using that brand and wanna make sure i don't have to swap everything out

Answer by: Customer Support on Dec 28, 2025, 6:51 AM

Duolok fittings are manufactured and quality controlled to be fully interchangeable with Swagelok brand tube fittings, so mixing them in an existing system is not a problem. The double ferrule design follows the same pull-up and gageability standards, which means you can swap in this fitting without reworking the surrounding connections.

got a 5/8 tube line, is this the right straight fitting to go over to 1/2-14 male npt?

Answer by: Customer Support on Apr 2, 2025, 8:23 AM

The tube side is 0.63 inch tube OD and the thread side is 1/2-14 male NPT, in a straight body. It is a Duolok double ferrule tube fitting, so it is meant to make a leak-tight connection on the tubing when it is pulled up correctly.

Question by: Janet E on Dec 5, 2025, 6:18 PM

What kind of temperatures can this fitting handle without any issues?

Answer by: Customer Support on Dec 7, 2025, 10:11 AM

These Duolok tube fittings are able to function reliably across a wide range of operating temperatures. Keep in mind that elevated temperatures may reduce the maximum working pressure capability of the tubing system.
