They handle extra pressure without requiring any extra tools or extra effort

When you need a robust fitting that can handle up to 20 000 psig with an easy installation, Swagelok medium pressure fittings are a great solution. Download the Medium- and High- Pressure Fittings Catalogue to find out more.


Earlier this year we wrote about Swagelok's IPT fittings for high-pressure applications. But maybe you are looking or something that takes less time to install and can be verified for proper installation. For pressures that don't go beyond 20,000 psig (1378 bar), consider Swagelok's line of medium-pressure fittings.

With our medium-pressure fittings, you don't need any special tools or special skills. You don't have to cut threads or cone the ends of the tubing, as you would for the high-pressure fittings.

The simple two-piece design of Swagelok's medium-pressure tube fittings and adapters consists of a female fitting body and preassembled cartridge containing the male nut and color-coded front and back ferrules on a disposable plastic arbor. The preassembled cartridge ensures that installers will have the correct ferrule orientation, plus visual confirmation when the ferrule is present and properly installed in the female body.

The components are released only after the nut is threaded finger-tight on the fitting body.

Key differences

While Swagelok's medium-pressure fittings don't require special tools or skills, their installation differs from standard Swagelok fittings in a few key areas. 

First, it takes only one full turn to pull up the fitting, not the turn-and-a-quarter of our standard fitting. Second, proper tightening can be measured by torque as well as with our gap-measuring gauge. Third, Swagelok's medium-pressure fittings are designed to industry standards rather than using a proprietary design. That means this is one of the very few components in the Swagelok catalog that can be mixed into your fluid system without having to upgrade all the fittings at once.

In our medium-pressure line we have straight fittings, 90-degree elbows, tees and union crosses, plus caps and plugs.

The strain-hardened stainless steel bodies offer lightweight space-saving designs. You'll also get Swagelok's patented low-temperature case hardening processing of the ferrules and nut.

Your fluid system needs to run on the right pressure for the job, and you need the right fittings for the pressure. Edmonton Valve & Fitting can make sure you get the right match. Call us at 780-437-0640 or contact us through our website.

Looking for your own copy of the new and revised Swagelok Tube Fitter's Manual, look no further! If you are in our sales and service area, request a copy of the new print edition here. PDF work better for you? Request the online PDF version.


Since its debut in 1963, the Swagelok Tube Fitter's Manual has been the industry standard. It's the result of extensive field research and laboratory studies conducted by Swagelok's research and development engineers, plus feedback we've received over the years from our customers. The original author, Joe Callahan Jr., went on to become the president of Swagelok.

As technology has progressed, Swagelok updated the manual in the '70s, '80s and '90s. Now a new 6th edition is being made available, both in a softcover version and as a free Internet download.

The latest edition now includes information on metallurgy, innovations in product design, advanced manufacturing processes, and selecting tube fittings for severe service requirements.

More than fittings

The Swagelok Tube Fitter’s Manual is intended to help you avoid many of the problems encountered on tubing installation projects. The manual provides a quick reference to technically accurate design and installation information.

While the manual is primarily about Swagelok tube fittings, it also covers important aspects of tubing, valves, troubleshooting and pressure ratings. To take just one example, a tube fitting can do its job properly only if the tubing material is softer than the fitting material. So you wouldn't want to put stainless steel tubing in a brass fitting. Tubing wall thickness, proper handling, and proper layout are all covered in the manual as well.

There's also an entire chapter on the hidden cost of leakage.

The new edition maintains the manual’s respected, iconic status as “the Tube Fitter’s Bible” while positioning it as the premier multimedia reference source on tube fittings for Swagelok customers in the 21st century. To expand on the wealth of information in the manual, we added a QR code that links to important supplemental information, such as catalogues, publications, or videos.

Revised and updated

Swagelok Company has updated and revised the content five times in the past 51 years, and now the entire new 321-page edition is available both as a free softcover version or in a downloadable PDF format. The 10 chapters (and three appendices) cover the Swagelok tube fitting itself, plus tubing specification and ordering, tubing and tube fitting handling and installation, severe service, troubleshooting, special purpose fittings, testing and evaluation of tube fitting performance, pipe threads, pressure ratings, the hidden costs of leakage, valves, and more. 

As Callahan wrote in the original preface, "The well-known Swagelok two-ferrule fitting is the best tube fitting we know how to manufacture; however, proper installation and use of high quality tubing will go far to ensure leak-free connections."

No trouble

Any complex system will have its share of challenges. The manual has a whole chapter on troubleshooting to keep frustrations to a minimum.

If the tube will not go into the fitting, for instance, there could be any of a half-dozen causes from burrs on the end to simply using the wrong size tubing. If the system leaks, there is a good chance the fitting was not installed properly. The manual explains what to look for when the leak happens after initial installation, after reassembly following maintenance, and under high temperatures.

If you'd like to get this classic, all you have to do is to ask for it. You will get a better understanding of how Swagelok tube fittings work, and how to get the best performance out of them.
