How do I use Swagelok?
Step 1 fully insert the tube into the fitting. And against the shoulder rotate the nut to make sure it is finger tight. Step 2 mark the nut at the six o’clock position.
Can you over tighten Swagelok fittings?
If a fitting is over-tightened, it reduces the number of times a fitting can be reassembled. Using proper techniques, you’ll be able to disassemble and reassemble Swagelok tube fittings many times.
How tight do you tighten Swagelok fittings?
Position. Third while holding the fitting body steady with a vise or backup wrench tighten the nut one and one-quarter turns until the mark reaches the nine o’clock.
How are Swagelok fittings measured?
To determine whether your threads are straight or tapered, use a caliper to measure the male or female thread’s crest-to-crest diameter on the first, fourth, and last full threads. If the diameter increases on a male end or decreases on a female end, the thread is tapered.
Do Swagelok fittings need Teflon tape?
No Teflon tape or sealant is utilized on these threads. There may be, however, certain applications where the installer may wish to utilize a compatible lubricant to reduce galling of these threads.
Can you reuse Swagelok fittings?
If you have made changes in the system design, by moving a fitting to a new location or changing the tubing, you can’t re-use the nuts and ferrules, but you can still re-use the fitting bodies.
How do I stop my compression fitting from leaking?

How do you read an fitting?
The numbers used for sizing refer to the outside diameters of the tubing in 1/16” increments. So, for example, a -2 fitting is equivalent to 2/16 of an inch or 1/8”. That means, a -3 fitting equals 3/16”, a -4 equals 4/16” (i.e. 1/4”) and so on.
When should you not use Teflon tape?
An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free connection.
Can too much Teflon tape cause leaks?
This is a critical factor if you’re planning to use Teflon tape for a DIY project, since Teflon tape can actually cause leaks if misused. For example, if you’re working on PVC, copper or PEX pipes, these use alternate bonding methods and Teflon tape isn’t necessary.
Can Swagelok ferrules be reused?
If you have made changes in the system design, by moving a fitting to a new location or changing the tubing, you can’t re-use the nuts and ferrules, but you can still re-use the fitting bodies. Even on a simple connector, you are saving a big percentage of the cost of using all-new parts.
What does Swagelok VCR stand for?
vacuum coupling radiation
VCR means vacuum coupling radiation, providing leak-tight service from vacuum to positive pressure. The VCO line uses an O-ring to form a seal.
What is the most common cause of leaking compression fittings?
If the nut is overtightened the ferrule will deform improperly causing the joint to fail. Indeed, overtightening is the most common cause of leaks in compression fittings.
Should I use Teflon tape on compression fittings?
“Should I use PTFE thread sealing tape or pipe joint compound on my compression threads?” A. No, you definitely should not. PTFE tape and pipe joint compound (also known as “pipe dope”) should only be used on “IPS” (“iron pipe size”) threads, which are normal pipe threads.
How do I know what size an fitting I have?
You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).
Why are AN fittings red and blue?
Traditionally, AN Fittings are produced in a red/blue color combination, which served as a nod to the origin in army and navy applications for many years.
How many times do you wrap threads with Teflon tape?
Step 4: How many times the thread seal tape will go around the pipe depends on the thickness of the tape, but for the standard variety, about five or six wraps should be enough for the job.
Do you wrap Teflon tape clockwise or counterclockwise?
clockwise
How to apply teflon tape on threads – is there a correct way? Yes. You must apply thread tape by turning it clockwise around the thread. When the fitting is connected, the fitting is installed the same clockwise direction, sealing the fitting & not pealing back.
How many times do I wrap Teflon tape?
Where should you not use Teflon tape?
How do Swagelok ferrules work?
The use of plastic ferrules allows for a “non-permeant” seal which means the ferrule sets can be easily removed and reused on new tubing. In contrast, once metal ferrules are swaged in place they cannot be removed or reused. The position of the ferrule sets must be correct for the Swagelok™ fitting to work properly.
Are Parker and Swagelok fittings interchangeable?
Is Parker CPI™ Really Interchangeable? Yes. All threads, the seal seat angles and position, tube insertion depth, hex sizes and width, etc., are the same as Swagelok®. The fitting is totally the same as Swagelok® in all functional dimensions of the body and nut.
What are VCR fittings used for?
Swagelok VCR metal gasket fittings are the preferred fittings in the semiconductor industry for high-purity gas delivery systems. They are used when the demand for fast, easy and reliable maintenance is needed on components in a welded system. When a failure occurs in a welded system repairs can be costly.
How tight should you tighten a compression fitting?
Hold the compression fitting body tightly with a pair of grips and tighten the nut with a spanner. Its often said in the trade to not over tighten a compression fitting, leaving you more thread in the case of a leak and not distorting the olive or fitting. Generally a nut will need one whole turn after hand tightening.
What does 4AN mean?
