What is a Swagelok compression fitting?
Compression fittings that feature a two-ferrule design can improve grip strength and seal performance. Here, a gas seal is created between the front ferrule and the outside diameter of the tubing, as well as between the seal surface of the body.
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.
Can you reuse Swagelok ferrule?

What happens when you over tighten a compression fitting?
The tubing will bulge and stick inside of the fitting if the ferrules are overly secure. If you can’t disassemble the valve or fitting, it’s a good indicator that the connection is much too tight. The only thing to do in this instance is to remove and replace the fitting in question.
What happens if you over tighten a compression fitting?
Improper Tube Fitting Connection If the valve has been over-tightened, this connection will be warped. This could lead to a whole host of problems. For example, depending on just how deformed the connection has become, it could lead to fluids being blocked, leaving them to clog up the tubes.
What type of fitting is Swagelok?
compression-grip tube fittings
When properly installed, Swagelok’s two-ferrule, compression-grip tube fittings produce a repeatable, leak-tight seal, even after being reassembled multiple times.
What pressure are Swagelok fittings rated for?
Up to what pressure can I pressurize a 10×1 mm stainless steel tubing in conjunction with the Swagelok compression fitting? Answer: The recommended working pressure for a seamless drawn stainless steel tube with a 10 mm outer tube diameter and 1 mm wall thickness is 240 bar (-28 to +37°C).
What is the most common cause of leaking compression fittings?
It is critical to avoid over-tightening the nut or else the integrity of the compression fitting will be compromised by the excessive force. 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.
What is a cap on A Swagelok?
A cap is a complete Swagelok tube fitting assembly that is used to cap a piece of tubing. It includes a nut, a front ferrule, a back ferrule, and a fitting body that is blank. The blank body allows you to pressure test your assembly before installing it into your system.
What is a a plug used for in Swagelok?
