Knowledge of Compression Fittings and Usage in Chemyx Pumps

What is a compression fitting?
A compression fitting compresses a component of the fitting into another component, usually some type of tubing, to create a watertight seal between two different lines. The compression fitting can handle high pressure and give you a reliable, tight seal. A compression fitting is comprised of a sleeve, a nut, and the fitting body itself. The sleeve acts as the seal when the nut compresses it into the fitting body.

How do you install and remove a compression fitting?

Compression fittings are simple to install but require a wrench in most cases. They consist of three components: the sleeve, nut, and fitting body. All components work together to create a watertight seal. To create this seal, you must:
1. Slide the nut onto your tubing.
2. Slide the sleeve up to the nut on its threaded side.
3. Put the tubing into the connector on the fitting body, and pull the nut, and then the sleeve, down so that the threads on the nut meet the threads on the fitting body.
4. At that point, you will screw the nut onto the fitting body.
5. Use your wrench to tighten the connection.
To remove the fitting, simply do the same thing in reverse. When you pull the sleeve out of the fitting body, the sleeve will stick to the tubing. If you’re just putting the sleeve right back into the fitting body, or you’re connecting the same tubing to a new angle-stop configuration, you can simply reuse the sleeve. If you are not reconnecting the tubing to another form of a compression fitting, you will have to cut the sleeve off to remove it from your tubing.

Where are compression fittings used in Chemyx products?

Compression fittings are used in a variety sizes of stainless-steel syringes of Chemyx The stainless steel syringes are most used at Fusion 6000 High pressure syringe pump. They might be used at other models of syringe pumps like Fusion 4000 and Fusion 200 if the pressure of the applications are not high.

What are compression fittings made from?

Compression fittings are made from a variety of materials. The compression fittings Chemyx provide are made by stainless steel. Depending on the material or your fitting, the amount of pressure or temperature that the fitting can withstand will vary.
How much pressure can a compression fitting withstand?
The amount of pressure a compression fitting can withstand is simple to understand. Usually, a stainless steel will withstand more pressure than a plastic fitting, and so forth. Typically, you can find a fitting’s pressure rating online.

What do you do if your compression fitting is leaking?

If a compression fitting is leaking, you should determine where the leak is coming from. Usually, if you have a sound connection, you’ve put the fitting together properly, and you’ve wrenched down to where it’s good and tight, the fitting is not likely to leak. Unless a piece of tubing is moved and puts some strain or torque on the fitting itself, the seal should be tight and complete.
If leaking happens, you would need to take the fitting apart and reassemble it once you’ve inspected it for any malfunction. Hopefully, after reassembling, your leak will stop. If not, you may have to replace the fitting, or a piece of it, and the tubing that was connected to it.
