Learn the basics of connections and fittings with our Fittings 101 Video Series--A practical guide to connections and fittings in your laboratory.
Nuts
The first of the two major components in a fitting system is called a nut. The nut is responsible for providing the driving force that causes the ferrule to seal. Ultimately, the choice of which nut and which ferrule to use in your system will be
dependent upon a number of parameters.
Ferrules
The ferrule compresses against the tubing to hold it in place. Ferrules aren’t nearly as complicated as their nut counterparts, but they do have some distinguishing features to help you determine which ones to use.
How Fittings Work
Fittings have 2 primary functions- leak prevention and external compression. To understand how fittings work, it’s important to know what fittings have to do.
Torque Limiting Technology
Fittings require a certain amount of torque to seal to tubing properly. The amount of torque applied will determine how well the fitting preforms. Too little torque, and the fitting will not seal, while too much torque can stress and damage the fitting, both resulting in leaks.
