Just What ARE Fittings?
Just What ARE Fittings? That’s one of the most popular questions never asked! In fact, it’s not usually until your system breaks down that you even realize all the places where fittings are used! So...just what are fittings anyway? According to the dictionary, a fitting is…
. ..a small part used to join, adjust, or adapt other parts, as in a system of pipes.
In other words, anywhere you need to attach, adapt, or adjust piping — or tubing, in this case — there’s typically a fitting involved! In fact, all kinds of fittings are used in a standard laboratory system: flanged and flangeless; metallic and non-metallic; high-pressure and low-pressure; flat-bottomed and coned; internal and external; wrenchtightened and finger-tightened.

As Paul Upchurch stated in his book entitled HPLC Fittings:
...every chromatographer knows, in order to use any HPLC system, you spend a lot of time working with fittings. You must become knowledgeable with the plumbing of an HPLC system in order to do any practical HPLC work. Because fittings impact almost everything you do with your equipment, one of the best investments you can make with your time is to better understand fittings and how to use them properly.
