Compression fittings are one of the most common and versatile methods of joining small-diameter metal or hard plastic tubing
Particularly useful due to their extreme temperature and pressure capabilities, and their compatibility with aggressive fluids.
Compression fittings are used in various industries, such as petrochemicals, laboratories, aerospace, shipbuilding, heavy industries etc. and they are used to make leak-free pipe connections relatively easily and quickly. Swagelok and Parker are the two leading manufacturers in the compression fittings market.
Compression fittings vary in design from manufacturer to manufacturer, but all consist of the same three basic elements: a compression nut or screw, one or more compression rings (ferrules) and a compression fitting housing. here
