These fittings get widely used to connect metal or hard-plastic tubes in industries like gas refineries, air conditioning, and plumbing systems. Compression fittings can withstand high temperatures and pressure and also tolerate strong chemicals. They comprise three components – a nut, compression rings or ferrules, and the main body.

The most convenient aspect of compression pipe fittings is that they don’t need specific installation equipment and are relatively affordable. They are also suitable for thin-walled tubing to accelerate the flow and bending.

Standard connections include a 90 degree compression fitting or an elbow joint, a T-shaped fitting, and regular coupling.
