Compression fittings are easy to attach and disassemble, making them convenient for home plumbing and DIY projects. These fittings require tight clamping to keep the tubing from rotating within the fitting, which could loosen the nut and cause a leak.

Compression fittings include an outer nut that presses an inner sleeve, or ferrule, onto the end of a pipe or tube. The inner sleeve compresses on the tube and keeps the tube locked into the fitting. Once the sleeve is compressed it cannot be removed; the nut may be reused if it has not lost its form.
Brass compression fittings connect pipes and tubing through two or more ports. Brass creates a durable, corrosion-resistant fitting. These fittings have a cylindrical body with rings on the front and back and nuts on each end. A brass ring slides onto the pipe before connecting the fitting to tighten the seal and prevent leaking without soldering or extra tools. Brass fittings are easy to install, but they should not be used underground. Brass tube fittings are used in applications for plumbing systems, hospitals, laboratories, construction, vehicles, aeronautics, and many others.
