Instrument/Compression Fittings

Compression fittings are used in a variety of industries for a multitude of applications. Compression fittings are most commonly used in applications where copper or brass tubing is inserted into the fitting. The ferrule then compresses the tubing, creating a watertight seal. Compression fittings can be found in everything from plumbing and refrigeration to automotive and aerospace applications. Our team is proud to offer a wide variety of standard and custom compression fittings, ensuring that you'll find the perfect solution for your needs. At Centro, we carry a complete selection of both instrument and compression fittings, available to purchase online. Please browse our website to learn more about our products and services.
