The cutting ring fitting consists of the body, the cutting ring and the nut. On assembly, the two cutting edges of the cutting ring carves into the outer surface of the tube hence ensuring the necessary holding power and sealing for high operating pressures.http://www.parker.com/literature/Tube%20Fittings%20Division/EO%20and%20EO-2%20Metric%20Bite%20Type%20Fittings.pdf Parker Hannafin Catalog The tubes have usually metric dimensions.
The cutting ring fitting was invented by Ermeto in Germany in the early 1930s. Later Parker Hannifin acquired Ermeto and introduced the fittings to the US. Today they are standardized in ISO 8434.
