Ferrules provide a reliable, leak-proof connection in instrumentation and process tubing systems. These tube fittings consist of four precision-machined components: body, front ferrules, back ferrules, and nut. Ferrules make up for the variation in the tubing material, hardness and thickness of the tube wall in order to provide leak-proof connections in a large number of applications and also reduce the number of potential leak paths in the connection, boosting safety, reliability and integrity and also simplifying assembly and maintenance.

Ferrules can generally handle pressures up to 15,000 PSI / 1,034bar. They eliminate the time-consuming 'coning and threading' that usually needs to be performed when applying traditional high-pressure fittings, allowing fittings to be installed in seconds by simply tightening a nut.

Back and front ferrules are designed to provide leak resistant, secure and tight connections for operations requiring high pressures. These fittings provide a tight pressure seal and have a long thread area for improved resistance to pressure and load on ferrules. Long support area of back ferrules improves resistance to vibration and line loads.
