  2. Identification ring 
  3. Inspection check ring 
  4. Front ferrule
  5. Back ferrule 
  6. Nut

What are Double Ferrule Fittings?

Double Compression Fittings are used in various industry to quickly and efficiently create leak-free tubing/instrumentation connections. Double ferrule fittings are made for the same purpose, but with different components. It features Nut, two ferrules, and a tube fitting body. 

These double ferrule fittings fittings are available in both metric and fractional tube sizes. Wrapping the union nut around the tube will stain the ferrule and create a strong seal. Double ferrule compression fittings provide a leak-free connection to all tolerances in the tube outer wall, thickness, diameter, and material hardness.

About Double Ferrule Fittings

Double ferrule compression fittings are the most common equipment fittings. They are regularly used in process measurement and control systems in the aerospace, defense, chemical processing plants, medical devices, oil and gas industries. The compression fitting consists of three components: nut, body, and ferrule (single or double). This design creates a sequential grip on the tube. Instrumentation tube fittings are U.N.E.F. or (United National Extra Fine) threads, the size of which is determined by the outer diameter of the tube used. 

The ferrule becomes a coin and is compressed into the tube, providing a firm grip on the surface of the tube. The male side of the Double Ferrule Instrument Fitting has a hole that matches the outer diameter-OD of the tube. In addition, an inner cone is used. The seal is between the front ferrule and the cone. Hold the tube in place by tightening the nut and letting the front and rear ferrules swage into the tube to secure it firmly. This allows flared-free tubes to be used with these connectors.
