Double Bite Ferrule Fittings

Double bite ferrule fittings

Double bite ferrule fittings are a type of mechanical connection used in tubing systems, commonly found in industries such as hydraulics, pneumatics, and instrumentation. These fittings are known for providing a secure and leak-proof connection between tubes or pipes.

Here's a detailed overview of their characteristics, applications, and advantages


Double bite ferrule fittings
Double Ferrule System:
  • Comprises two ferrules (a front ferrule and a back ferrule) that grip the tube.
  • The front ferrule forms a seal between the fitting body and the tube.
  • The back ferrule provides a grip on the tube, ensuring that the connection remains tight.
  • Materials:

  • Typically made from stainless steel, brass, or other corrosion-resistant materials
  • Suitable for high-pressure and high-temperature applications.
  • Design:

  • The fittings are designed to be easy to install and require no special tools for assembly.
  • They are reusable, which means the fittings can be disassembled and reassembled without losing their sealing integrity.
  • Applications

    Hydraulic Systems:
  • Used in high-pressure hydraulic systems to ensure leak-proof connections.
  • Pneumatic Systems:
  • Provide reliable connections in systems that use compressed air or other gases..
  • Instrumentation:
  • Ideal for connecting instrumentation tubing where precise measurements and reliable performance are critical.
  • Process Control Systems:
  • Employed in chemical processing, oil and gas, and other industries that require robust and durable fittings..
  • Advantages

    Leak-Proof Seal:
  • The double ferrule design ensures a tight and reliable seal, minimizing the risk of leaks.
  • High Pressure and Temperature Resistance:
  • Suitable for demanding applications where high pressures and temperatures are common.
  • Ease of Installation:
  • Can be easily assembled and disassembled without the need for special tools.
  • The fittings can be reused, which can be cost-effective in the long run..
  • Versatility:
  • Available in various sizes and materials, making them suitable for a wide range of applications.
  • Vibration Resistance:
  • The design provides excellent resistance to vibration, which is crucial in dynamic systems.
  • Installation Steps

    Cut the Tube:
  • Ensure the tube is cut squarely and is free of burrs.
  • Insert the Tube:
  • Insert the tube into the fitting until it bottoms out.
  • Tighten the Nut:
  • Tighten the nut by hand, then use a wrench to tighten it further according to the manufacturer's specifications.
  • Inspect the Connection:
  • Verify that the connection is secure and leak-free.
  • Double bite ferrule fittings are a reliable and versatile choice for many applications requiring durable and leak-proof connections. Their ease of installation and reusability make them a popular option in various industries..
