Pipe Ferrule


A pipe ferrule is a type of pipe fitting made of various materials used especially for joining or binding one part to another (as pipe sections). A pipe ferrule consists of a circular clamp which is used to hold together and attach fibers, wires or posts. It is a type of a ring or cap attached to an object to protect against damage, splitting or wear. A pipe ferrule is also known as a circular fitting device that is used to hold the pipes together.

Pipe ferrules are available in various sizes. Pipe ferrules of larger sizes are designed in such a way that they have special hardening processes which can offer better leak resistance and tube holding at higher pressures.

Materials used:
Various materials are used to make pipe ferrules like as follows:
  • Copper
  • Aluminum alloy
  • Cast steel
  • Stainless steel
  • Plastic
  • Ceramic
  • Glass
Two parts of pipe ferrule:
  • Nut
  • Body

Buying Tips

Things to look for:
  • Nominal pressure
  • Nominal diameter
  • Applicable medium: oil, water, gas, and other corrosive, non-corrosive medium
  • Corrosion resistance
  • Applicable temperature
  • Material
  • Concerted pipes diameter
  • End thread
  • Reasonable structure
  • Tight tolerance
  • Reliable sealing function
  • Long service life etc.
Types of pipe ferrule:
Single Ferrule

Single ferrule:

In the single ferrule, the nose of the ferrule is used to perform two functions—one to bite into the tube to hold it and two to provide a sealing element for the coupling body.


Double Ferrule

Twin/Double ferrule:

The twin/double ferrule uses grip by the back ferrule and seal by the front ferrule.

Industrial applications:
A pipe ferrule is used in various industries such as:
    Pipe Ferrule
  • Hardware
  • Electrical & electronics
  • Fiber optics
  • Lawn and garden instruments
  • Automotive
  • Compressed-gas
  • Fire suppression
  • Welding
  • Furniture
  • Beverage

Benefits of Pipe Ferrule:
Some important benefits of pipe ferrule are as follows:
  • Pipe ferrules are used widely in compression fittings for attaching piping.
  • They are used with the connector to connect the fiber cable either to another cable or to a transmitter or receiver.
  • Pipe ferrules keep the fibers accurately aligned within the connector.
  • Pipe ferrule is used to align and protect the stripped end of a fiber.
