Tube Fittings

Product ID: Twin Ferrule

Through the mechanical advantage and geometry, the tube fittings can overcome the variations in materials, wall thickness and hardness to provide an excellent seal performance.  Twin ferrule design is a mechanism used to provide a bubble-tight connection and achieve sealing and gripping tubing functions.  Through the mechanical advantage and geometry, the double ferrule tube fittings can overcome the variations in materials, wall thickness and hardness to provide an excellent seal.



There are 4 main parts of the fittings, nut, body, front and back ferrules. Nut is silver-plated to increase lubrication and reduce galling.  Double ferrules are for seal and grip.  The front ferrule of the tube fittings creates a seal against the fitting body and on the tubing outside diameter. Once the nut gets tightened, the back ferrule axially advances the front ferrule and provides an effective grip.


Taking good advantage of advanced machines, we also have strict quality management system to make sure every detail goes perfectly well.  The twin ferrule tube fittings we provided are with consistent reliability.  Please feel free and contact us for further information about our product today!

  • Double ferrule design
  • Nut silvered plated
  • Size:
    1/8”O.D. ~1”O.D.
    6mmO.D. ~25mmO.D.
  • Thread: NPT, BSPT, BSPP.
Features:
  • Designed to provide a bubble-tight connection and achieve sealing and gripping tubing functions
  • Through the mechanical advantage and geometry, the tube fittings can overcome the variations in materials, wall thickness and hardness to provide an excellent seal performance
  • When the nut is tightened, the back ferrule is driven against the tapered rear of the front ferrule
  • The front ferrule is driven by force into the tapered mouth of the fitting body and creates a primary tubing seal
  • The back ferrule consistently grips the tube to hold the tubing firmly in place while the front ferrule forms a full-faced seal on the tapered surface of the body
  • In the twin ferrule design, the back and front ferrules move axially instead of a rotary motion. No Torque is transferred to the tubing during installation
  • Pressure ratings are determined by the wall thicknesses of tubings on which they are installed.  Please refer to maximum working pressure on the catalogue
