Tube Fitting

Tube Fitting Features

  • Tube fitting Sizes range from 1/16″ to ” and 2 mm to 50 mm
  • Available for diverse materials and configurations
  • Precision machine components ensure perfect deformation of the ferrules and tubing for design
  • Hardened threads with smooth surface finish avoid galling and help to extend the fitting service life
  • Female nut threads are silver-plate to reduce the friction against the body threads
  • Radius junction design for elbows provides smooth flow path
  • Every fitting is mark with size, material and heat number
  • Fittings are easy to disconnect and re-tighten
  • 1/8″ to 5/8″, 3 mm to 16 mm fittings available with EC-79 certification

FITOK ferrule is treated with high level hardening process, both the hardness and the corrosion resistance are strengthened.

ferrule work on Tube
Ferrule Treated

Process            : Low temperature carbonization for the whole ferrule Thickness of coating : 25~30μm
Hardness          : HV0.2 800~1000
Salt spray test   : 600h no rust
Magnetism       : No
Hardened threads with smooth surface finish avoid galling and help to extend the fitting service life
