Copper Capillary Tubing

 

Copper Capillary Tubing used for restrictor applications use as per ASTM B360 “Standard Specification for Hard-Drawn Copper Capillary Tube for Restrictor Applications” for quality and production requirements.

When further fabrication requires other tempers, tubing can be made to your specifications. Hand Coil, Spooled Coils (Bulk), Random Bunch Coils Straight Lengths (Boxed)

The Standard: Tubing is placed into “Random Bunch” coils with a range of 5 to 20Kgs. per coil.

Option: Spooled Coil where random length of tube is wound onto cardboard reels with a range of 100Feet Length per coil.

Option

  • Random lengths of straighten tube are produced.
  • Exact lengths of straighten tube are produced.
  • Fabrication such as Copper Bulb attachment or Forming into Coiled Assembly can be quoted.

 

Standard sizes available for Restrictor Applications are provided in the table below and also listed within ASTM B360-95.
