- Durable in use.

5) Application:
Stainless capillary tubing is widely used in many industrial applications, such as:
- Precision instruments and appartus
- Liquid and gas lines
- Electronic&electric applications
- Automatic apparatus

Precision Stainless Steel Pipe for us means stainless capillary tubes. It is steel pipe of small internal diameter; used in refrigeration as a control for the flow of liquid refrigerant or as an expansion device between the condenser and evaporator; or used to transmit pressure from the sensitive bulb of a temperature control to the operating element.
