Polytetrafluoroethylene (PFA) valves, connectors: chemical tolerance, can withstand chemical solvents. Can be used as a variety of chromatographs, chemical equipment and other pipeline connection control. Divided into the same diameter reducing.

Features:

1. Appearance translucent jade.

2. High and low temperature resistance: can be used temperature -200℃ ~ +250℃.

3. Corrosion resistance: strong acid, strong alkali, aqua regia and various organic solvents, and no dissolution, adsorption and precipitation phenomenon.

4. Anti-pollution: low blank value of metal elements.

5. Insulation: not affected by the environment and frequency, small dielectric loss, high breakdown voltage.

6. Atmospheric aging resistance, radiation resistance and low permeability.

7. Self-lubricity: small friction coefficient of plastic.
