Bellows connectors for standard ground joints

PTFE, with ground joints on cone and socket.
 
Excellent chemical resistance
Gas, liquid and vacuum-tight
Temperature resistant from −200 to +280 °C
 
For use as a flexible or elastic connector to prevent pressure and stresses, and to dampen vibrations in standard ground joints. Sturdy construction with sealing rings, which prevent the ground joint from seizing and give a very good seal. No grease required, so joint grease residue cannot contaminate the analysis. Can be bent to an angle of 120°.
