Vario Couplings, PVDF
Two-part coupling made of PVDF for connecting elastic tubing (e.g. Viton®, Tygon®, silicone) to hard-walled tubing made of PTFE, glass or other plastics. Easy and ingenious functioning: the elastic tubing is pushed on a cone and fixed on the coupling by means of a connecting nut. On the other side, the hard-walled tubing is connected to a flanged PTFE tubing with miniature connectors (e.g. Cat. No. F 702), female thread UNF ¼''28 G.
- Temperature resistance: from -40°C to +170°C
- Chemical resistance: very good
- Pressure: 3 bar
- Vacuum: suitable

Miniature Luer-Lock Connectors, PTFE
Connection of componets with Luer Lock such as syringes or cannulas to a tubing system.
Temperature resistance: from -200°C to +250°C
Chemical resistance: very good
Connector made of PTFE for transition from Luer Lock connection to female thread UNF 1/4'' 28G. The inner cone of the Luer-Lock connection provides good sealing, the additional thread (either male or female) prevents accidental loosening. The tubing is connected by means of tube end fittings to a female thread UNF 1/4'' 28G.

Quick connectors, Shut-off coupling, Serie 3 K
- designed to be connected and disconnected quickly and frequently.
- The quick connectors of our Series 3K are safe because a shut-off element seals the line before the coupling is disconnected.
- To connect or disconnect the coupling, simply actuate the sliding sleeve. Reliable operation is guaranteed by our choice of material: the coupling is made of PVDF and the spring of PEEK, stainless steel or Hastelloy®.
