PEEK Unions and Connectors

A reliable fluid path depends on every connection. PEEK unions and connectors join tubing, link components and help route liquid through HPLC and laboratory systems. They offer a polymer option where the properties of PEEK are useful at the connection point.

Straight unions bring two tubing sections together. Other connector designs can adapt between connection types or divide a flow path. In chromatography, the internal space within a connection matters: selecting a suitable low-volume design can help limit unwanted mixing outside the column.

Match the connector to your setup

Check the tubing outer diameter, port thread and port shape before ordering. Compare the connector’s bore and pressure rating with your system, and confirm that its materials suit the fluids in use. Correctly matched tubing and fittings are essential to forming a sound connection.
