Idex – VHP Fittings – VHP PK Fittings

Our UHPLC fittings are manufactured from a proprietary PEEK blend (PK) which allow them to be used at higher temperatures (up to 200 °C) and higher pressures. The VHP PK One-Piece fittings are available for 10-32 coned, 6-32 coned, or M4 coned ports, and Two-Piece fittings are available to connect either 1/16 inches or 1/32 inches outer diameter tubing into 10-32 coned ports in multiple styles. VHP MicroFerrules are made from a proprietary high performance PEEK polymer blend, a material which is unique in its ability to enable the use of capillary tubing in UHPLC environments. The new high pressure MicroFerrules are available for use with 1/32 inches or 360 μm outer diameter tubing, and they are incorporated into several of our VHP products for capillary tubing.

Our Very High Pressure (VHP) LiteTouch Fitting is manufactured from a proprietary PEEK blend (PK) which allows it to be used at significantly higher temperatures (up to 200°C). This material’s characteristics allow the ferrule to operate at much higher pressures than conventional PEEK. Our LiteTouch design is ideally suited for tubing assemblies for coned ports. The mechanical design of the ferrule effectively prevents tubes from twisting.
