VHP PK LiteTouch® Fittings

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.
