VHP high-performance fittings

Product / Chromatography

The IDEX VHP (Very High Pressure) series is designed for the extreme pressures of HPLC and UHPLC systems, connecting 1/16" tubing OD to 10-32 coned ports. Some are made of stainless steel, some of a proprietary PEEK blend (PK) and some of a combination. The PK polymer has minimal cold flow compared with pure PEEK and withstands high pressures and temperatures up to 200 °C; as it may be conductive, caution is needed in high-voltage applications.
