The most demanding HPLC applications require fittings that will meet higher pressure requirements than standard chromatography fittings can accommodate. This patented line of VHP fittings are perfect for use in high-performance analytical systems. The VHP reusable fittings can be up to ten repeat assembly cycles without impacting pressure-holding ability when proper torque tightening specifications are followed. Increased component life can be achieved with a polymer front ferrule, which will not damage the tubing or receiving port.
