Ultra-High Performance Fingertight Fittings

Upchurch Scientific®'s line of Ultra-High Performance fittings are manufactured from a proprietary PEEK blend that allows them to be used at higher temperatures (up to 200ºC) and higher pressures (up to 23000 psi / 1585 bar in some cases) than more traditional fittings. These Ultra-High Performance Fittings are available in the popular one-piece 10-32 fingertight style, as well as two-piece 10-32 and 1/4-28 styles and are designed for use with 1/16" and 1/32" OD tubing. Our new Ultra-High Performance fittings are well suited for high temperature applications in which biocompatibility is important and metal fittings are undesirable, such as protein analysis and ion chromatography.
