HPLC PEEK Large Head Finger Tight Fittings are precision fluid handling components designed for High-Performance Liquid Chromatography (HPLC) and UHPLC systems requiring secure, leak-free connections and convenient tool-free installation. Manufactured from high-performance Polyether Ether Ketone (PEEK), these fittings provide exceptional chemical resistance, high purity, and long-term reliability in demanding analytical environments.
Designed with a 10-32 UNF thread for use with 1/16" OD tubing, these fittings feature an enlarged head profile that improves grip and allows easy hand tightening, simplifying installation and routine maintenance. The PEEK construction eliminates the risk of corrosion and metal ion contamination while maintaining compatibility with a wide range of solvents commonly used in chromatography.
PEEK large head finger tight fittings are widely used in chromatography systems, laboratory instrumentation, sample preparation equipment, and precision fluid handling assemblies where reliable sealing, ease of use, and contamination-free performance are critical.
Available for chromatography, laboratory, and precision fluid handling systems.
