PEEK Four Way Union/Cross fittings are engineered to create multiple fluid pathways within chromatography and analytical systems, allowing the distribution, combination, or redirection of flow through four interconnected ports. Manufactured from advanced Polyether Ether Ketone (PEEK), these components offer outstanding resistance to aggressive solvents, excellent mechanical stability, and contamination-free performance for high-purity applications.
Designed for use with 1/16" OD tubing, four-way union/cross fittings enable the splitting, combining, or redirection of fluid streams through four interconnected flow paths. Their low dead volume design helps minimize sample loss and peak dispersion, preserving chromatographic performance and analytical accuracy. The nonmetallic PEEK construction eliminates the risk of corrosion and metal ion contamination, making these fittings ideal for sensitive analytical and biocompatible applications.
PEEK four way unions are widely used in chromatography systems, laboratory instrumentation, flow distribution networks, and precision fluid handling assemblies where chemical compatibility, sample integrity, and reliable performance are critical.
Available for chromatography, laboratory, and precision fluid handling systems.
