HPLC PEEK Bulkhead Unions are precision fluid handling components designed to create secure tubing connections through panels, enclosures, and instrument walls in High-Performance Liquid Chromatography (HPLC) and UHPLC systems. Manufactured from high-quality Polyether Ether Ketone (PEEK), these unions provide exceptional chemical resistance, high purity, and long-term reliability in demanding analytical environments.
Designed for use with 1/8" OD tubing, bulkhead unions enable fluid pathways to pass cleanly through bulkheads while maintaining leak-free connections and system integrity. The nonmetallic PEEK construction offers outstanding compatibility with aggressive solvents while eliminating the risk of corrosion and metal ion contamination, making these fittings ideal for sensitive analytical and biocompatible applications.
PEEK bulkhead unions are widely used in chromatography systems, laboratory instrumentation, fluid transfer assemblies, and analytical equipment where secure panel-mounted connections, chemical compatibility, and contamination-free performance are essential.
