In high-performance liquid chromatography (HPLC) systems, ensuring reliable tubing connections is crucial for maintaining consistent flow paths and obtaining accurate analysis results. Our HPLC PEEK unions and reducing adapters are specifically designed to connect different tubing sizes, such as 1/16″ and 1/8″. Made from high-quality PEEK material, these connectors offer exceptional chemical resistance, durability, and compatibility with a wide range of HPLC fluidic systems.
Our selection includes 1/16″ straight PEEK unions, 1/8″ straight connectors, and 1/16″ to 1/8″ reducing adapters, providing versatile solutions for laboratory instrument connections and customized fluid handling configurations. The precision-machined design ensures secure fittings and reduces dead volume, making them ideal for analytical chromatography applications where the reliability and performance of connections are paramount.
