S4R PFA Equal Tube Union Tees are designed to connect three equal-size fluoropolymer tubes in laboratory, chemical and fluid-handling systems. Their PFA construction provides broad chemical resistance while the compact three-way configuration enables convenient fluid branching in analytical equipment, electrochemical systems and laboratory fluid-transfer assemblies. Selected metric and fractional tube sizes are available for common laboratory installations.
