About Series 500

Compact size with a unique tamper-resistant, one-piece design characterizes our Series 500 Miniature Modular Check Valves. This series allows you to combine any two end fittings or use the same configuration on both ends. Connections include both hose barb in 1/16" or 1/8" options and male or female luer styles to meet a wide range of applications. Easily mounted in-line for liquid or air applications, our miniature check valves eliminate the leak prone adapter seen in other valves by combining the fitting and check valve in one piece. At Smart Products USA, all of our valves are customizable by plastic body material, o-ring material, and opening spring pressure to meet a specific application criteria.
