Our unique 316L VIM / VAR stainless steel body offers minimum dead space for maximum flow. Diaphragm valves are ideally suited for use in a wide variety of industrial applications including ultrahigh purity processes in semiconductor, biotech, and pharmaceutical manufacturing. Outstanding design and engineering of Hy-Lok valves make them the ideal products for reliable and safe operation.

Two ferrule tube fittings are designed and manufactured to meet the rigorous specifications required of industrial applications. Hy-Lok tube fittings are commonly used throughout the oil and gas, pulp & paper, petrochemical/chemical processing, research laboratories, aerospace and defense, chemical processing, power generation, cryogenic and semiconductor, shipbuilding and heavy industrial industries. Available in numerous configurations and sizes, our tube fittings are made up of four parts consisting of a body, front ferrule, back ferrule, and nut. Outstanding leak-tight connections are consistent as the two-ferrule design compensates for any tolerances in tube outer diameter, wall, thickness, and material hardness.
