Attach a gauge to the side port on these valves to monitor pressure, temperature, and other measurements in your line. Use with water and air.

These valves have barbs that grip onto tubing, providing a secure hold. Because they’re made of metal, they are more durable than plastic valves and withstand higher temperatures.

Monitor and maintain flow quality from a single valve. Thanks to their solder-connect union fitting, these valves are especially useful in lines that require frequent maintenance and cleaning.

For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems.

Also known as stop cocks, install these valves on your tank for easy draining of air or fluid.
