Install these valves in tight spots, such as where pipelines are crowded together. They’re less than half as long as standard threaded valves and one-third shorter in height. Use with water, oil, air, and inert gas.

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.

Also known as luer-lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line. Use these valves with water and oil.

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.
