The large knob makes these drainage valves easy to grip.

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.

Often installed on petroleum loading arms to test fuel quality without interrupting flow, these valves are fire-tested to meet American Petroleum Institute (API) 607, Edition 5, for securely isolating fluid and preventing the spread of fire.

For lightweight and corrosion-resistant alternative to metal, these valves are plastic. Attach garden hose to the valve outlet. Use with water. These valves gradually open and close to adjust and regulate flow.
