About On/Off Valves

Drainage Valves

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

Compact Threaded On/Off Valves

Install these low-profile valves in tight spots. Use with water, oil, air, and inert gas.

On/Off Valves with Barbed Fittings

Metal provides more durability than plastic. These valves have barbed fittings that grip onto tubing for a secure hold. Use them with water and air.

Solenoid On/Off Valves with Exhaust Port

Designed for controlling single-acting, spring-return air cylinders, these valves have a third threaded port to exhaust media.

Compact Solenoid On/Off Valves
with Push-to-Connect Fittings

Insert tubing into the fittings on these valves—no heat, solder, or flux required.

Self-Draining Breather Vents

Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain.
