On/Off Valves with Quick-Turn Fittings
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.
Nickel-plated brass valves are more corrosion resistant and durable than polycarbonate valves, however they are heavier and more expensive.

On/Off Valves with Barbed Fittings
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.
Lever handle valves provide the best leverage, so they’re good when you want to quickly open and close valves with minimal effort.
Nickel-plated brass valves are more corrosion resistant than plain brass valves.
Valves with tapered barbs can be used with multiple tube sizes.
Valves with Buna-N rubber seals resist water and oil. Valves with fluoroelastomer seals are more resistant to chemicals and temperature fluctuations than those with Buna-N rubber seals. They’re good for systems that are flushed with hot fluids or cleaners.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Compact Threaded On/Off Valves
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.
Short-lever handles and T-handles resist accidental movement when snagged or bumped. Lever handles are easy to open and close—they give you the most leverage of any handle type.
Valves with threaded outlets can connect to pipe or hose, giving you more control over where your fluid flows than valves with a drain or spout outlet.
Valves with a drain or spout outlet direct flow to a drain or bucket with minimal splashing. Install valves with a drain outlet to the bottom of a tank. Install valves with a spout outlet to the side of a tank.
