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.
Polycarbonate valves are lightweight and more economical than nickel-plated brass valves, but they are not as durable. These valves have a T-handle that resists accidental movement when snagged or bumped.
Nickel-plated brass valves are more corrosion resistant and durable than polycarbonate valves, however they are heavier and more expensive.
