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.

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. These valves open to allow flow in one direction and close when flow stops or reverses. The clear body allows you to visually inspect flow and debris accumulation.
