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.

Plastic Quick-Turn Tube Couplings with Shut-Off for Air and Water

- Temperature Range: -50° to 150° F
- Tubing: Use with firm or soft (Durometer 35A-85A) PVC plastic or silicone rubber, except fittings with pipe end
A built-in shut-off valve stops the flow when the coupling is separated, so air or water won’t leak from your line. Also known as luer lock couplings, these consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body, so they’re easy to fit in tight spaces. Couplings have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size. They are nylon, which is lightweight with good impact and abrasion resistance.
Note: For a complete coupling, order a plug and a socket.
