A spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect couplings. This reduces turbulence, foaming, bubbles, and blockage. They have a shut-off valve that stops the flow when the coupling is disconnected, so air or water won’t leak from your line. Unlike couplings with a button release, these have a safety slide to reduce accidental separation from bumps or drops. They’re often used in laboratories, pharmaceutical facilities, and other sterile environments. All are FDA compliant for direct contact with food.

When you insert the plug into the socket, it’ll connect with a click. To disconnect, slide the latch on the socket and remove the plug.

Acetal plugs and sockets are stronger and harder than polypropylene plugs and sockets, making them less likely to scratch. Their slippery surface also makes them more wear resistant. They resist moisture, so they won't crack or become brittle when used in humid environments.

Polypropylene plugs and sockets are flexible yet tough, so they keep their shape and strength after repeated use. They are more water resistant than acetal plugs and sockets and can be completely submerged.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

Made of plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle. Quick to attach and detach, they’re often used in lines that are frequently disconnected. They have a compact body for easy installation in tight spaces. Use them in low-pressure applications. These couplings are open-flow style, so there is no shut-off valve to stop the flow when they’re separated.

Plugs with a locking ring are more secure than those without a locking ring. Give the ring a half turn to lock these couplings in place. You can’t remove the locking ring.

Note: For a complete coupling, order a plug and a socket.

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings. This reduces turbulence, foaming, bubbles, and blockage. They have a shut-off valve that stops the flow when the coupling is disconnected, so chemicals won’t leak from your line. Unlike couplings with a button release, these have a safety slide to reduce accidental separation from bumps or drops. They are often used in laboratories, pharmaceutical facilities, and other sterile environments.

Made of PVDF, also known as Kynar, these couplings have excellent chemical and UV resistance at ambient and elevated temperatures. They also resist abrasion, impact, flames, and corrosion. Compared to other quick-disconnect couplings for chemicals, these couplings can withstand higher temperatures—all the way up to 250° F.

When you insert the plug into the socket, it’ll connect with a click. To disconnect, slide the latch on the socket and remove the plug.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

With just a half turn or a light push, these valves connect to luer lock fittings on your line. Their universal connection size fits any luer lock plug or socket.

Polycarbonate valves are lighter in weight than metal valves, but they aren’t as durable.

Connections without a locking ring are quicker to install and remove than those with a locking ring. Also known as luer slip connections, all they need is a light push. Add a snap-on ring (sold separately) to lock your connection in place and color code your line.

Connections with a locking ring are more secure than those without a locking ring, so they’re better for high pressures. Give the ring a half turn to lock them in place. You can’t remove the locking ring.

To prevent leaks, these valves have barbed fittings that grip onto tubing to create a strong hold. They meet NSF/ANSI standards or are FDA compliant for use with food. All are full port, so they do not restrict flow.

Nylon valves meet NSF/ANSI 18 for use with manual food and beverage dispensing equipment.

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.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. They operate on electricity to automatically start and stop flow.

Valves are normally closed unless actuated. They don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
