Stainless Steel Luer Lock Tube Couplings for Air and Water
Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings. Luer lock connections are universal, so you can connect any plug and socket to each other, regardless of the pipe or tube size. You can also connect them to syringes and needles. These couplings have a compact body, so they’ll fit in tight spaces. All are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated.
303 stainless steel couplings have very good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
Note: For a complete coupling, order a plug and a socket.
Brass Quick-Disconnect Tube Couplings for Air
- Temperature Range: 0° to 180° F
- Tubing: Use with hard polyethylene plastic or polypropylene plastic
An all-brass body gives these quick-disconnect couplings better durability than plastic quick-disconnect couplings. They’re nickel plated for very good corrosion resistance. Couplings consist of a plug and a socket that join with a latch, so you can easily connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch and remove the plug.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so air won’t leak from your line.
Compression plugs and sockets have a sleeve (ferrule) that compresses the tubing and forms a seal when you tighten the nut.
Through-wall sockets are also known as bulkhead sockets and panel mount sockets; they mount through your wall or panel to create an inlet or outlet.
