Joined Firm Rubber Tubing for Air and Water
- Flexible
- Compatible with Barbed Tube Fittings
- Firm (See table for hardness rating)
- Temperature Range: -40° to 160° F
Run multiple tubing lines together without the hassle of cable ties or tape. This tubing comes joined for a clean, organized look. It's flexible enough to easily bend around objects without kinking. No matter how you twist, bend, or stretch this tubing, it returns to its original shape. Made of ether-based polyurethane, it has excellent resistance to tearing and abrasion and stays strong and durable, even in humid environments.
Single color tubing can't be separated. Multicolor tubing can be peeled apart for applications that require fewer tubes.
Clear tubing allows you to monitor flow through the line. Opaque tubing does not let you see inside the line.

Multiline Quick-Disconnect Tube Couplings for Air
Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once. They keep tubes organized and optimize space in tight spots. Often used in robotics, these couplings are ideal for complex pneumatic systems.
Through-wall couplings allow you to connect and disconnect air lines on a panel or machine. This is useful when you are going to transport and reconnect your equipment on site.
Barbed-connect fittings are for soft tubing.
For a complete coupling, order a plug and a socket with the same coupling size.

- Maximum Pressure: 100 psi @ 72° F
- Temperature Range: -40° to 180° F
- Tubing: Use with soft or firm (Durometer 45A-90A) polyurethane rubber or PVDF plastic
Connect the coupling with a push and disconnect by pressing the latch. Made of plastic, these couplings are lighter in weight than brass couplings.
If you want the coupling to rotate freely after it’s installed to avoid kinks in your tube, choose one with a swivel.
