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.

Push-to-Connect Tube Fittings for Air
- Temperature Range: 0° to 170° F, except polybutylene plastic fittings are 32° to 140° F
- Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
- Specifications Met: ISO 14743, except cartridges and polybutylene plastic fittings
Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.
Identification rings (sold separately) snap over the release ring so you can color-code your lines.
Clips (sold separately) align and organize your tubing and fittings.
Fittings with PTFE thread sealant offer extra protection against leaks.
Metric male threads have either a gasket or a thread sealant to protect against leaks. BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Fittings with external hex or slotted drive allow for easy adjustments in tight spaces; they are also known as banjo-style fittings.

Reels with Double Lightweight Air Hose
Hose is PVC, so it’s lighter and less cumbersome than rubber hose. It locks in place when pulled out of the reel, and retracts with a quick tug.
