2.4mm Air Hose | McMaster-Carr

Polyurethane rubber tubing can handle higher pressures than PVC plastic tubing and can also be used in vacuum applications. It is ether based, so it performs better in humid environments than ester-based polyurethane.

Opaque tubing doesn’t allow you to see what’s flowing through the line. Clear tubing allows you to easily monitor flow.

Keep your worksite safe and clutter free—this coiled polyurethane rubber tubing extends when you need it and retracts out of the way when you don’t. The material is ether based, so you’ll get the abrasion and tear resistance you’d expect from polyurethane, along with the ability to use it in humid environments. Tubing is flexible and bends easily around objects. It comes in multiple colors, so you can color-code your lines.

Clear tubing allows you to easily monitor flow. It has a colored tint. Opaque tubing doesn’t allow you to see what’s flowing through the line.

Note: Length refers to the length you can extend the tubing. Overstretching can cause the tubing to lose its ability to fully retract back to its normal state. Retracted length refers to the length of the tubing when coiled.

Joined Firm Rubber Tubing for Air and Water

Opaque

Clear and Opaque

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.

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.
