Abrasion-Resistant Hard Rubber Tubing for Air and Water
- Semi-Flexible
- Compatible with Push to Connect Tube Fittings
- Hard (Durometer 50D)
- Temperature Range: -30° to 140° F
With excellent resistance to abrasion and tearing, this polyurethane tubing can hold up in rugged environments. The material is ether based, so it stays strong and durable even when exposed to water. Semi-flexible, it’s good for gradual bends.
Opaque tubing blocks your view, so you can’t see inside your line.

Choose-a-Color Firm Plastic and Rubber Tubing for Air and Water
Multiple colors allow you to color-code your line for easy identification. Tubing is flexible, so it bends easily around objects.
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.

Self-Retracting Firm Rubber Tubing for Air and Water
- Flexible
- Compatible with Barbed Tube Fittings
- Firm (Durometer 95A)
- Temperature Range: -40° to 120° F
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
- 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. Opaque tubing does not let you see inside the line.

Weld-Spatter-Resistant Firm Rubber Tubing for Air and Water
- Semi-Flexible
- Compatible with Push to Connect Tube Fittings
- Hardness:
Inch: Firm (Durometer 95A)
Metric: Firm (Durometer 90A) - Temperature Range:
Inch: -40° to 165° F
Metric: 0° to 140° F
Designed for use in welding applications, this tubing is specially formulated to self-extinguish. It’s made of ether-based polyurethane, so it has excellent resistance to abrasion and tearing and stays strong and durable in humid environments. Tubing is opaque, so you cannot see what is flowing through the line. It is semi-flexible, which is good for gradual bends.
To attach fittings, use a cutting tool (sold separately) to strip away the outer layers of tubing. The tube OD dimension refers to the inner layer of tubing. Attach a protective cover (sold separately) to prevent weld spatter from getting between the tubing and fitting.
Inch tubing has two layers of material. It meets UL 94 V-0 for better flame retardance than metric tubing. It can handle higher pressures and a wider temperature range than metric tubing.

Soft Plastic Tubing for Air and Water
This general purpose PVC tubing is the industry standard for air and water applications. Tubing is clear, so you can easily monitor flow. It is flexible to easily bend around objects.
Masterkleer tubing is more economical than Tygon tubing. Tygon tubing has a nonabsorbing surface for improved flow and drainage.
