Abrasion-Resistant Firm Rubber Tubing for Air and Water

Neoprene Rubber Tubing

With excellent resistance to abrasion and tearing, this rubber tubing can hold up in rugged environments. It is semi-flexible, so it is good for gradual bends.

Neoprene tubing can handle higher temperatures than polyurethane tubing. It meets ASTM E162 specifications for surface flammability. Tubing is opaque, so you cannot see what’s running through the line.

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.

Tubing that meets NSF/ANSI 51 is safe for contact with food and beverage.
