High-Temperature Abrasion-Resistant Soft
Rubber Tubing for Food, Beverage, and Dairy

Flexible
Compatible with Barbed Tube Fittings
Soft (Durometer 65A)
Temperature Range: -60° to 450° F

Not only can this tubing handle the highest temperatures of all our soft tubing for food, beverage, and dairy, it also has thick, silicone rubber walls for superior abrasion and crush resistance. Tubing is made of FDA listed materials. Free of plasticizers like DEHP, it won’t impart tastes or odors to the fluid passing through it. Tubing is semi-clear, so you get a limited view inside the line. It is flexible, so it bends easily around objects.

Abrasion-Resistant Soft Rubber Tubing for Fuel

Semi-Clear Blue

Flexible
Compatible with Barbed Tube Fittings
Soft (Durometer 70A)
Temperature Range: -40° to 180° F

This polyurethane tubing is soft enough to handle continuous bending and flexing, yet tough enough to resist tearing and abrasion. Use it in applications requiring movement, such as metering (peristaltic) pumps and robotics. Tubing is semi-clear, so you get a limited view inside the line.

High-Polish Stainless Steel Tubing for Food, Beverage, and Dairy

The interior and exterior are polished to a high-luster finish to resist particle buildup and allow for easy cleaning. Tubing is welded with a smoothed weld bead on the inside.

304/304L stainless steel tubing has very good corrosion resistance. Tubing that meets DIN 11850 and DIN EN 10357 complies with international standards for food industry stainless steel tubing.

Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

Ultra-High-Temperature Quartz Glass Tubes

Color: Clear
Max. Temperature: 2000° F
Fabrication: Annealed

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack. Even tougher than borosilicate, they can be used in furnaces and ovens heated up to 2000° F. These highly pure tubes are often used in laboratories because they won’t leach impurities into samples or contaminate chemical reactions. Quartz tubes are optically clear and have excellent UV transmission, making them ideal for UV purification systems.
