Static-Control Soft Plastic and Rubber Tubing for Air and Water

Protect sensitive equipment with this tubing—it is specially formulated to reduce the buildup of static electricity.

Silicone rubber tubing has carbon embedded into the walls to divert static quickly. It can handle a wider temperature range than PVC tubing, and is more flexible, so it bends easily around objects. It is opaque, so you can’t see what’s flowing through the line.

High-Temperature Soft Rubber Tubing for Food and Beverage

Hot food and beverage applications won’t harm this silicone tubing. It is made of FDA listed materials. Tubing is made without plasticizers like DEHP, so it won’t impart tastes or odors to the fluid passing through it. It can handle applications requiring repeated bending and flexing, such as metering (peristaltic) pumps and robotics. It is flexible and bends easily around objects.

Opaque tubing blocks your view, so you cannot see inside the line to monitor flow.

Polished Multipurpose 304 Stainless Steel

Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The sheets, strips, bars, and adhesive-back foil are covered with a protective peel-off film. 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

Brushed #4 is often called a satin finish; it’s similar to a #3 finish, except the grain lines are finer. Rectangular and round tubes are polished on the outside.

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.
