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.

Odor-Resistant Soft Rubber Tubing for Food and Beverage

Flexible
Compatible with Barbed Tube Fittings
Soft (Durometer 50A)
Temperature Range: -60° to 400° F

Silver ions are blended into the walls of this silicone tubing to inhibit the growth of odor-causing microbes. Tubing is suitable for food and beverage applications. Free of plasticizers like DEHP, it won’t impart tastes to the fluid passing through it. Tubing is semi-clear, so you get a limited view of what's flowing through the line. It is flexible, so it bends easily around objects.

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.

Hollow Linear Motion Shafts

Shown with Bearing and Wiring (Not Included)

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center. Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. Shafts are case-hardened to increase hardness and wear resistance. Interior is unfinished; exterior is turned, ground, and polished to tight diameter and straightness tolerances. All are chamfered to remove sharp edges and reduce damage to bearings, housings, and other components during installation.
