Large-Diameter Soft Rubber
Tubing for Food and Beverage
With a diameter of 2" or larger, this tubing has the girth to handle high-volume beverage and bulk food processing applications. It has excellent abrasion and tear resistance. Tubing is made of FDA listed materials. It doesn’t contain plasticizers like DEHP, so it won’t impart tastes or odors to the product passing through it. Tubing is opaque, so you cannot see inside the line to monitor flow.
Tubing connects to fittings with a worm-drive clamp (sold separately).
Gum rubber tubing holds up under lower temperatures than neoprene rubber tubing. It is best suited for dry foods. Tubing is flexible, so it bends easily around objects.
High-Temperature Rigid Metal Duct Hose for Fumes
- Rigid
- Compatible Clamps: U-Bolt Clamps
- Max. Temperature: Galvanized Steel: 550° F; Aluminum: 450° F; 304 and 316 Stainless Steel: 1000° F
Metal interlocked strips create a rigid, durable hose that stays strong under high temperatures. Hose is for use with smoke, welding fumes, and oil fumes.
Galvanized steel offers fair corrosion resistance.
Aluminum is lighter than steel and has good corrosion resistance.
304 stainless steel has very good corrosion resistance.

Bend-and-Stay Metal Duct Hose for Air
- Very Flexible
- Compatible Clamps: Worm-Drive Clamps
- Temperature Range: -100° to 435° F
Unlike fabric duct hose, this lightweight aluminum hose can bend around corners and hold its shape. Hose is not for continuous flexing. One end of the hose is crimped; insert the crimped end into another piece of duct hose and secure with a clamp to create longer lengths. The hose may need support once the length exceeds 6 feet.

- Specifications Met: See table
The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.
Multipurpose 304 Stainless Steel
From cookware to chemical-processing equipment, 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.
304/304L stainless steel contains less carbon than standard 304 for better weldability.
Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.
