About Duct Hose

About Plastic and Rubber Tubing

Flexible
Firm (Durometer 80A)
Temperature Range: -40° to 190° F

Sized for vibrating sifters, screeners, hoppers, and packaging equipment, this tubing has a diameter of 4" or larger to handle a variety of bulk food processing applications. It is made of FDA listed materials. Free of plasticizers like DEHP, it won’t impart tastes or odors to the product passing through it. Tubing is polyurethane for excellent resistance to abrasion and tearing. The tubing material is ether based, so the tubing won’t degrade in humid environments. Tubing is clear, so you can see inside the line to monitor flow. It is flexible and bends easily around objects.

Tubing connects to fittings with a worm-drive clamp (sold separately).
