4 1/4" Tubing | McMaster-Carr

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).

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.

Clear Scratch- and UV-Resistant Cast Acrylic Tubes

Color: Clear
Temperature Range: 0° to 150° F
Tensile Strength: 10,000-11,250 psi (Good)
Impact Strength: 0.3-0.4 ft.-lbs./in. (Poor)
Hardness: Rockwell M94-M100 (Hard)
For Use Outdoors: Yes
Specifications Met: See table

Fabricate containers, tanks, and lenses for light fixtures with these scratch- and UV-resistant cast acrylic tubes. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material stands up to outdoor use better than polycarbonate and maintains clarity over time.

Hook-and-Loop Wrap-Around
Sleeving for Universal Robots

Organize and protect the cables and tubing on your Universal Robots arm without hindering its movement. This sleeving is made for Universal Robots arms, so you don’t need to measure, cut, or customize for a good fit. The hook-and-loop closure makes installation quick, and unlike cable ties, it’s easy to detach and adjust. Cables run through a separate channel, so you can access them without removing the sleeving from your arm. Made from polyurethane, this sleeving is flexible enough for cables and tubing to move easily, and durable enough to withstand continuous movement. It’s also lighter than hose carriers and conduit, so it won’t weigh down your robot arm. Each includes two pieces of sleeving.
