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.
Mineral Wool Pipe Insulation
These insulation tubes and sheets meet ASTM E84 standards for flame and smoke. They are typically used in process piping and mechanical systems and perform best at temperatures up to 600° F. To use outdoors, add metal jacketing.

- Temperature Range: 0° to 1200° F
- Heat Flow Rate: 0.23 Btu @ 75° F
- Density: 8 lbs./cu. ft.
- Color: Yellow
- Specifications Met: See table

Fiberglass Pipe Insulation
This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.
Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.
Tubes have an all-service jacket (ASJ) made of kraft paper with an adhesive strip closure. Seal with reinforced insulation tape (sold separately).

- Temperature Range: 0° to 850° F
- Jacket Temperature Range: -20° to 150° F
- Heat Flow Rate: 0.23 Btu @ 75° F
- Density: 4.5 lbs./cu. ft.
- Color: Yellow
- Jacket Color: White
- Specifications Met: ASTM E84 25/50 for Flame and Smoke, ASTM C547, ASTM C585

- Temperature Range: 0° to 1000° F
- Heat Flow Rate: 0.23 Btu @ 75° F
- Density: 5 lbs./cu. ft.
- Color: Brown
- Specifications Met: ASTM E84 25/50 for Flame and Smoke, ASTM C585
Strut-Mount Vibration-Damping Routing Clamps
Slide multiple clamps into existing strut channel to organize lines of pipe, tubing, and conduit without the need for drilling, welding, or using adhesive. Clamps have a plastic or rubber cushion or body to reduce vibration.
Zinc-plated steel and stainless steel clamps with TPE cushion resist most oils, chemicals, and cleaning compounds. With a metal body, they provide a more secure hold than TPE clamps. Slide into strut channel and fasten the nut to secure. Stainless steel clamps are more corrosion resistant than zinc-plated steel clamps.

Strut-Mount Metal Routing Clamps


Route pipe, tubing, and conduit across strut channel. To install, slide the clamp into the strut channel and tighten the clamping screw to secure.
Zinc-plated steel clamps have good corrosion resistance. Copper-plated steel clamps resist corrosion when used with copper tubing. PVC-coated steel clamps have mild corrosion resistance and are compatible with PVC pipe and conduit. 304 stainless steel clamps have excellent corrosion resistance and good chemical resistance. 316 stainless steel clamps have excellent corrosion and chemical resistance.
