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.

Clear Scratch- and UV-Resistant Acrylic Tubes
- Color: Clear
- Temperature Range: -40° to 180° F
- Tensile Strength; 9,195-11,030 (Good)
- Impact Strength: 0.040 ft.-lbs./in.
- Hardness: Rockwell M89-M96 (Hard)
- For Use Outdoors: Yes
- Specifications Met: UL 94 HB
When compared to cast acrylic tubes, these extruded acrylic tubes offer nearly the same performance at a fraction of the cost. Use them for sight gauges and protective covers. This scratch- and UV-resistant material stands up to outdoor use better than polycarbonate and maintains clarity over time.

Clear Impact-Resistant Polycarbonate Tubes
- Color: Clear
- Temperature Range: -40° to 200° F
- Tensile Strength: 8,900-9,500 psi (Good)
- Impact Strength: 12-18 ft.-lbs./in. (Excellent)
- Hardness: Rockwell R118 (Hard)
- For Use Outdoors: No
Comparable to Lexan, Hyzod, Tuffak, and Makrolon, these polycarbonate tubes are half the weight of glass and maintain excellent impact resistance across a wide temperature range. Use them to make instrument gauge covers and display racks.
Slippery UHMW Polyethylene Tubes
These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.
Tubes with an oversized OD also have an undersized ID for finishing to the sizes listed.
- Color: White
- Temperature Range: -20° to 180° F
- Tensile Strength: 4,350-5,800 psi (Poor)
- Impact Strength: 16.8 ft.-lbs./in. (Excellent)
- Hardness: Durometer 65D-67D (Medium)
- For Use Outdoors: No
- Specifications Met: ASTM D4020, FDA Compliant 21 CFR 177.1520, UL 94 HB
Flexible Rubber Foam Pipe Insulation
Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines. Seal with contact adhesive (sold separately). To use outdoors, coat in acrylic paint.
