Chemical-Resistant PVC Tubes

When working near chemicals such as acids and alkalies, these tubes offer 360° protection to wires, cords, and anything that can slide through them. They’re made of PVC Type 1, a material that’s easy to thermoform, plus it is an excellent insulator. These tubes are oversized on the outside and undersized on the inside to allow for finishing to the sizes listed.

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
Specifications Met: Made of FDA Listed Material, UL 94HB

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.

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 94HB

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.
