5 3/4" Tubing | McMaster-Carr

Polycarbonate tubing won’t degrade when exposed to the damaging effects of ultraviolet light. It should be used at temperatures above freezing. Tubing is clear, so you can easily monitor flow. It is rigid and does not bend.

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.

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.

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.

Oversized Round Tubes

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.
