Plastic-Craft | Polycarbonate Round Tube, Clear, 3-3/4" (3.75") ID x 4" OD x 48" L

COMMON QUESTIONS: Q: Is polycarbonate actually shatterproof? A: Yes — polycarbonate delivers 250x the impact resistance of glass with 16 ft-lb/in notched impact strength. It will not shatter under normal impact loads — the standard choice for machine guards, safety shields, and bullet-resistant barriers. Q: Will polycarbonate work for a machine guard or safety shield? A: Yes — polycarbonate is the industry standard for machine guards, safety shields, and protective barriers precisely because of its combination of optical clarity and near-unbreakable toughness. Rated UL 94 V-2 flame resistant. Q: Is polycarbonate UV stable for greenhouse or outdoor use? A: Standard polycarbonate provides moderate UV resistance but can yellow over time with prolonged direct sun exposure. For greenhouse panels and long-term outdoor use, specify a UV-coated or UV-stabilized grade for maximum longevity. This 3-3/4" ID x 4" OD x 48" clear polycarbonate tube is built for applications where glass simply isn't an option. With 9,500 PSI tensile strength, a service range of -40°F to 280°F, and UL 94 V-2 flame rating, it delivers the structural reliability and optical clarity that engineers and fabricators depend on. Stocked and ships from West Nyack, NY. Ideal for machine guards, safety shields, light covers, display columns, pneumatic housings, and industrial enclosures, this tube performs across manufacturing, aerospace, robotics, and greenhouse environments. Its ASTM D3935 compliance makes it a trusted specification material for demanding structural and protective applications. Polycarbonate cuts cleanly with standard woodworking or metalworking tools, bonds well with compatible adhesives, and machines with excellent dimensional stability. Avoid sharp inside bend radii without thermoforming — cold bending this wall thickness is not recommended. Plastic-Craft Products has been a trusted supplier of quality plastic materials since 1934. We are ISO 9001:2015 and AS9100D certified,
