Product SpecsDescriptionEPCO's T8 UV Filtering Tube Guards provide the basic reduction of harmful UV energy by filtering 99.9% of harmful UV rays up to 390 nanometers*.

Special UV additive filters UV rays better than acrylic materials with comparable wall thickness (0.016" wall thickness). Minimizes premature color shifting (fading) and deterioration that can be detrimental to food products, paper, natural and synthetic textiles, paints, coatings, woods and polymer materials, inc. Provides years of protection from dangerous UV light. Can readily be "field-cut" to length if desired. Manufactured to the highest quality standards. Sizes: T5, T8 and T12.
