Insul-Tube® 6'L, 3/4" Wall Thickness, 2" Nom.I.D.INSUL-TUBE® is used to retard heat gain and prevent condensation or frost formation on refrigerant lines, cold water plumbing, and chilled water systemsIt also retards heat flow for hot water plumbing, liquid heating, dual temperature piping, and many solar systemsDesigned for the HVAC and Refrigeration industryINSUL-TUBE® is non-porous, non-fibrous and resists mold growth. INSUL-TUBE® Pipe Insulation is made from a UV resistant elastomeric blendFor moderate UV exposure, no additional protective coating is neededHowever, for severe UV exposure (rooftop applications) or where optimum performance is required, 374 Protective Coating or approved jacketing or cladding should be used.SPECIFICATION COMPLIANCE ASTM C 534 Type 1 (Tubing) Grade 1, ASTM D 1056-00-2C1 New York City MEA 186-86-M VolIV USDA RequirementsUL 94-5V Flammability Classification (Recognition No.E300774) ASTM E 84 2" 25/50-tested according to UL 723 and NFPA 255 Complies with requirements of CAN/ULC S102 03FMRC Approval Guide Chapter 14 Pipe InsulationNFPA No.101 Class A RatingMeets requirements of NFPA 90A Sect2.3.3 for Supplementary Materials for Air Distribution SystemsMeets requirements of ASTM C 411 (Test Method for Hot Surface Performance of High Temperature Thermal Insulation)Meets requirements of UL 181 sections 11.0 and 16.0 (Mold Growth/Air Erosion) Sold in package quantity of 11, priced each.
