Built from a fiber-free, formaldehyde-free nitrile and PVC compound, it meets the indoor air quality demands of commercial and residential HVAC and refrigeration installations. The closed-cell structure functions as a built-in vapor retarder, eliminating the need for a separate vapor barrier wrap. It carries a 25\/50 flame-spread and smoke-developed rating and an R-value of R3.1, making it approved for use in air plenums with wall thicknesses up to 2 inches.\u003c\/p\u003e\u003cp\u003eThis insulation tube is suited for HVAC refrigeration systems where condensation control and indoor air quality are critical requirements. The 1-3\/8 inch nominal inside diameter and 1\/2 inch wall thickness fit standard refrigerant suction lines and chilled-water supply piping in both residential and light commercial environments. Each piece is 72 inches (6 feet) long. Microban antimicrobial product protection is integrated into the material to resist mold growth over the life of the installation. The low-VOC, non-particulating formulation makes it appropriate for use in occupied spaces and plenum-rated applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed-cell nitrile and PVC construction provides built-in vapor retardant barrier — no separate vapor wrap required\u003c\/li\u003e\n\u003cli\u003eFiber-free, formaldehyde-free, low-VOC, non-particulating formula protects indoor air quality\u003c\/li\u003e\n\u003cli\u003eMicroban antimicrobial protection integrated into the insulation material for lasting mold resistance\u003c\/li\u003e\n\u003cli\u003e25\/50 flame-spread and smoke-developed rating approved for air plenum installations up to 2 inch wall thickness\u003c\/li\u003e\n\u003cli\u003eR-value of R3.1 for effective thermal performance on refrigerant and chilled-water lines\u003c\/li\u003e\n\u003cli\u003eRated for service temperatures from -297 degrees F to 220 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style elastomeric pipe insulation for HVAC and refrigeration suction lines with a 1-3\/8 inch nominal inside diameter, commonly found in residential and light commercial refrigerant piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstalled by licensed HVAC and refrigeration technicians. Shut down the refrigeration or HVAC system and allow piping to return to ambient temperature before applying insulation. Joints and seams should be sealed with compatible elastomeric adhesive to maintain vapor retarder continuity. Installation in plenum spaces must comply with local mechanical codes and applicable ASHRAE guidelines regarding flame-spread ratings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Nominal Inside Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 72 inches (6 feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R3.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -297 degrees F to 220 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame\/Smoke Rating\u003c\/strong\u003e: 25\/50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition\u003c\/strong\u003e: Nitrile, PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV Resistant\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.84 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProp 65\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARMACELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: apt13812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51620137795890,"sku":"APT13812","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc0664a7c7146f79f470752a77f4920e_c7df5c98-a946-47e9-973e-37ffa73268d3.jpg?v=1787340896","url":"https:\/\/voomisupply.com\/products\/armacell-apt13812-pipe-insulation-1-3-8in-id-1-2in-wall-6ft","provider":"Voomi Supply","version":"1.0","type":"link"}
