It features a 1-1\/8 inch inner diameter with a 1\/2 inch wall thickness and comes in 6-foot lengths. The closed-cell structure provides a built-in vapor retardant barrier, eliminating the need for a separate vapor retarder wrap. The formulation is fiber-free, formaldehyde-free, and low-VOC, which protects indoor air quality in occupied and sensitive environments. Microban antimicrobial protection is integrated into the material to resist mold growth.\u003c\/p\u003e\n\u003cp\u003eAP Armaflex is suited for residential and commercial HVAC and refrigeration piping in environments that demand high-level condensation control and strict indoor air quality standards. Typical applications include refrigerant suction lines, chilled water piping, and other cold-surface piping where surface temperatures fall below the dew point. The 25\/50 flame spread and smoke developed rating qualifies this product for installation in air plenums with wall thicknesses up to 2 inches, making it appropriate for above-ceiling and air-handling unit installations where plenum-rated materials are required by code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-cell structure provides excellent condensation control without additional vapor retarder\u003c\/li\u003e\n  \u003cli\u003eFiber-free, formaldehyde-free, and low-VOC formulation protects indoor air quality\u003c\/li\u003e\n  \u003cli\u003eMicroban antimicrobial protection integrated throughout the material for mold resistance\u003c\/li\u003e\n  \u003cli\u003e25\/50 flame spread and smoke developed rating approved for use in air plenums up to 2 inch wall thickness\u003c\/li\u003e\n  \u003cli\u003eFlexible elastomeric construction allows installation on straight runs and moderate bends\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style insulation solution for copper and other metallic refrigerant and chilled water piping with a 1-1\/8 inch outer diameter in residential and commercial HVAC and refrigeration systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed HVAC technicians and pipefitters typically install elastomeric pipe insulation on refrigerant and chilled water lines. Shut down and depressurize the system before working on any connected piping. Butt joints and seams must be fully adhered with a compatible elastomeric insulation adhesive to maintain the vapor retardant barrier. Follow local mechanical codes and manufacturer adhesive instructions for plenum-rated installations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 1-1\/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: 6 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Flexible closed-cell elastomeric foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame and Smoke Rating\u003c\/strong\u003e: 25\/50 (plenum rated up to 2 inch wall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAntimicrobial\u003c\/strong\u003e: Microban integrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVOC\u003c\/strong\u003e: Low-VOC formulation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFiber Content\u003c\/strong\u003e: Fiber-free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFormaldehyde\u003c\/strong\u003e: Formaldehyde-free\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: ARMA-APT11812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51524869390642,"sku":"ARMA-APT11812","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69b64b1e9d133969322883537899db51_9efd22d2-9717-4d8f-86ff-d576bc924b4f.webp?v=1785460160","url":"https:\/\/voomisupply.com\/products\/armacell-arma-apt11812-pipe-insulation-1-1-8-in-1-2-in-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
