Each section covers a 1-1\/8 inch pipe diameter with a 3\/8 inch wall thickness and a 6-foot length. Licensed HVAC technicians and mechanical insulation installers use this product on refrigerant suction lines, chilled-water piping, and other low-temperature applications where moisture infiltration is a primary concern. The closed-cell structure resists moisture vapor transmission, keeping the insulation thermally effective over the life of the system.\u003c\/p\u003e\n\u003cp\u003eThis insulation section is suited for residential and commercial mechanical piping installations, including refrigeration lines, chilled-water distribution, and hydronic systems where condensation control is critical. Schools, hospitals, government buildings, and commercial facilities specify AP Armaflex for long-term performance on exposed and concealed piping. Its moisture-resistant construction is particularly effective where fibrous insulations would otherwise absorb condensation, degrade thermally, and become susceptible to fungal growth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-cell foam construction resists moisture vapor transmission and prevents condensation on cold piping\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch inner diameter fits standard copper and ACR tubing of matching outside diameter\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch wall thickness provides thermal protection on refrigerant and chilled-water lines\u003c\/li\u003e\n  \u003cli\u003e6-foot section length simplifies measuring and cutting during installation\u003c\/li\u003e\n  \u003cli\u003eMaintains physical and thermal integrity over the service life of the mechanical system\u003c\/li\u003e\n  \u003cli\u003eInhibits conditions that lead to mold and fungal growth on piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation insulation for mechanical piping with a 1-1\/8 inch outside diameter, commonly found in refrigeration, chilled-water, and HVAC suction-line applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or certified mechanical insulation contractors in accordance with local mechanical codes and ASHRAE insulation guidelines. De-energize and isolate the piping system and allow it to reach ambient temperature before applying insulation. Slit the foam lengthwise to slip it over existing piping, or thread over new piping before connections are made. Use manufacturer-approved contact adhesive at all seams and butt joints to maintain a continuous vapor barrier.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Inner Diameter\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSection Length\u003c\/strong\u003e: 72 inches (6 feet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H)\u003c\/strong\u003e: 72 x 1.88 x 1.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Closed-cell elastomeric foam\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: 11838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51343676309810,"sku":"11838","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/DSAnonDownloadServlet_e24d73a7-48cc-4707-927d-5385dae7d82f.jpg?v=1782023788","url":"https:\/\/voomisupply.com\/products\/armacell-11838-armaflex-ac-pipe-insulation-1-1-8-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
