It fits 4-inch IPS pipe with a 4.5-inch inside diameter and a 0.75-inch wall thickness, delivering an R-value of 4.8. The closed-cell foam structure resists water vapor transmission at 0.08 perm-in and limits water absorption to 0.2 percent, keeping thermal performance intact over the life of the system. Each section runs 6 feet in length. Licensed HVAC technicians, pipefitters, and mechanical insulation contractors install this product on new construction and retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThe apt40034r is suited for a wide range of mechanical piping applications including chilled water lines, refrigeration piping, hot and cold domestic water lines, and HVAC systems. Its moisture resistance makes it particularly effective on chilled water and refrigeration circuits where condensation would otherwise saturate fibrous insulation, degrade thermal performance, and promote fungal growth. It is also appropriate for exposed ceiling runs, air plenums, industrial mechanical rooms, and exterior installations. Schools, hospitals, universities, government buildings, and commercial facilities commonly specify this product for long-term system integrity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-cell elastomeric foam construction blocks moisture infiltration and resists condensation buildup\u003c\/li\u003e\n  \u003cli\u003eR-value of 4.8 with thermal conductivity of 0.235 to 0.268 Btu-in\/hr-sq-ft-degrees F\u003c\/li\u003e\n  \u003cli\u003eWater vapor permeability of 0.08 perm-in and water absorption of 0.2 percent\u003c\/li\u003e\n  \u003cli\u003eFlame Spread Index of 25 and Smoke Developed Index of 50 for fire-rated assembly applications\u003c\/li\u003e\n  \u003cli\u003eTemperature rating from -297 to 220 degrees F covers refrigeration and hot water service\u003c\/li\u003e\n  \u003cli\u003e6-foot section length with 4.5-inch ID fits standard 4-inch IPS pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 4-inch IPS (iron pipe size) mechanical piping in refrigeration, chilled water, hot water, and HVAC applications in residential, commercial, and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed mechanical insulation contractors, pipefitters, or HVAC technicians following local mechanical codes and manufacturer guidelines. Shut down and depressurize the piping system before applying insulation on live or pressurized lines where required by site safety procedures. Seams and butt joints should be sealed with a compatible elastomeric adhesive to maintain vapor barrier continuity. On exterior applications, a protective jacketing or coating may be required to protect against UV degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Elastomeric Foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Closed Cell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIron Pipe Size\u003c\/strong\u003e: 4 inches IPS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R4.8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Conductivity\u003c\/strong\u003e: 0.235 to 0.268 Btu-in\/hr-sq-ft-degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -297 to 220 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Vapor Permeability\u003c\/strong\u003e: 0.08 perm-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Absorption\u003c\/strong\u003e: 0.2 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame Spread Index\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmoke Developed Index\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity\u003c\/strong\u003e: 3 to 6 cu-ft\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\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: apt40034r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51138391736626,"sku":"APT40034R","price":15.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531164.jpg?v=1778255088","url":"https:\/\/voomisupply.com\/products\/armacell-apt40034r-ap-armaflex-pipe-cover-4in-ips","provider":"Voomi Supply","version":"1.0","type":"link"}
