It combines a thick fiberglass insulation blanket core with a reinforced metalized polyester vapor barrier jacket to limit thermal loss and control condensation on chilled and hot piping systems. Each section covers 4 inches in diameter and ships in a 5-foot length, reducing the need for field cutting. The sleeve is rated for temperatures from -20 degrees F up to 250 degrees F and meets UL 181B standards. HVAC technicians and mechanical contractors install this product during new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is intended for indoor HVAC system piping, including supply and return lines where thermal efficiency and vapor control are required. The 5-foot pre-cut section length streamlines installation compared to bulk duct wrap, reducing both labor time and on-site material waste. A starter cap is included with the product to provide a clean termination at pipe ends. It is suited for residential and light commercial mechanical systems where UL 181B-listed insulation materials are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR4.2 thermal resistance rating for effective energy retention on HVAC piping\u003c\/li\u003e\n  \u003cli\u003eReinforced metalized polyester vapor barrier jacket controls moisture and condensation\u003c\/li\u003e\n  \u003cli\u003ePre-cut 5-foot sections reduce in-shop and jobsite cutting time\u003c\/li\u003e\n  \u003cli\u003eFlat blanket design fits 4-inch diameter pipe without custom fabrication\u003c\/li\u003e\n  \u003cli\u003eStarter cap included for clean pipe-end terminations\u003c\/li\u003e\n  \u003cli\u003eUL 181B listed for use in HVAC duct and pipe insulation systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style insulation solution for 4-inch diameter indoor HVAC system piping where UL 181B-listed flat blanket pipe insulation sleeves are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or mechanical contractors following local mechanical codes and manufacturer guidelines. Shut down and de-energize the HVAC system and allow piping to reach ambient temperature before applying insulation. Wrap the fiberglass blanket snugly around the pipe and secure the vapor barrier jacket seams per UL 181B requirements, using appropriate UL-listed tape or fasteners. Do not compress the fiberglass core excessively, as compression reduces the effective R-value.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R4.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature Rating\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature Rating\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Fiberglass Blanket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Reinforced Metalized Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Flat Blanket Sleeve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Indoor HVAC System\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Starter Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: UL 181B\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: ATCO RUBBER PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 010-R4.2_4X5FT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATCO RUBBER PRODUCTS","offers":[{"title":"Default Title","offer_id":51283944374578,"sku":"010-R4.2_4X5FT","price":18.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276855.jpg?v=1781063835","url":"https:\/\/voomisupply.com\/products\/atco-rubber-products-010-r4-2_4x5ft-pipe-insulation-sleeve-r4-2","provider":"Voomi Supply","version":"1.0","type":"link"}
