Rated for a temperature range of -297 to 220 degrees F and delivering an R-value of R3.2, it provides reliable thermal performance in both hot and cold pipe service. The insulation fits a 2-inch nominal pipe size with a 2-1\/8-inch inner diameter and features 1\/2-inch wall thickness. The low-profile, wide lap seal keeps the longitudinal seam closed securely without requiring additional adhesive, reducing labor time on standard and hard-to-reach installations.\u003c\/p\u003e\n\u003cp\u003eThis tube insulation is suited for residential and light commercial mechanical systems where quick field application is a priority. The reinforced lap seal with an easy-release liner tab allows installers to position and seal the insulation without extra prep steps. It is commonly installed on chilled water lines, refrigerant suction lines, domestic cold water piping, and similar applications where condensation control and thermal efficiency are required. Each section is 6 feet in length, supporting efficient coverage on straight pipe runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReinforced wide lap seal with easy-release liner tab for fast, secure longitudinal seam closure\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch wall thickness provides R3.2 thermal resistance\u003c\/li\u003e\n  \u003cli\u003eTemperature-rated from -297 to 220 degrees F, covering a broad range of mechanical piping service conditions\u003c\/li\u003e\n  \u003cli\u003eNBR\/PVC elastomeric foam construction resists moisture absorption and vapor transmission\u003c\/li\u003e\n  \u003cli\u003eBlack finish requires no additional jacketing for exposed indoor installations\u003c\/li\u003e\n  \u003cli\u003e6-foot lengths minimize field cuts on standard pipe runs\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 sleeve for 2-inch nominal pipe in residential and commercial HVAC, plumbing, and refrigeration systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstalled by HVAC technicians, pipefitters, and plumbers as part of mechanical insulation work. Shut down and depressurize the pipe system and allow it to reach ambient temperature before applying insulation. Peel the liner tab and press the lap seal firmly along the full length of the seam to ensure a continuous, gap-free closure. Where end joints or fittings require additional sealing, use a compatible elastomeric foam adhesive in accordance with the manufacturer guidelines and local mechanical code requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 2-1\/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\u003eR-Value\u003c\/strong\u003e: R3.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -297 to 220 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Elastomeric Foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: NBR\/PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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-BST21812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51383635804466,"sku":"ARMA-BST21812","price":50.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/armacell_BST35812.jpg?v=1782602708","url":"https:\/\/voomisupply.com\/products\/armacell-arma-bst21812-foam-tube-insulation-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
