It measures 2-5\/8 inches inner diameter with a 3\/8-inch wall thickness and comes in a 6-foot length. The closed-cell structure limits moisture absorption and maintains thermal performance across a wide temperature range, from -297 degrees F minimum to 180 degrees F maximum. The split design allows installation over existing pipe runs without cutting or disconnecting lines. Licensed plumbing and HVAC technicians are the primary installers of this product type.\u003c\/p\u003e\n\u003cp\u003eThis pipe insulation is suited for domestic plumbing lines and residential heating systems. The 2-5\/8-inch inner diameter is sized for 2-1\/2-inch CTS pipe with a 2-5\/8-inch OD. Its black color, flame spread rating of 25, and smoke rating of 50 meet commonly required fire and smoke standards for building installations. It is packaged 12 tubes per carton at approximately 9 pounds per carton, making it practical for multi-unit or whole-system installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-cell polyolefin\/polyethylene construction limits moisture ingress and maintains insulation value\u003c\/li\u003e\n  \u003cli\u003eSplit design enables installation over existing pipe without line disconnection\u003c\/li\u003e\n  \u003cli\u003eTemperature rated from -297 degrees F to 180 degrees F for broad application coverage\u003c\/li\u003e\n  \u003cli\u003eFlame spread rating of 25 and smoke rating of 50 per ASTM E 84\u003c\/li\u003e\n  \u003cli\u003eSelf-sealing feature streamlines installation and reduces the need for additional adhesive\u003c\/li\u003e\n  \u003cli\u003e12 tubes per carton at 9 pounds per carton for efficient jobsite handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSized for 2-1\/2-inch CTS pipe with a 2-5\/8-inch OD.

Before installing pipe insulation on any active line, shut off and depressurize the system and allow pipes to reach ambient temperature. Open the split seam, wrap around the pipe, and press the self-sealing edges together firmly for a secure closure. Follow all applicable local plumbing and mechanical codes, including ASTM C 1427 requirements referenced by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cellular polyolefin\/polyethylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size Compatibility\u003c\/strong\u003e: 2-1\/2 inch CTS, 2-5\/8 inch OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature Rating\u003c\/strong\u003e: -297 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature Rating\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame Spread Rating\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmoke Rating\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCell Structure\u003c\/strong\u003e: Closed cell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging Quantity\u003c\/strong\u003e: 12 tubes per carton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging Weight\u003c\/strong\u003e: 9 pounds per carton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ASTM C 1427, ASTM C 177\/ASTM C 518, ASTM E 96, ASTM E 84, MEA 6-02-M\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: NOMACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DGS25838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NOMACO","offers":[{"title":"Default Title","offer_id":51306619404594,"sku":"DGS25838","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309548839.jpg?v=1781293385","url":"https:\/\/voomisupply.com\/products\/nomaco-dgs25838-pipe-insulation-split-2-5-8-in-3-8-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
