It features a 2:1 shrink ratio, starting at 0.125 inches inner diameter and shrinking down to 0.062 inches after heat is applied. The sleeve ships as a single 8-foot length and weighs 0.01 pounds. Activation begins at 248 degrees F. The polyolefin construction provides corrosion resistance, fluid resistance, and fungus resistance, making it a practical choice for conduit, terminal, and connector work across electrical, HVAC control wiring, and low-voltage applications.\u003c\/p\u003e\u003cp\u003eThis sleeve is suited for electrical contractors, HVAC technicians, and plumbers who need reliable insulation and strain relief on wire splices, terminals, and connectors. It performs across a wide temperature range, rated from -67 degrees F to 275 degrees F, which covers most residential and light commercial environments. The black finish is standard for general-purpose wiring work. Each unit is sold as one 8-foot length, which can be cut to length in the field as needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2:1 shrink ratio — 0.125 inches ID before shrinking, 0.062 inches ID after shrinking\u003c\/li\u003e\n\u003cli\u003e8-foot overall length, field-cuttable to any shorter dimension\u003c\/li\u003e\n\u003cli\u003ePolyolefin material rated corrosion-resistant, fluid-resistant, and fungus-resistant\u003c\/li\u003e\n\u003cli\u003eShrink activation temperature of 248 degrees F\u003c\/li\u003e\n\u003cli\u003eOperating range of -67 degrees F to 275 degrees F\u003c\/li\u003e\n\u003cli\u003eMeets MIL-DTL-23053\/5C and UL 224 VW-1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose heat shrink sleeve for use on wire gauges and terminals that fall within a 0.125 inches pre-shrink inner diameter range, typical in low-voltage control wiring, electrical splices, and connector terminations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, HVAC technicians, or other trades working with wiring and terminal connections. De-energize all circuits before applying heat shrink sleeving to any wire or terminal. Use a heat gun set to an appropriate temperature to evenly activate the sleeve; avoid open-flame torches on polyolefin tubing. Work practices should conform to applicable NEC requirements for insulation and wire protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyolefin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 2:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Before Shrinking\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter After Shrinking\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Thickness After Shrinking\u003c\/strong\u003e: 0.020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrink Temperature\u003c\/strong\u003e: 248 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -67 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 275 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Corrosion-Resistant, Fluid-Resistant, Fungus-Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: MIL-DTL-23053\/5C, UL 224 VW-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51720287879474,"sku":"28104","price":38.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1466f4e7f2bef8b4bbe7cdaf5e1db31.jpg?v=1788562212","url":"https:\/\/voomisupply.com\/products\/import-28104-heat-shrink-sleeve-8-ft-polyolefin-2-1-black","provider":"Voomi Supply","version":"1.0","type":"link"}
