Starting at 1 inch inside diameter before shrinking, this sleeve recovers to 0.32 inches ID at a 3:1 shrink ratio, providing a tight, secure fit over conductors ranging from 4 AWG to 4\/0 AWG. At 6 inches in overall length, the sleeve delivers substantial coverage per section. Licensed electricians and electrical contractors are the primary installers, though it also sees use in marine, industrial, and HVAC control wiring environments where moisture, corrosion, and fluid exposure are concerns.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is suited for residential and commercial electrical work where reliable insulation and environmental protection are required at wire ends, lugs, and butt splices. Its rated operating range of -67 degrees F to 230 degrees F makes it appropriate for both indoor and outdoor installations including conduit entry points, panel terminations, and service entrance connections where conductors in the 4 AWG to 4\/0 AWG range are common. The red color aids in circuit identification during installation and service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3:1 shrink ratio recovers from 1 inch ID to 0.32 inches ID for a firm, conforming fit\u003c\/li\u003e\n  \u003cli\u003ePolyolefin construction provides corrosion resistance, fluid resistance, fungus resistance, and water resistance\u003c\/li\u003e\n  \u003cli\u003eCompatible with wire sizes from 4 AWG to 4\/0 AWG\u003c\/li\u003e\n  \u003cli\u003eActivation temperature of 249.80 degrees F allows controlled application with a heat gun\u003c\/li\u003e\n  \u003cli\u003eWide operating range from -67 degrees F to 230 degrees F suits harsh-environment installations\u003c\/li\u003e\n  \u003cli\u003eWall thickness after shrinking of 0.10 inches provides durable mechanical and dielectric protection\u003c\/li\u003e\n  \u003cli\u003eCSA Recognized and UL Recognized with RoHS compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard heat shrink sleeve for copper and aluminum conductors from 4 AWG to 4\/0 AWG.

De-energize and lock out all circuits before applying heat shrink sleeves to any conductors or terminations. Apply heat evenly using a calibrated heat gun, working from the center of the sleeve outward to prevent air pockets and ensure uniform recovery. Avoid open-flame tools, which can scorch the material or cause uneven shrinkage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Before Shrinking\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter After Shrinking\u003c\/strong\u003e: 0.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness After Shrinking\u003c\/strong\u003e: 0.10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Temperature\u003c\/strong\u003e: 249.80 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: 230 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Wire Size\u003c\/strong\u003e: 4 AWG to 4\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Recognized (File E157227), CSA Recognized (File LR38227), RoHS Compliant\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010398980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51696752492850,"sku":"7010398980","price":117.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b75c1725add90779d15e05c6a9ee3d7_8c374d37-5bb0-42f7-9dd0-645b5bb10d98.jpg?v=1788345855","url":"https:\/\/voomisupply.com\/products\/3m-7010398980-heat-shrink-sleeve-1-in-3-1-polyolefin-red","provider":"Voomi Supply","version":"1.0","type":"link"}
