Built from cross-linked polyolefin, this sleeve delivers strong resistance to abrasion, corrosion, and chemical exposure. It ships as a 25 ft reel in an uncoated configuration, making it suitable for field-cut applications across a range of conductor sizes from 1\/4 AWG through 4\/0 AWG. The sleeve shrinks quickly with applied heat, reducing installation time and minimizing the need for extensive technician training. Electrical professionals and industrial maintenance crews rely on this product for reliable, long-term cable jacketing in both new installations and retrofit work.\u003c\/p\u003e\u003cp\u003eThis sleeve is designed for applications where cables require durable re-jacketing or phase identification insulation, including bus bar insulation and phase rejacketing in electrical panels, switchgear, and distribution equipment. The medium-wall construction provides greater flexibility compared to heavy-wall alternatives, making it easier to work with in tight spaces or complex cable routing situations. It accommodates conductors ranging from 1\/4 AWG to 4\/0 AWG, covering a broad range of residential and commercial electrical service applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCross-linked polyolefin construction provides split resistance and long-term durability\u003c\/li\u003e\n\u003cli\u003eMedium-wall profile offers greater flexibility than heavy-wall sleeve variants\u003c\/li\u003e\n\u003cli\u003eFast-shrinking material reduces installation time with minimal training required\u003c\/li\u003e\n\u003cli\u003eUncoated 25 ft reel format allows field cutting to required lengths\u003c\/li\u003e\n\u003cli\u003eResistant to abrasion, corrosion, and a wide range of chemicals\u003c\/li\u003e\n\u003cli\u003eSuitable for bus bar insulation and phase rejacketing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with conductors ranging from 1\/4 AWG to 4\/0 AWG.

De-energize and lock out all circuits before applying the sleeve to any conductor or bus bar. Apply even heat using an appropriate heat gun, working progressively along the sleeve to achieve uniform shrinkage. Avoid direct flame sources, which can damage the sleeve material or create uneven shrink.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Range\u003c\/strong\u003e: 1\/4 AWG to 4\/0 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cross-linked polyolefin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReel Length\u003c\/strong\u003e: 25 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Medium-wall, uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051135034842\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7000031509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346759024946,"sku":"7000031509","price":13577.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531842.jpg?v=1782089482","url":"https:\/\/voomisupply.com\/products\/3m-7000031509-heat-shrink-medium-wall-cable-sleeve-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
