It features a 2.5:1 shrink ratio and a co-extruded construction with a selectively cross-linked outer wall and an integral meltable inner wall. When heated, the inner wall flows to seal around conductors, terminals, and splices, creating an environmental barrier that resists moisture, dust, and contaminants. Each stick measures 48 inches in length with a 0.25 inch diameter. Licensed electricians and electronics technicians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for residential and commercial electrical work where a secure, environmentally sealed termination or splice is required. Common applications include wire harness protection, connector backshell sealing, terminal insulation, and butt splice covering. It is used in control panels, HVAC low-voltage wiring, marine wiring, and industrial equipment where a clean, mechanically stable heat shrink sleeve is needed. The black color provides UV resistance context and easy visual identification in wiring assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5:1 shrink ratio for coverage over a wide range of conductor and terminal sizes\u003c\/li\u003e\n  \u003cli\u003eSemi-rigid polyolefin outer wall provides mechanical protection after recovery\u003c\/li\u003e\n  \u003cli\u003eMeltable inner wall flows on heating to seal around irregular surfaces and terminals\u003c\/li\u003e\n  \u003cli\u003eCo-extruded multiple-wall construction eliminates the need for separate adhesive-lined tubing\u003c\/li\u003e\n  \u003cli\u003e48 inch stick length allows field cutting to required lengths\u003c\/li\u003e\n  \u003cli\u003eBlack color finish for UV-exposure and high-contrast wiring identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use heat shrink sleeve for electrical wiring, terminal connections, and splice insulation in residential, commercial, and industrial installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified technicians. De-energize all circuits before applying heat shrink tubing to any wiring or terminal. Use a calibrated heat gun rather than an open flame to apply uniform heat and ensure consistent recovery without scorching. Follow applicable NEC guidelines for wire insulation ratings and conductor protection in the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 2.5:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Construction\u003c\/strong\u003e: Multiple-wall, co-extruded semi-rigid polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Wall Type\u003c\/strong\u003e: Meltable adhesive inner wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches per stick\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 7100089306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342728102194,"sku":"7100089306","price":1437.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530729.jpg?v=1782004858","url":"https:\/\/voomisupply.com\/products\/3m-7100089306-heat-shrink-tubing-0-25-inch-48-inches-black","provider":"Voomi Supply","version":"1.0","type":"link"}
