Built from polyolefin, it uses a 2.5:1 shrink ratio and a co-extruded construction with selective cross-linking to produce an integral, meltable inner wall. When heated, the inner wall flows and bonds around conductors, connectors, or splices, creating a mechanically secure and moisture-resistant seal. Each stick measures 48 inches in length. Licensed electricians and wire harness technicians are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis tubing is suited for use in electrical enclosures, control panels, marine wiring, automotive harnesses, and industrial equipment where a robust, sealed sleeve is required over conductors, splices, or connector backshells. The meltable inner wall makes it appropriate for applications where adhesive-style bonding and environmental sealing are necessary. It is supplied in individual 48-inch sticks with a minimum order quantity of 5 pieces per case.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5:1 shrink ratio for coverage over a range of conductor and connector sizes\u003c\/li\u003e\n\u003cli\u003eCo-extruded semi-rigid polyolefin construction with integral meltable inner wall\u003c\/li\u003e\n\u003cli\u003eSelectively cross-linked outer wall provides structural rigidity after recovery\u003c\/li\u003e\n\u003cli\u003eMeltable inner wall flows on activation to seal and bond to substrate\u003c\/li\u003e\n\u003cli\u003e48-inch stick length allows field cutting to required lengths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a multiple-wall heat shrink sleeve for electrical splices, connector backshells, and conductor terminations in residential, commercial, and industrial wiring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed electricians or qualified wire harness technicians. De-energize and lock out all circuits before applying heat shrink sleeving to any conductor or termination. Use a calibrated heat gun capable of reaching the tubing manufacturer recovery temperature, and apply heat evenly along the length of the tubing to ensure uniform shrinkage and full inner-wall flow. Installations in wet or outdoor locations should comply with applicable NEC requirements for insulation and sealing methods.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 with meltable inner wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStick Length\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051128597187\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: 7100089307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344982147378,"sku":"7100089307","price":213.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530636.jpg?v=1782047158","url":"https:\/\/voomisupply.com\/products\/3m-7100089307-heat-shrink-polyolefin-tubing-48-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
