Built from co-extruded, selectively cross-linked polyolefin, it features a 2.5:1 shrink ratio and an integral meltable inner wall that flows on heat application to form a moisture-resistant seal around the substrate. Each piece ships as a 48-inch stick and weighs 0.2 pounds. Licensed electricians and electrical contractors install this tubing on cable bundles, connector backshells, and terminal splices where a rigid, sealed sleeve is required.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for residential and commercial electrical work as well as industrial wiring applications where a durable, semi-rigid protective sleeve is needed over conductors, terminals, or connectors. The meltable inner wall is particularly valuable in outdoor, wet, or vibration-prone installations where moisture ingress at wire terminations is a concern. Each 48-inch stick can be cut to length on the bench before installation, making it practical for a wide range of termination sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5:1 shrink ratio accommodates a range of conductor and connector diameters\u003c\/li\u003e\n  \u003cli\u003eCo-extruded multiple-wall construction with integral meltable inner wall for sealed terminations\u003c\/li\u003e\n  \u003cli\u003eSemi-rigid polyolefin outer wall provides mechanical protection after recovery\u003c\/li\u003e\n  \u003cli\u003e0.75-inch supplied diameter available in 48-inch sticks for bench cutting to length\u003c\/li\u003e\n  \u003cli\u003eBlack color for UV resistance and standard electrical identification\u003c\/li\u003e\n  \u003cli\u003eSelectively cross-linked construction maintains dimensional stability during heat application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-format multiple-wall heat shrink sleeve for electrical wire terminations, splices, and connector backshells where a semi-rigid, sealed installation is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians following applicable NEC guidelines. De-energize all circuits completely before applying heat shrink tubing to any conductor or termination. Use a calibrated heat gun set to the appropriate recovery temperature and apply heat evenly along the length of the tubing to ensure full shrinkage and uniform inner-wall melt flow. Do not use an open flame, as uneven heat will cause incomplete recovery or damage to the tubing.\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 Type\u003c\/strong\u003e: Multiple-wall, semi-rigid with meltable inner wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cross-linked polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupplied Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength per Piece\u003c\/strong\u003e: 48 inches\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: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 45\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: 7010350189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345757438258,"sku":"7010350189","price":721.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530734.jpg?v=1782062325","url":"https:\/\/voomisupply.com\/products\/3m-7010350189-heat-shrink-tubing-0-75-in-semi-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
