Built from co-extruded, selectively cross-linked polyolefin, it features a 2.5:1 shrink ratio and an integral meltable inner wall that flows into voids and around irregularities during heat application, creating a moisture-resistant seal. Each stick measures 48 inches in length. The tubing ships in a black finish and is sold per piece. Licensed electricians, wire harness assemblers, and field service technicians are the primary installers of this product type.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for applications requiring environmental sealing, strain relief, and insulation on wire splices, terminations, and cable bundles. The semi-rigid construction provides added mechanical protection compared to standard single-wall tubing. Common use cases include industrial control panels, marine wiring, automotive harnesses, and utility service equipment where moisture ingress and abrasion resistance are critical requirements. The 48-inch stick length allows techs to cut to the length needed on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5:1 shrink ratio accommodates a range of wire and connector diameters\u003c\/li\u003e\n  \u003cli\u003eDual-wall construction with meltable inner adhesive layer seals against moisture and contaminants\u003c\/li\u003e\n  \u003cli\u003eSemi-rigid polyolefin outer wall provides mechanical protection after recovery\u003c\/li\u003e\n  \u003cli\u003eCo-extruded and selectively cross-linked construction for consistent wall thickness\u003c\/li\u003e\n  \u003cli\u003eBlack finish aids UV identification and blends with standard wiring conventions\u003c\/li\u003e\n  \u003cli\u003e48-inch stick length allows field cutting to required size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade option for standard multiple-wall heat shrink tubing applications on 1\/8-inch nominal diameter wire, cable, and connector terminations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified electricians or wire harness technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to live wiring assemblies. Apply heat evenly using a heat gun moving along the length of the tubing to avoid scorching; do not use an open flame. Allow the tubing and inner adhesive wall to fully recover and cool before restoring power or handling the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Inside Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\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, semi-rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyolefin (co-extruded, selectively cross-linked)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Wall\u003c\/strong\u003e: Meltable adhesive\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\u003eUPC\u003c\/strong\u003e: 00051128598214\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: 7010400807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343971025202,"sku":"7010400807","price":1554.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530654.jpg?v=1782026148","url":"https:\/\/voomisupply.com\/products\/3m-7010400807-heat-shrink-tubing-1-8-in-48-in-black","provider":"Voomi Supply","version":"1.0","type":"link"}
