Built from polyolefin with a 2.5:1 shrink ratio, this tubing features a co-extruded construction with a selectively cross-linked outer wall and a meltable inner wall that flows during recovery to create a moisture-resistant seal around conductors and connections. Each stick measures 48 inches in length and ships in a standard case quantity of 125 pieces. Licensed electricians and low-voltage installers use this tubing to terminate, bundle, and protect wire splices, connector backshells, and cable entries in electrical panels, control wiring, and field-assembled harnesses.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for residential and commercial electrical work where a dual-wall construction is needed to provide both mechanical protection and an adhesive-type inner seal. The red color aids in circuit identification or phase coding during installation. Standard applications include protecting wire splices, cable ends, and connector terminations exposed to moisture, vibration, or abrasion in electrical and light industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5:1 shrink ratio for reliable recovery over a range of conductor and connector diameters\u003c\/li\u003e\n  \u003cli\u003eMultiple-wall construction with meltable inner wall that flows and seals during heat application\u003c\/li\u003e\n  \u003cli\u003eSemi-rigid polyolefin outer wall resists abrasion and provides mechanical protection after recovery\u003c\/li\u003e\n  \u003cli\u003e48-inch stick length allows field cutting to exact required lengths\u003c\/li\u003e\n  \u003cli\u003eRed color for circuit or phase identification in multi-circuit wiring systems\u003c\/li\u003e\n  \u003cli\u003eCase quantity of 125 pieces supports production or high-volume field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style dual-wall heat shrink solution for use on standard wire and cable terminations where a 3\/8-inch recovered inner diameter and adhesive-style inner wall seal are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified wiring technicians following applicable NEC guidelines. De-energize and lock out all circuits before applying tubing to any conductor or termination. Apply uniform heat using a calibrated heat gun, working from the center outward to prevent air entrapment and ensure even inner-wall flow. Do not use an open flame as a heat source, as uneven heat can cause charring or incomplete recovery.\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: Polyolefin (co-extruded, selectively cross-linked)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength per Stick\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Quantity\u003c\/strong\u003e: 125 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 10051128599164\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: 7010400848\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51348001128754,"sku":"7010400848","price":936.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530742.jpg?v=1782117576","url":"https:\/\/voomisupply.com\/products\/3m-7010400848-heat-shrink-tubing-3-8-in-48-in-red","provider":"Voomi Supply","version":"1.0","type":"link"}
