Built from co-extruded polyolefin with a 2.5:1 shrink ratio, it features an integral meltable inner wall that flows into voids and bonds to irregular surfaces during heat application, creating a watertight seal. Each stick measures 48 inches in length and is suitable for use over 3\/8-inch diameter applications. Electrical contractors, HVAC technicians, and marine or industrial electricians install this tubing where a single-wall product does not provide adequate environmental or mechanical protection.\u003c\/p\u003e\n\u003cp\u003eThis tubing is used in residential and commercial wiring applications where splices, terminations, and connectors require strain relief and sealed protection against moisture, chemicals, or corrosion. The semi-rigid construction maintains shape after shrinkage, making it well suited for exposed or bundled conductor runs in control panels, junction boxes, and service entry points. The black color aids in UV identification on exposed runs. It comes supplied in 48-inch sticks with a minimum order quantity of 125 pieces per case.\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 polyolefin construction with selectively cross-linked semi-rigid outer wall\u003c\/li\u003e\n  \u003cli\u003eIntegral meltable inner wall flows into voids for a watertight, bonded seal\u003c\/li\u003e\n  \u003cli\u003e48-inch stick length allows field cutting to required lengths\u003c\/li\u003e\n  \u003cli\u003eBlack color for UV identification on exposed installations\u003c\/li\u003e\n  \u003cli\u003eSuitable for wire splices, terminations, and connector protection in demanding environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style multiple-wall heat shrink solution for use over wire, cable, and connector assemblies requiring a 3\/8-inch nominal tubing size in electrical, HVAC control wiring, and industrial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians and HVAC technicians following applicable NEC requirements. De-energize all circuits before applying heat shrink over conductors or terminations. Use a calibrated heat gun set to the appropriate temperature range for polyolefin tubing, applying heat evenly from the center outward to prevent air entrapment. Avoid open flame as a heat source, as it can scorch or unevenly shrink the tubing and compromise the inner wall seal.\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\u003eNominal Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStick Length\u003c\/strong\u003e: 48 inches\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Quantity\u003c\/strong\u003e: 125 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051128598245\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: 7100034432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344428499250,"sku":"7100034432","price":866.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530728.jpg?v=1782035769","url":"https:\/\/voomisupply.com\/products\/3m-7100034432-heat-shrink-tubing-3-8-in-48-in-black","provider":"Voomi Supply","version":"1.0","type":"link"}
