Designated as part of the FP-301 series, this tubing shrinks when exposed to heat, creating a snug, protective sleeve around wire splices, terminals, and cable bundles. It is commonly installed by electricians, HVAC technicians, and low-voltage control wiring professionals who need reliable insulation and mechanical protection on conductors and connections. The clear finish allows visual inspection of the underlying wire or component after installation.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for electrical and electronic wiring applications in residential, commercial, and light industrial environments. It works well for insulating terminal connections, wire harnesses, and repair splices in HVAC control circuits, panel wiring, and general electrical service work. The 48-inch length is provided on a small spool format, making it easy to cut to the required length on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible polyolefin construction provides durability and consistent shrink performance\u003c\/li\u003e\n  \u003cli\u003eClear finish allows visual confirmation of the covered connection after shrinking\u003c\/li\u003e\n  \u003cli\u003e48-inch length suits a wide range of field-cut applications\u003c\/li\u003e\n  \u003cli\u003eThin-wall design accommodates tight connector profiles and close-clearance installations\u003c\/li\u003e\n  \u003cli\u003eFP-301 series designation indicates standard dual-wall thin-wall heat shrink specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use heat shrink tubing for electrical insulation and wire protection applications requiring a 1-inch diameter thin-wall polyolefin sleeve.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified HVAC and low-voltage technicians. De-energize all circuits before applying heat shrink tubing to any wiring or terminal connection. Use a heat gun at the appropriate temperature setting and apply heat evenly along the length of the tubing to achieve a uniform shrink. Follow applicable NEC guidelines for wire insulation and termination practices in the jurisdiction where the work is performed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Series\u003c\/strong\u003e: FP-301\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Flexible Polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Clear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Thin-Wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051128596050\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: 7000133521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346767380786,"sku":"7000133521","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530601.jpg?v=1782089724","url":"https:\/\/voomisupply.com\/products\/3m-7000133521-heat-shrink-thin-wall-tubing-fp-301-clear-48-in","provider":"Voomi Supply","version":"1.0","type":"link"}
