Part of the 3M FP-301 series, this tubing is rated for 600 volts and carries both UL and CSA approvals, making it suitable for electrical insulation, bundling, and strain relief applications in commercial and industrial wiring work. It features a minimum expanded diameter of 0.125 inches, a maximum recovered diameter of 0.062 inches, and a wall thickness of 0.02 inches. Electricians and wire harness technicians reach for FP-301 tubing when they need a lightweight, flexible solution that conforms tightly to conductors and splices after heat is applied.\u003c\/p\u003e\n\u003cp\u003eThis tubing is appropriate for low- and medium-voltage electrical work where a clean, durable insulating sleeve is required. Common applications include wire splicing, connector insulation, cable identification, and environmental protection of terminations in control panels, motor wiring, and equipment harnesses. The 500-foot continuous spool format suits contractors and shop technicians who cut tubing to length on demand for repetitive production or service work. The black color supports heat absorption during shrink and provides a uniform finished appearance on dark-jacketed cable assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible polyolefin construction for conformability over irregular surfaces and bends\u003c\/li\u003e\n  \u003cli\u003eMinimum expanded diameter of 0.125 inches with maximum recovered diameter of 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e600-volt voltage rating suitable for standard electrical insulation tasks\u003c\/li\u003e\n  \u003cli\u003eUL and CSA approved for use in code-compliant electrical installations\u003c\/li\u003e\n  \u003cli\u003e0.02-inch wall thickness provides insulation without adding significant bulk\u003c\/li\u003e\n  \u003cli\u003e500-foot spool format reduces per-foot cost for high-volume or recurring work\u003c\/li\u003e\n  \u003cli\u003eManufactured in the United States\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 1\/8-inch cable size applications requiring UL- and CSA-listed flexible polyolefin sleeving at 600 volts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or trained wire harness technicians following applicable NEC guidelines for insulation and splicing. De-energize all circuits before applying tubing to conductors or terminations. Apply heat evenly using a heat gun set to an appropriate temperature range for polyolefin materials, working from the center outward to prevent air pockets. Do not use an open flame, as uncontrolled heat can damage tubing integrity or adjacent components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Flexible Polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Expanded Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Recovered Diameter\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpool Length\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL, CSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 21.59 inches L x 22.15 inches W x 7.88 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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: FP0.125BK500FT-L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51284012695858,"sku":"FP0.125BK500FT-L","price":1000006.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279296.jpg?v=1781066023","url":"https:\/\/voomisupply.com\/products\/3m-fp0-125bk500ft-l-fp-301-heat-shrink-tubing-500-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
