Heat shrink tubing at a 4:1 ratio provides significantly more wall buildup and recovery than standard 2:1 products, making it well suited for irregular or stepped surfaces, connector backshells, and bundled conductor assemblies. Electricians and instrumentation technicians use this type of tubing to provide insulation, environmental sealing, and strain relief on wire harnesses, splices, and terminations across industrial, commercial, and residential electrical systems.\u003c\/p\u003e\u003cp\u003eThis tubing is appropriate for applications where a high shrink ratio is required to conform tightly over connectors, transitions between conductor sizes, or multi-conductor bundles. The 0.945 inch recovered diameter accommodates a range of medium-to-large wire and connector assemblies. It is packaged and sold as an individual unit and is a common stocked item in electrical panel shops, field service kits, and maintenance departments where harness repair and wire management work is performed regularly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4:1 shrink ratio provides high wall thickness recovery for irregular or stepped surfaces\u003c\/li\u003e\n\u003cli\u003e0.945 inch supplied inner diameter accommodates medium-to-large wire and connector assemblies\u003c\/li\u003e\n\u003cli\u003eDual-wall or thick-wall construction typical of 4:1 products offers added mechanical and environmental protection\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for flexible purchasing on repair and maintenance jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use heat shrink sleeve for electrical wire and cable assemblies requiring a 4:1 shrink ratio and a 0.945 inch starting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHeat shrink tubing should be installed by a qualified electrician or instrumentation technician following applicable NEC guidelines. De-energize and lock out all circuits before applying tubing to splices or terminations. Use a calibrated heat gun to apply uniform heat — avoid open flame, which can cause uneven shrinkage or damage the tubing. Ensure the tubing extends sufficiently past each end of the connection to provide full coverage and strain relief.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 4:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied Inner Diameter\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PANDUIT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HSTT4A94-48-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PANDUIT","offers":[{"title":"Default Title","offer_id":51559830520114,"sku":"HSTT4A94-48-5","price":86.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9724d46aa953bac904618da84e4c4b17_f6f3a8ab-807a-4445-a601-410f3a36b295.jpg?v=1786442204","url":"https:\/\/voomisupply.com\/products\/panduit-hstt4a94-48-5-heat-shrink-tubing-4-1","provider":"Voomi Supply","version":"1.0","type":"link"}
