Starting at 1.1 inches inner diameter before shrinking, it recovers down to 3\/8 inches, conforming tightly to the underlying wire or connector. At 5 inches in overall length, it covers a practical service span for field splices and end terminations. The sleeve activates at 248 degrees F and holds a maximum operating temperature of 194 degrees F. Electricians and low-voltage technicians install this product wherever a clean, code-compliant insulation sleeve is needed on conductors ranging from AWG 1 through AWG 3\/0.\u003c\/p\u003e\n\u003cp\u003eThe HS4-30 is suited for residential and commercial electrical work, including service entrance conductors, panel feeder terminations, motor lead connections, and utility splice protection. The 3:1 shrink ratio makes it a reliable choice when installers need tight recovery over irregular or stepped surfaces such as crimped lugs and butt splices. The black polyolefin construction provides resistance to abrasion, acid exposure, and corrosion, making it appropriate for conduit runs, wet locations, and industrial environments where conductors face mechanical or chemical stress. Each package contains 20 sleeves.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3:1 shrink ratio recovers from 1.1 inches ID to 3\/8 inches ID for tight conformance over lugs and splices\u003c\/li\u003e\n  \u003cli\u003ePolyolefin construction rated for abrasion, acid, and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCompatible with AWG 1 through AWG 3\/0 wire sizes\u003c\/li\u003e\n  \u003cli\u003eActivates at 248 degrees F with a maximum continuous operating temperature of 194 degrees F\u003c\/li\u003e\n  \u003cli\u003eCSA Certified and UL Listed for code-compliant installations\u003c\/li\u003e\n  \u003cli\u003e5 inches overall length provides adequate coverage for field terminations and splices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heat shrink sleeve for electrical conductors in the AWG 1 through AWG 3\/0 range, compatible with standard crimped terminals, butt splices, and ring lugs commonly used in residential, commercial, and light industrial wiring applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians following applicable NEC requirements. Power down and lock out the circuit before applying any tubing to a conductor or termination. Apply heat evenly using a heat gun, working from the center outward toward the ends to prevent air pockets and ensure uniform recovery. Do not use an open flame to shrink the tubing, as uncontrolled heat can damage the sleeve or adjacent insulation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 3:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Before Shrinking\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter After Shrinking\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Compatible Wire Size\u003c\/strong\u003e: AWG 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Compatible Wire Size\u003c\/strong\u003e: AWG 3\/0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Temperature\u003c\/strong\u003e: 248 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 194 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Abrasion-Resistant, Acid-Resistant, Corrosion-Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA Certified, UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20 sleeves\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\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: THOMAS BETTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HS4-30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51539035652402,"sku":"HS4-30","price":453.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2cbf8e542c85912a87c3530cf014efc.jpg?v=1785833382","url":"https:\/\/voomisupply.com\/products\/thomas-betts-hs4-30-heat-shrink-sleeve-3-1-1-1in-id-black","provider":"Voomi Supply","version":"1.0","type":"link"}
