With a 3:1 shrink ratio, it transitions from 1.1 inches inner diameter before shrinking down to 0.37 inches after activation, providing a tight mechanical and environmental seal over the conductor. Activation begins at 248 degrees F. The red color aids in circuit identification or phase coding on the job site. This sleeve is rated for continuous operation up to 194 degrees F and carries both UL Listed and CSA Certified designations, making it suitable for use in code-compliant installations.\u003c\/p\u003e\u003cp\u003eThis sleeve fits wire sizes from 1 AWG through 3\/0 AWG, covering a broad range of medium-to-large conductor applications including service entrance work, panel feeders, and large branch circuit terminations. The 9-inch overall length provides ample coverage for butt splices, ring terminal lugs, and cable end protection on both copper and aluminum conductors. Electrical contractors and apprentices working on commercial, industrial, and residential distribution wiring will find this sleeve appropriate for high-demand termination points where insulation integrity is critical. Packages ship in quantities of 10 sleeves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3:1 shrink ratio delivers a secure, low-profile fit over large conductors\u003c\/li\u003e\n\u003cli\u003ePolyolefin construction provides abrasion resistance, acid resistance, and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRated for continuous use up to 194 degrees F\u003c\/li\u003e\n\u003cli\u003eActivates at 248 degrees F with a standard heat gun\u003c\/li\u003e\n\u003cli\u003eRed color supports circuit identification in multi-phase or multi-circuit installations\u003c\/li\u003e\n\u003cli\u003eUL Listed and CSA Certified for use in regulated electrical installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with wire sizes from 1 AWG through 3\/0 AWG.

Slide the sleeve over the conductor or termination before making the final connection, then apply even heat from a calibrated heat gun starting at the center and working outward to prevent air pockets. Do not use an open flame, as uneven or excessive heat can damage the sleeve material or underlying insulation. Work performed on service entrance conductors or feeders should comply with applicable NEC requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyolefin\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: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Compatible Wire Size\u003c\/strong\u003e: 1 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Compatible Wire Size\u003c\/strong\u003e: 3\/0 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\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: UL Listed, CSA Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HS4-30LR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51540668842290,"sku":"HS4-30LR","price":246.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/629b7e021738b02ca6ee59a5cd18728b.jpg?v=1785861407","url":"https:\/\/voomisupply.com\/products\/thomas-betts-hs4-30lr-heat-shrink-sleeve-3-1-red","provider":"Voomi Supply","version":"1.0","type":"link"}
