Insulates crimped joins and spliced wires on automotive, marine and 12V\/24V jobs. Fits a divided storage case so each size stays sorted at the bench.\u003c\/p\u003e\n\u003cp\u003eSingle-wall, non-adhesive polyolefin. Flame-retardant and self-extinguishing, rated to 300V. The 2:1 shrink ratio pulls each tube down to about half its original diameter under heat and grips the joint underneath for an insulated finish. Single-wall means it insulates but does not seal against water, so this kit is for dry-side insulation work; for a water-tight seal around battery lugs or outdoor joints, use adhesive-lined dual-wall tubing instead.\u003c\/p\u003e\n\u003cp\u003eHeat the tube evenly with a proper heat gun, not a naked flame, until it shrinks snugly around the wire. Pick a diameter that slides on easily before shrinking, not one that just fits, otherwise the shrink range cannot do its job.\u003c\/p\u003e","brand":"Elevate Automotive","offers":[{"title":"Default Title","offer_id":39802185416813,"sku":"LV3360","price":69.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/5941\/2333\/files\/dual-wall-heat-shrink-kit-adhesive-lined-3-1-shrink-ratio-300pcs-1.webp?v=1792052035","url":"https:\/\/elevateauto.com.au\/products\/heat-shrink-kit-300pcs-9-sizes-red-black","provider":"Elevate Automotive","version":"1.0","type":"link"}
