As the sleeve shrinks the adhesive softens and flows into the gaps around the wire and the terminal, then sets as it cools, so the joint comes out sealed rather than just covered. That is the difference that matters on anything exposed to weather, washdown or salt - a plain sleeve keeps splash off but water still travels along the wire underneath it, while a sealed joint does not. The 3:1 ratio also pulls down further than standard tubing, so each size copes with a bigger step between the wire and the terminal body.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBox contents (225 pieces total)\u003c\/strong\u003e\u003cbr\u003e60 x 3mm, shrinks to 1mm\u003cbr\u003e74 x 4.8mm, shrinks to 1.6mm\u003cbr\u003e45 x 6mm, shrinks to 2mm\u003cbr\u003e25 x 9mm, shrinks to 3mm\u003cbr\u003e15 x 12mm, shrinks to 4mm\u003cbr\u003e6 x 18mm, shrinks to 6mm\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003cbr\u003eBlack adhesive lined dual wall heatshrink tubing, 3:1 shrink ratio, 40mm pre-cut lengths\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eApproval\u003c\/strong\u003e\u003cbr\u003eUL 224 VW-1 flame retardant\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePlease note\u003c\/strong\u003e\u003cbr\u003eEvery piece is a 40mm length, sized for terminals and joints rather than for sleeving a run. Adhesive lined tubing needs more heat than plain tubing - keep the gun on it until a small bead of adhesive appears at each end, which is how you know the glue has flowed and the joint is sealed. Stopping as soon as the sleeve looks tight is the usual reason a dual wall joint leaks.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSuitable for\u003c\/strong\u003e\u003cbr\u003eSealing crimp terminals and soldered joints against water, marine and boat wiring, agricultural and plant electrics, trailer, towing and caravan wiring, exterior lighting and sensor repairs, chassis and underbonnet looms\u003c\/p\u003e\n\n\u003cp\u003eAlso known as adhesive lined heatshrink, dual wall heatshrink, glue lined heat shrink, waterproof heat shrink, 3:1 heatshrink, or a marine grade heat shrink assortment box.\u003c\/p\u003e","brand":"DH \u0026 JS Trading Ltd","offers":[{"title":"Default Title","offer_id":56489144418682,"sku":"AT130","price":15.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/2239\/6850\/files\/AT130.png?v=1768621476","url":"https:\/\/www.dhjstrading.com\/products\/225pc-assorted-box-of-adhesive-lined-heat-shrink-tubing-3-1-3mm-18mm","provider":"DH \u0026 JS Trading Ltd","version":"1.0","type":"link"}
