Slide the sleeve over the two conductors, warm it with a hot air gun, and the solder ring inside melts into the strands while the sleeve shrinks down and seals the joint at both ends. No crimpers, no soldering iron, no separate heat shrink to slide on afterwards - which is the point when the joint is halfway up a wheel arch or behind a dashboard where you can get a heat gun in but not two hands and a pair of crimpers. The solder makes it a proper electrical joint rather than a mechanical grip, so it will not work loose under vibration, and the sealed ends keep damp out of the copper.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBox contents (100 pieces total)\u003c\/strong\u003e\u003cbr\u003e25 x white, 0.2 - 0.5mm²\u003cbr\u003e25 x red, 0.5 - 1.5mm²\u003cbr\u003e25 x blue, 1.5 - 2.5mm²\u003cbr\u003e25 x yellow, 3.0 - 6.0mm²\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eColour code\u003c\/strong\u003e\u003cbr\u003eWhite 0.2-0.5mm², red 0.5-1.5mm², blue 1.5-2.5mm², yellow 3.0-6.0mm² - the same code as standard crimp terminals\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note\u003c\/strong\u003e\u003cbr\u003eThese need a proper hot air gun, not a hairdryer. The solder ring has to reach melting point and flow into the strands, so keep the heat on until you can see the solder has run and gone shiny right through the joint. A sleeve that has shrunk but whose solder has not flowed looks finished and is not - it is the commonest way these get fitted wrongly. Twist or lay the conductors together inside the sleeve before heating, and let the joint cool undisturbed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for\u003c\/strong\u003e\u003cbr\u003eLoom and harness repairs, lighting and sensor wiring, trailer and towbar work, marine and caravan electrics, motorcycle and quad wiring, awkward access repairs, any joint that has to survive damp and vibration\u003c\/p\u003e\n\u003cp\u003eAlso known as solder sleeves, solder seal connectors, solder seal butt connectors, heat shrink solder connectors, waterproof solder connectors, or a solder sleeve assortment box.\u003c\/p\u003e","brand":"DH \u0026 JS Trading Ltd","offers":[{"title":"Default Title","offer_id":56479795216762,"sku":"AT149","price":41.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/2239\/6850\/files\/AT149.webp?v=1769522551"},{"product_id":"225pc-assorted-box-of-adhesive-lined-heat-shrink-tubing-3-1-3mm-18mm","title":"225pc Assorted Adhesive Lined Heat Shrink Tubing Box - Black 3:1, 3mm to 18mm","description":"\u003cp\u003e\u003cstrong\u003e225pc Assorted Box of Adhesive Lined Heat Shrink Tubing\u003c\/strong\u003e - 225 black 3:1 dual wall heatshrink sleeves in six diameters from 3mm to 18mm, supplied as 40mm pre-cut pieces.\u003c\/p\u003e\n\n\u003cp\u003eAdhesive lined tubing has a layer of hot melt glue on the inside. 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.
