Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll

Very good value and does exactly what it is supposed to do

These are great. Really pleased. I managed to wrap a 1mm cable with these. The shrink rate is good and they're thick so they should insulate well. The glue also works well. They are expensive but the job looks tidy and they should last me for years.

This brand makes good quality heat shrink. My first choice now.

I had a snapped and bent aluminum boat canopy frame which I had straightened and repaired with tube inserts and rivets. Fine as far as it goes but I had the bright idea of encasing it in heat shrink to prevent any rough spots damaging the canopy, and to disguise the agricultural nature of the repair in general. I tested several different types of heat shrink, and this one is the clear winner. It is nice and thick, looks great, and I was able to shrink 5 metres of it with a blowtorch without scorching it at all. Add to that its excellent substrate of hot glue, and it's even strengthened the poles somewhat by laminating them. I'm absolutely delighted with the result, which would not have been possible with an inferior product.

Good quality but pricey, but if you are protecting electrics, then this is the one. Wish it came in shorter lengths, so I could have gotten a size down too. Shrinkage is uniform, have to cut open to re do and the wire comes away neatly which is also a bonus. Very durable but measured diameter wrong, but that's on me. I've used this on all my bikes wiring and seems solid so far.

I have various solar powered lights outside that don't like the British weather, water gets in to them and the wires decay/rust. Rather than purchase new lamps, I like to re-wire and weather proof connections with these heat shrink sleeves. Also these sleeves have a type of glue inside that melts and seals the connection. Does a really good job. I recommend them!

Grabbed this Wirefy 180-piece kit because I was sick of those thin heat-shrink tubes that feel like they’d tear if you look at them wrong. These ones are the total opposite — thick, solid, and the adhesive lining actually works instead of turning into a weird gummy mess. Once you heat them up they grip the wire like they’re never letting go. I used a bunch on some 12V wiring and a dodgy cable repair on my pressure washer, and they shrank clean and tight with zero gaps. The 3:1 ratio is really noticeable too — you can fit them over connectors, splices, even slightly bulky joins, and they still cinch down properly. Sizes are well mixed, so you’re not stuck with 100 tiny ones and only two useful pieces. The black colour also just looks clean and professional compared to the rainbow packs you sometimes see. Honestly, once you use proper adhesive-lined shrink like this, going back to the cheap stuff feels like torture. If you do any kind of wiring — automotive, hobby electronics, even random household fixes — this kit is absolutely worth having on hand.

Watch out the glue is strong, made a stupid mistake & had to cut the wire, redo all the ends, so now used non adhesive shrink on the connections & then once completed cover with the adhesive shrink. I've used adhesive shrink in ship repair, it is great.

tutto ok, come da descrizione

Good heat shrink tube. Finely packed. Works as it should do.

Viene en buena cantidad y tamaños, se encogen mucho más que otros tubos retractiles que he usado, y el pegamento sella muy bien, me sirvieron mucho.

Très bon produit, conforme.

I really like Wirefy Heat Shrink Tubing. It works well and has been very durable for every application. I've had zero issues with moisture or tear. It is true to size. It leaves very little residue if needing to be removed, but the adhesion is strong enough that there is no slippage once the shrinking is accomplished. Great value too. Flexibility differs depending on the type of wire used, but I find the 3:1 to be sufficiently flexible. I also find that the listed heat shrinkage sizes are true. No issues. Lovely product.
