Wirefy Heat Shrink Tubing Kit - 3:1 Ratio - Adhesive Lined - Waterproof Marine Grade Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - White - 275 PCS

I'm now on my 2nd box of these heat shrink tubes. I find them very good quality, they have a good shrink ratio, and the adhesive creates a good water proof seal. Used for amateur radio antennas and electronic repairs / projects.

a must to have on hand in the shop.Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using.Lots of different colours and size choice and inexpensive.Seal onto wire with a low flame on the blow lamp. But heat gun equally as good.

Most heat shrink tubing is coloured (usually black) so you cannot see what you have put the tubing over. There are times when you need to see what the tubing has been placed over. I intended to use some to put over some USB sticks to make the identifying label more permanent. Unfortunately I underestimated the size of the USB stick so only the largest ones would fit. Worked well in this application. The others will be added to the general use pile.

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.

Very good quality, price and delivery.

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.

Bought these to put on ends of speaker cable and repair an iPhone cable that was fraying at connector. Chord speaker cable had been shrink wrapped by so called professional (yellow wrap in picture 2)Did last a few years but I was never happy with it. It eventually became loose from cable so I gave these a go. Wish I’d done it myself rather than pay someone to do an inferior job. So easy to do and the finish is, well, better than what I got from a high end music store in Edinburgh. The shrink ratio is a big factor if you need to fix something like a phone cable as it needs to slip over the connector. 3:1 ratio is good for that. Would never have worked with the cheaper 2:1. And the glue on the inside is extra strength on the finish.

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.

Amazing heat shrink. 3:1 with adhesive for complete sealing. I wish they sold single sizes instead of multi-packs though because I'm out of the larger sizes.

Loved these things, great to ensure all cables are protected

Arrived as *white* and not *clear* walls as advertised, otherwise glue is clear and worked as expected.

LA CANTIDAD DE RESINA ES LA ADECUADA ADEMAS DE LA CONTRACCION ES EXCELENTE PARA SELLAR CABLES QUE VAN CERCA DEL MOTOR

Sono di spessore consistente e hanno un elevato restringimento... Le consiglio ... è la seconda volta che le prendo.
