Used it to fix my favourite mug handle and also my sunglasses which the handle was snapped and glue won’t hold.Lots of sizes to choose from and shrinks perfectly to secure anything it grips.Wish I’d discovered these sooner they’re so handy and work so well to repair things glue will not hold.Not used on wires and cables but it’ll be perfect for those annoying iPhone cables that keep breaking right at the base.
Very good customer

I repaired a cracked EVAP hose on my 2001 Camry by sliding one of these tubes over it and heating it. For double strength (probably overkill) I then slid a second tube over the first and heated it also. The glue oozed at the edge as expected. Perfect seal and stronger than the original. In addition I first rejuvenated the hose by letting it sit in simmering hot water with wintergreen oil (methyl salicylate). I put 8 drops of wintergreen for 250 cc of water, for one hour. The results are amazing. Saved me from having to find a perfectly molded shaped hose (near impossible for a 24 yr-old car and at what cost) or having to mold a standard straight stock hose. Note I would not try it for a high pressure hose but for low pressure EVAP hoses it is great. Check engine light now off!

Queste fascette termorestringenti sono veramente OTTIME. Valgono ogni centesimo. Robuste, ottimo assortimento, si restringono veramente sino a 4 volte. Prodotto davvero di qualità.L'unico appunto che potrei avanzare riguarda la scatola di plastica in cui sono contenute: Le cerniere posteriori non tengono e la scatola tende ad aprirsi. Un elastico ed il problema è risolto.Soddisfattissimo.

These have worked out great for me. I was rewiring heavy gauge cable for a new bow mount trolling motor, and despite some neg reviews I decided to purchase anyway. I'm not disappointed, these worked out great. they shrunk down tight and with the internal adhesive they created a very watertight seal on all connections. I would recommend these to friends as well as purchase them again in the future.

I ordered this product after research and reviews. Was not disappointed it’s really great stuff I’m a newbie in doing van electrics and solar install and wanted the wiring to be safely protected some may think it’s overboard but I wanted good coverage and sealing. This 4:1 heat shrink was so easy to use I did procrastinate on what size trying to work that out initially but once I got going it was fine I used a heat gun and then welding gloves to protect my hands. Anyway the result was just what I was hoping for and has given my cables of various thickness a really good wrap. Swift delivery and would have no hesitation in re ordering from this seller, many thanks.

Shrinks evenly and seal tight. Easy to work with. Basically it does what’s it claims to do. What more can you ask.

I use shrink tubing for a lot of projects. I have purchased several different brands but this one beats them all, even the more expensive ones that I have used. One of the projects I use it for is to strengthen the connecting ends of all my family’s phone and computer device cables, which seem to fail often from incorrectly pulling them out of the devices. This is the only brand I have found that has a size diameter that can slip over the wider connection and still shrink down to the skinnier wire attached to it. Since I have been using this product, I have not had to buy any more cables for my devices.

I recently purchased the Wirefy 3:1 Heat Shrink with absolutely fantastic results, I loved the shrinking ability, internal permanent waterproof adhesive once it cools after being heated, and the dual layer design for worry free protection and durability.. The 3:1 was amazing, but this 4:1 is unbelievable providing an even greater shrinking ability.. As long as it's from Wirefy, you can't go wrong with either.. I've tried cheaper brands that shrink too much to the point they split themselves open or draw up too much exposing bare wire or the terminal connectors.. These issues are a non-factor with Wirefy Heat Shrink 3:1 and advanced 4:1 Ratio.. Thank you for supporting America and it's Armed Forces!!
