4:1 Shrink tubing
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.

These seem good quality. I wish there were a few more of the smaller ones
These seem good quality. I wish there were a few more of the smaller ones. the product does really grip the wire and glue comes out when tight so i am sure will create a good seal

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.

La meilleure gaine thermorétractable que j'ai utilisé dans ma vie jusqu'à présent. Facile à appliquer, très solide et la colle la fixe bien sur place. Le ration de rétrécissement de 4:1 est bien respecté. Le prix est très raisonnable en plus.

This stuff works great.Not just for wiring,I’ve used it to insulate tool handles, patch cracked or chafed or otherwise damaged outer sheathing of brake or clutch cables on bikes etc.I’ve ordered several sizes of the rolls and multiple boxes of the pre-cut assorted sizes over the past few years. Comes either 3:1 or 4:1 shrinkage rates . Once you figure out what you use the most it’s great to be able to get 20-25’ rolls . It has adhesive on the interior that really makes a great seal for keeping moisture out.There may be comparable products out there but I am going to continue to use this brand. I think the price is fair and you get what you pay for.
