Wirefy 3/8" Heat Shrink Tubing - 3:1 Ratio - Adhesive Lined - Marine Grade Heat Shrink - 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.

Good product- does the job

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.

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.

Have use this tubing kit many a time. Has repaired and secured/made safe numerous house hold elecltrical item. Has varied sizes so no worries about cable. Easy to use and connects over the bare wire or covered wires. I use a small chefs blow torch to warm the tubing untill it shrinks to fit as not to hot

Very good quality, price and delivery.

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.
