would recommend these
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.

Good shrink rate probably a genuine 3:1 or better.Strong and thick with good glue. Worth he extra
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.

Proper heavy-duty heat shrink — feels way tougher than the cheap stuff
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.

Easy to use
Love these work a treat to finish wiring jobs, just apply a heat gun and they shrink and tighten up , protecting the wiring , these are not slit so need to go onto wires before you connect them

Love this tubing kit
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

Purchased 7 Oct 2025 delivered next day. It is magic
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.

The cables are connected, and the sonar is working. I haven't had a chance to put it in the water yet. If something changes, I will edit the review For now 5 stars EDIT// The cable was submerged in water for about 12 hours and everything still works. Very good quality, I highly recommend it!
