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

Great tubing
Really good tubing with excellent shrink - 4 to 1 is worth buying. Good adhesion. Joints really strong. Good number of reasonable size sleeves, but could have done with some smaller ones in the set. Overall, well worth buying
