True to size, high quality, durable heat shrink tubing
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.

The cost
Most important the cost we were paying five dollars a foot we got this material for about $.41 a foot it works just as good only difference is it might take 5 to 10 seconds longer to shrink

Best I've found
Just got this shrink tube yesterday. used about 2' of it today. Very pleased. Shrunk it onto a #22 conductor, couldn't pull it off. Meaty stuff, too.

Muy bueno
Cumple perfectamente con la descripción. Funda de calidad que reduce 3:1 y con el pegamento sellador como prometido. Lo uso para aislar unos componentes electrónicos soldados con estaño y va perfecto. Buena compra.

End result looks factory
Shrinks very well. The protective substance on the inside works very well to keep out any moisture. My only gripe is that it has a lot of bends which makes it difficult to push the wires through. It requires something like piano wire to pull the wires through with less issues.

Gain thermo efficace et reellement etanche! Epaisse, difficile a retirer une fois chauffer, rien a voir avec les gaines plus accessibles
