I got my from Harbor Freight for like $15. It has lasted for years.

+2 that sucker throws some heat!

In a prototype automotive shop I worked at, a heat gun like the Harbor Freight one was used, but it had a metal C at the end. The cup shape created a nice hot area for the sumitube to shrink onto brake and fuel lines.

Here is an example of the end - which I am sure you can find for much cheaper. https://www.rehabmart.com/product/heat-gun1-5307.html

corded Harbor freight (less than $10 ) at least 10 yrs ago. actually still works after being flooded (AUG 16) with 41 inches for several days. ...drill sgt.

I’m not an expert obviously but seems like heat shrink only needs a temp of about 70C, also sounds like 10-22g wiring insulation starts to melt around 90C (seems like a low bar to me though). These temps are at the low end of any heat gun.

You don't need a huge adjustment range on a heat gun to do electrical heat shrink. I don't think I've ever had a heat gun with more adjustability than high/low (if that). You just put the heat on it long enough to shrink the heat shrink but not long enough to melt anything.

Around $20 at home depot Wagner Heat gun.

I used it to heat shrink the connections for 10 lights on my deck.
