The press screw on mine started to seize up and gall the threads on the first 2 uses. Found out there is no lubricant on the threads, bad for aluminum. I cleaned it up and put some oil and anti sieze on the threads, and it did my vehicles AC lines perfectly.
On the first crimp the chrome finish on threads flaked off and everything bound up. After a good cleanup it worked perfect. Very nice looking crimps. Good product, it would have better to just used a standard bolt. ( no chrome)
this is a great buy for the price,tooling is fine not the most expensive. super for a home builder, not production. works great, fast to change dies,no info with tool,i got crush info from other tools.but worked perfactly. love it.AAAAAAAAAAA.
It is what it says it is. Apparently these can get quite pricy, but this version of it is very reasonable. It is hefty, sturdy, easy to use, has all of the dies in the case, and worked great on my reduced barrier hoses / fittings.
