Google 'Proto 9526', its a screw extractor.

I want to buy it, but I can't find videos of how its used. I've never seen this type of tool before and I want to learn. Little help guys

You tap it into the hole lightly and turn with a wrench

The advantage it has over a Helical extractor like an "easy-out" is it doesn't expand the broken part and wedge it tighter into the hole destroying the threads when you eventually get it out.

I bought that tool to do the exact job you're doing.

Aha thanks man. You're the man

Soak it with PB Blaster for a day or so as well, when you install the new one use some Nickle Antiseize on it's threads.

It's caused by "Galvanic Corrosion" your fitting and the head form a battery when "wet" and bond to each other.

That's great Ian. Thanks

Very welcome!
