Are we finally going to get away from soldering and  all the problems that are associated with it? According to this post at Technician Brian.com - Sub Zero is demonstrating Lokring fittings. We’ve seen a couple of compression fittings on the Whirlpool fridges but no information has been presented on how to make the connection in the field. I would love to be able to use this, especially for a process stub to check pressures, etc.

As an aside, when guys find leaks on the Whirlpool compression fittings, they’ve been cutting them out and joining the ends together with a sleeve. Twice, I have simply heated the compression and soldered completely over it and not had any problems. It looks kind of ugly, but it works for me.

Whirlpool, KitchenAid and Inglis dryers all have this style of idler pulley. This one was squeeling and was quite worn. I did a close up of the wheel shaft where you can see it has worn the hole oblong.
