Vintage Double Hose

I was wondering if anyone had any tricks on removing the ring from a DAAM... I have the wrench, but the corrosion has it frozen solid... I'm afraid if I try anymore torque I'll strip the grooves on the ring.

Have you tried some vinegar in an ultrasonic cleaner?

Spray the piece with Corrosion Block and let sit for a while. Heat the backside with a torch or heat gun but not too hot, about 200F. If it won't move under moderate force, let cool and try again to remove the ring with a pin spanner or wrench designed for this purpose. Normally, I would wait until cool but it is possible that the ring was set with thread lock. In any case, heat will draw the penetrating oil into the ring and should free the thing up.

I soaked it in an ultrasonic last night... if that doesn't work I'll go with the heat... Thanks

heat can be the enemy of such thin metal. The cans could end up with a warp in them. bryan has a regulator cleaner which I have found helps to loosten the rimngs quite well. This regulator cleaner disolves salt deposits , and leaves a non oily dry film on the parts which is anti corrosive. Before putting heat to it, I would put the part in the freezer overhight , then drop it into some boiling hot water to see if the expanding and contracting would help loosen things up. Kinda like when you have to change a tie rod end on a car.

I have never had to pound on a ring using the above

It would take a lot of heat to warp brass permanently. I have soldered aluminum which is only 0.035 thick-- 700F and no problems. One thing, if the chrome regulator part is heated to high temps, the chrome will blacken and not come back. A propane torch is not hot enough to do this. Stay away from MAPP gas.
