I wouldn't use either one on steam if I had the choice.

This is another case of "just because you can, doesn't necessarily mean you should".

I've used 3" mega press for a few repairs on a main. With this job it was the best option to avoid a major project. You have to specify the right fittings and ensure the pipe is supported correctly. It has its place, just not fond of using it for every fitting during a changeout. 2 1/2 and 3" mega press flanges and couplings have saved the day on a few jobs to make the transition to near boiler piping where threading in place would not be practical or increase the cost for the customer by a decent amount.

Not a good idea to use MegaPress on steam, since it's too easy for the fittings to sag over time. And we know what that causes……………

@Jamie Hall They were used on non-vacuum systems as well, Jamie; but Hoffman’s intent was to eliminate the valve packing so that air couldn’t enter on either a mechanical vacuum system or a vapor-vacuum system. They told me that back when I was their rep.

Packless valves were for vacuum systems.
