The largest drool puddle at ISH

at this press fit fitting system booth. Imagine a push together copper fitting without the need for that nutbuster, hernia-master squeeze tool!

This fitting looks an awful lot like the fitting used to connect water treatment plastic lines. It depends on an o-ring and a gripper ring. A tool reams the OD and scribes a line to prove insertion.

Seems too simple to be true. Sizes up to 2"!

I did see one fellow carrring a piece with the o-ring half inside the pipe and half in the fitting. Bummer. Perhaps a lackluster ream job?

Maybe a pipe with an OD issue? That never happens!

Think I'll wait till Miline has about a 5 year track record with the system :)

    Saw those too Hot Rod

    It looks like the equivalent of sliced bread if you catch my drift. However, if I had a few jobs out in the field using those fittings I don't think I would sleep too well. Call me old fashioned but a mechanical joint is still a plus in my book. I'll keep dragging the crimper around for the very small time savings involved.

    BTW, We just finished a job with over 2,600' of 1 1/2" copper and countless fittings. Had two leaks, one was not crimped at all and came uncorked at 25 PSI test pressure with me directly in front of it in a 2'x2' tunnel. (Don't ask) The other one was not crimped properly. I still have to ask Andy and Mark how you "crosscrimp"? a ProPress fitting.

    I'll stick to the Propress

    One of the questions about ProPress has been the rubber exposed to the air. If you look at the PP fittings, the o-ring is captured in the copper and not exposed to the air, I don't see this happening with these fittings.

    Any idea what temperature it can take ?

    By the way the Stadler press fit bottle opener came in Very handy on the Chowda bus.
