you mean \"propress\" made by viega sold by rigid

those of us who have it, swear by it

they now have ball-valves for it and all sorts of good stuff

the only caveats are - fittings take more space, and on the larger sizes you need good pre-crimp rotational support, -

and, you have to cut out repairs/mistakes, big deal!! and if you own a "speed-saw"
(those motto-tool looking things with a drill bit with burs on the shank that cuts sideways, like the ryobi ss180

http://www.ryobitools.com/product/product.asp?prodid=219&prodcat=3&toolcat=4
or the dremel advantage rotary saw
http://www.dremel.com/productdisplay/tool_template2.asp?SKU=9000-04&Color=99CCFF),
then, you can always cut the pipe right at the fitting or even carefully notch through the crimp and remove the pipe intact enough to reuse with just a little emery-ing

i would be nice if someone made a little side-wheel cutting tool that would automatically notch the crimp through, using the pipe beside the fitting, as an auto depth gauge

you can also use a "fine multimaster" - it gives you enough finesse to do it right http://www.waltertool.com/multimaster_sys.html

basically any tool designed to cut out grout between tiles without damage and has metal cutting blades avail, should be able to do it

Propress

We have had ours for about a month and love it, it has cut the time to make our boiler panels by about 60% and you can't beat how they look.

Propress

We have had ours for about six weeks and love it, it has cut our labor costs for piping by about 60% and you can't beat the way the boiler panels look.
The only problem we have had is getting the supply house to stock enough of the fittings.

Itching to try it out on steam

How does the Propress work on steam? They rate the fittings and everything for steam too, I checked that.

Any opinion on how the O-ring will resist time?

The big fittings are quite expensive, is it worth it to do a replacement header with this?

Zebb...i am a dissenter.....

in propress class..."here. Squeeze this 3/4" coupling on.. ta da! Hurray! wow ! I am Bedazzeled with the foot work....buh ,in pro press 101 ,with 3" 4 "fittings all of a sudden sh happens....the pipe and fittings after beacoup d'alignement and uni strut clamps etc etc dont square up like normal fittings ....they "Wander" and it is depressing To ME. i like my work to look like well how Did he do that? or "I didnt know you could put two tees so close together or Dammm that looks straight!" `1"&1/2 2" they are a bit better although they too exhibit some vagarity. Smaller pipe 1"3/4" they sorta seem ok..the other thing was ," we cant get this" "or... that " so we have to do this and they dont have ... i drag a book i have on the stuff out and say ,"well, You say they dont make a 45 ? well ,..What is This? and ,"you say they dont make street adaptors? Then What is This? " it put me off the the thing entirely....the temp probes had to set almost out of the stream of flow on a Straight run on the injection supply and the return to the globe valve...and the closely spaced t's looked like a Third graders idea of closely spaced t's... due to the fact that you Have to put them Xpipe diameters away just to Hit a round spot on your K copper. i'd be really leery of recommending it to someone who was off to do a large injection system and was relatively enamoured with straight being a Good Thing. The two inch to the floor model recirc pump, Picked IT up off the floor and cocked it off the ground at an angle! Foolish me ..... had no idea i had to bolt it to the concrete pedastle it was sitting on ,held there by gravity.... Yah sure motors should be bolted down as should floor mounted equipment ,however, that is not really where i am going with this...if the two inch which stays relatively straight as it has the same phyisical chareteristics as the 3/4" 1" 1/&1/4 1/&1/2 and it could lift an End Suction Centrifical pump off the ground,... how would you feel to see it snatch a 1700lb boiler off the floor with a piece of 4" that puts the same stress and strain on a header as balancing multiple pumps off a supply or return header with out any additional support and totally disregarding bending effect on the boiler fitting ....( not that i have seen many boilers that have cracked directly at the tap or fitting) however that isnt the point at the momment .. the thought that it Could....lift a boiler off the ground or knock it out of alignement. I Just hate the whole idea now, entirely.small fittings eh ...i am quick enough and i dont have to go trashing on my new work ...i was all set mentally to do this really Kick **** looking header too! thats what really irks me. i spent quite a lot of time thinking it all out and rounding up most of the pieces. The more i think about it, the more i hate the thing.......i know that if you havent anything good to say, Then ,You should say nothing at all........well...consider that a vote anyway for the dissenting side.

the o-rings are fine as long as...

the copper itself stays together, after reppppeattttttted steam hhhhaaammmmmrrrring!!!

the slightest deformation of the copper and it's over!!!

remember the shuttle challenger - the o-rings on the solid rocket booster segments hold back temps and pressures, of a chamber that develops 1.5million pounds of thrust, but just a little freezing condensation, deformed the metal ring surrounding it slightly, and the rest is history!!!

how good is your insurance????
