    With pro press you don't need a burn permit or anyone on fire watch on some jobs. Plus you can make the connection with water in the pipe.

    I'm excited for refrigerant press fittings cause then you can make a connection while refrigerant is still pissing out.

    Would be handy for when you're making a repair and the service valves don't hold.

    Yes then no evacuation needed if the gas is flowing out keeping the air from getting in.

    As they should be. Some only have operating pressure ratings to 125 psig, other to 200. As you know, in a high rise setting, operating pressure can easily eclipse those ratings. That doesn't take away the usefulness of these piping systems in light commercial applications.

    They probably use EPDM and if it isn't exposed to sunlight it will last as long as the pipe

    for the mcmaster carr book:
    epdm is rated from -40 / +212
    listed as applicable to steam, wasser, acetone, ethanol, and nh3
    so, i guess steam up to .125#

    this is informative

    I don't have a big enough use for propress although in a pinch I can rent the press from the wholesaler

    I also am concerned with oring integrity life span
    you know when led bulbs came out the manuf claimed a 25 yr lifetime - Ive found 3 yrs to 10 now just having bulbs I got 10 yrs ago fail so that's approx. 1/2 to 1/8 their advertised life span - I see now some are saying 25000 hrs = 17 yrs based upon 4 hrs/day 365

    I won't be surprised when propress orings start failing after 10 yrs especially on steam/hot water lines

    with all the blended refrigerants being used now, wouldn't you have to pull the charge out and weigh it back in if some escaped anyway?

    It depends on the fractionation potential of the refrigerant. For instance, R-410a is a NARM (near azeotropic refrigerant mixture). So when it leaks, it basically leaks out in equal parts.

    I thought this thread was gonna be an infomercial on Cuban sandwich makers...Oh Well. :)

    Anyone remember vitriolic PVC? How did that work out? I'll wait and see because I remember that and Alum wiring and polybutylene too.

    My service business makes money fixing things that leak, break, or disintegrate. My techs get paid very well to make repairs. Why fight progress? If a building owner or an engineer specifies or approves it, we install it.
