    AFAIK they never published pressure ratings, but they were intended for use on systems with safety valves that would open at no more than 15 pounds on steam or 30 pounds on hot-water. FWIW, when we test these rads we pressurize them to 30 pounds.

    Thanks Frank, I figured so but was wondering due to some of the midrise building that use hot water and may be running higher than that?

    Sure they don't use steam boilers feeding heat exchangers on the various floors?
