Does anyone recognize this manifold (double flame logo)? The valves are frozen and I want to find replacements.
Thanks!

    Legend Brass, Ivar, or Castanazza (sp)?

    Seems all the radiant manufacturers have used various brands over the years.

    Sometimes knowing the brand of the tubing connected can help determine who made the manifold and fittings.

    Thanks, HR. It could even be Giacomini. At this point, it might be easier to replace the manifold.

    Giacomini comes in a Legend branded. This is their logo.

    I have seen that one before but just can't place it.

    There were so many different brands back in the 90's.

    My supplier tells me it's Sparco.

    Yep, now it is coming back where I have seen that logo.

    Honeywell took over Sparco, not sure if that name is still around?
