i just received my 0-3psi #33020 for the steam boiler. Now to put it to work.

I plan to take mthe pressuretropl off the pigtail and the with a T fitting abd a few brass nipples, and elbows, reattach the ptrol to one side of the "tree" abd the 0-3psi gauge to the other side. I will not touch the 0-30psi guage.



I am going to use a black iron union. that way I can get most of it together on the beanch. From the union, the retst will be breass fittings. Should I use the same sealant on both the iron and brass. Teflon and/or rectorseal #5 ?



We stil have the two-pipe, air vent system (1900??) with radiators with two supply valvers and air vents.



Thanks for the help fronm HeatingHelp and Dan Holohans books!

    Pressuretrol reattach

    If your pressure trol has a mercury bulb, make sure the bulb travel is perpendicular to the pigtail movement. Otherwise it makes no difference.  Some gauges are internal trapped and may not need a pigtail trap to protect them. Follow the mfg instructions on the pipe dope container, brass to iron should not be a problem.
