Is there really a "steam" pigtail?

I am replacing the 90 pigtail for my pressuretrol with a straight pigtail and noticed 1/4" black pigtails for 1/4 the price of something labeled a "steam" pigtail. Is there really something special about a "steam" pigtail for this application?

    The black ones are probably steel, brass pigtails don't clog as easily and are easier to clean because they don't rust - it's worth the extra money.

    You should always use brass -- it doesn't clog or corrode quite as fast

    I will third on the brass, my old boiler had steel and it was a pain. The brass is much nicer in the long run.

    Please excuse me if I explain this poorly. I'm fairly new to steam so please be patient. Okay so I have a similar situation to the original post. The settings on my pressuretrol are at the minimum and the system is working without any issues (thankfully). My "problem" is about the gauge. It always reads 10-12 psi which has to be wrong (it's the original gauge affixed to the front of my peerless boiler). Can i install a brass tee with a separate pigtail from the pressuretrol and install a new low pressure gauge atop of it?

    @flyers03 - Better to install it on the same pigtail as the pressuretrol. If you remove the 0-30psi gauge you will be in violation of the codes. If you feel like making it right you can remove the 0-30 and clean out the tiny hole in the brass snubber with a needle. It should work after that (for a little while) until it gets plugged up again.

    Captain Who - so instead, you are saying to install the brass tee above the pigtail and branch off the pressuretrol and new gauge. i'm not going to remove the old gauge so i continue to meet the code requirement.

    Yes, exactly. That's the way I have mine and it is working very well.
