9851780 The Gauge store says this gauge is not suitable for a steam boiler. Any advice on this type of gauge. I know a lot of you promote LP gauges from this company. The high temp limit is 140 degrees on this gauge. <img src="http://www.heatinghelp.com/file:///C:/Users/Mark/AppData/Local/Temp/moz-screenshot-1.png" alt="" /><img src="http://www.heatinghelp.com/file:///C:/Users/Mark/AppData/Local/Temp/moz-screenshot.png" alt="" />

Steam gauge

That gauge cannot be used on live steam BUT if you have a siphon between it and the boiler it should be fine. I have a gauge that is in the same series mounted on my Burnham boiler as you can see in the photo below. If you look behind the BX cable you can see the original 30 PSI gauge which has an internal siphon built into it.

They told me

to get the gauge and pressure controller way up above the water line.  This is how I did mine.  When the boiler is steaming the pigtail gets hot (more than 140 F)at the bottom, but the top stays at room temperature.  Gauge/Snubber/Valve stay about 70 F all the time.

right .. what bob said ..

the pigtail protects it from live steam .. there is always a buffer of water in the pigtail .. and this is exactly why we don't use a straight nipple ..
