Vaccum-pressure gauge source

I need a steam rated vacuum pressure gauge, something in the order of 30"Hg to 30 PSIG. I can find gauges that measure that range but they are rated to 140F ambient. The old gauge did not survive boiler replacement.

Thanks to the help here, I had my 1950's era American Standard 388k BTU boiler replaced with a Utica 262k BTU steamer supplying a 1907 Eddy vacuum system (the crown sheet had rotted- kinda hard to draw a vacuum if your boiler is steaming away to the stack). The new boiler had its hardest test overnight, outside temps were about 0F and it kept us a cozy 65F indoors, most radiators weren't even fully filling before t-stat was satisfied (this is an orific system and slow filling seems par for the course- although they get steam pretty fast). I have yet to see the system bounce off the vapourstat, which is set at 8oz with a 6oz subtractive diff.


Here is hoping to a good year for all the contributors here, you have all helped me more than you can know.
