Obsolete Part, really??

I have a Trane hot water boiler, installed by previous owner in 2008, and I’m thinking it was manufactured in 2007.
The problem is the temp gauge went out and the supply house said “it’s an obsolete part and no longer available”…that seems rough for a boiler that isn’t even 20 years old

Any ideas on finding a replacement or am I SOL?

It’s a combination temp/pressure gauge and I have included the boiler model and part list in photos.
thanks for any insight you can provide

    I can't say I'm familiar with Trane boilers, I didn't even know they made them. That might be made by a different manufacturer and re-badged as a Trane. Either way that gauge is not a part that has any effect on the way the boiler functions. I would see if you can match it with a universal replacement Tridicator. Or just tee a Tridicator into the boiler piping.

    As to not believing that something only 16 years old might be hard to get — have you tried getting parts for pretty much any car you name manufactured between about 1995 and 2020? Chap I know the other day was trying to source the engine computer for a 2015 Nissan… nope. No such luck. Push it off the bridge (actually, he got lucky and found one in a junked Nissan which worked…)

    I can look up your serial number and see that Burkett HVAC installed that boiler. I can also see that the model number TGBWF090A93AVA is no longer in the database as something that Trane ever sold.

    That part number is the same as https://www.supplyhouse.com/Bluefin-TDB25-75-BK-2-5-Tridicator-1-9-16-Well-Back-Mount-Temperature-Pressure-Gauge-0-75-PSI-30-Degree-to-250-Degree-F

    After you make that expensive repair and you still have the same problem, What will you check next?

    That very much looks like it was a european boiler they slapped their name on. Also googling those numbers, looks like they used their own part numbers

    If its anything like Weil McLain used to do with capillaries to compression fittings and bushings, it's likely they leaked over time and revision models probably offer a standard tridicator gauge piped externally.
