The exhaust temperature has nothing to do with the tube temperature 
Randy.

The seals are rated at 250 degrees C maximum.

That could occur with 0 degree air temp on the exhaust of a PA, 
or 500 degrees C. You are too far downstream to estimate the seal 
temps.

What you need to measure are the seals, and I would use a 
temperature indicating crayon or paint to do so. The Fuke would 
 be a shock hazard.
