Who is the expert on sight glasses.
I have a 3.5 HP 80 pound steam boiler
I use for pressing clothing. 10" sight glass.
The sight glass springs a leak all the time
at the point it is attached to the cock.
Some of them last 2-3-4 months.
Some last 1 month before they spring a leak
and scares the hell out of every one. Hot steam will
do that !! Does anyone have the secret??
Thanks..
