Glass Sight Tubes

Any information on where I could purchase small glass sight tubes for boilers and fittings for them would be greatly appreciated.
Thank you

Depends a LOT upon what size you need.

I can get you a basic (no valves) US made sight glass set in 1/4"-40 (w/ a 3/16" glass) for $17.50 plus shipping. Or I can get imported ones in either 1/4"-32 (3/16" glass) or 5/16"-26 (note: NOT 5/16"-27) w/ a 1/4" glass for $40.00 ea plus shipping.

A 1/8" npt glass set with bottom valve and drain should be available from AMES in Florida, but I don't have a current price for it.

Thanks
I'll get back to you on the sizes when I get into the restoration. I have a vintage engine with power plant along with a generator and lights powered by the generator. It is all mounted on a 36" square wooden platform covered with a printed sheet metal. The engine is in good condition but the paint is almost black. If I brush any cleaner across it the paint crumbles off. Repaint or not?
Thanks again!
