Works as advertised
I needed something to indicate air pockets in my latest experimental solar thermal system. These do the trick. It can be hard to see if there is liquid or air, when the liquid isn't colored. The way I mounted them, about 1/3 water remains when the water is gone. Hence I can see the air, when it is 2/3 air and 1/3 water. Unless you use a colored liquid, you might want to consider that.

Like insurance for my trucks.
It takes seconds to lift your eyes and see the top radiator tank has water in the morning. Many drivers are to lazy to climb the side ladder on 30 ton water trucks, remove a cap and check the water level. I'm sure anyone could guess the results of running a Cummins without water & overheating the engine. Anyway, the drivers have said it saves time in the morning and for the small cost it could save hundreds of thousands in motor repairs, down time & lost contracts. These sight glasses are great & I highly recommend them. P.S. The green water stands out so bright I'll know if the additive has been overlooked on servicing.

It's Perfect for Surge Tanks On Trucks and Buses
Perfect replacement for any OEM Surge Tank sight glass. Larger view of the fluid level with a clear indication compared to the old conical type. It's a win..
