SGHP-50 Plain Sight Glass, 1/2" MPT, Nickel Plated Steel, 1750 psi, 0.94" x 0.78"

I put this in a mustang T5 transmission to check the fluid level.

Perfect flat sight glass replacement for the OEM Mack LEU model coolant tank.

These are good quality sight glasses. I have been using them in a gas setup under 50psi. They are solid, well machined and finished. The inside of the glass isn't polished as well as it could be and I would ding it a star for that but for the price. I bought two of these to go in a 4-way as a sight glass. I have had no leaks or other problems yet. I would recommend these for anyone needing a similar setup.

Product seems well made, and is easy to see through. I installed this in a dessicant housing for an air compressor, and it holds up great with no leaks. Threads are clean. Glass seems to be nicely fused. Will buy more for other projects too.

This is a very well made and solid sight glass. Threads are prefect, and it’s obvious that it is very heavy duty I would buy it again in a second!

1 worked good, but the glass cracked on the second one immediatly and leaks.

Good service exactly what we wanted

Perfect transaction
