Adapter 1/2"-20 UNF to 1/2" NPT?
Adapter 1/2"-20 UNF to 1/2" NPT?
(OP)
Could anyone, please let me know where I could find out the above adapter either Brass, Aluminum or SS material?
Also, any suggestions on a good vendor of sight glass/liquid level gauges?
The liquid is H20, T~68^F, Pressure < 20 psi.
I checked out McMaster-Carr (e.g. part 3280k49), Grainger but they do not have exactly what I need.
Any comments are more than welcome.
Thank you in advance!

Sight glasses? Ernst: http://www.johnernst.com/

The adapter is for a liquid-level gauge (sight glass) which has these 1/2"-20 UNF connections. The sight glass will be installed on the break tank (open to atmosphere), approximately 60" H.
I briefly checked out John C. Ernest web page, it seems that they could have something better.
Once again thank you for the help!

Sounds like you are going to find a gage that fits what you have, much better idea :)

We will go with one of John C. Ernst liquid-level gauges.
