DDGA0120-5 Female Adapter Reducing Fitting Sweat x FIP Connections, 1/2 X 1/4, Copper

Hard to find fittings delivered fast and at a great price ! Can't ask for more !

Perfect fit for a thermocouple temperature sensor.

Nicely machined copper adapters. They were pricey, but I got 20 extra I don't know what to do with. If someone from Amazon reads these, we can make a deal:-)

I used these to neck down from 1/2 inch copper to a 1/4 female pipe for pressure gauges in my air lines so I can see pressure at a glance.
