I’m a newcomer to dispensing via a kegerator at home.
Before pressurising a keg, I have run a test on my mixed gas regulator to verify proper use.
As a test I connected my gas line to my regulator (pushes in to gas tight JG 3/8 fitting) and set the PSI to 35 after opening the valve on my mixed gas cylinder.
After around a minute I completed the test and noticed the regulator had frosted as had the gas line (only slightly).
I’m curious if this happened because I wasn’t pressurising the keg or if theres likely a leak somewhere?
It’s a new regulator so I’ll check all the seals etc but wondered what else I could inspect or if this was just a result of temperature and having no keg connected.
For context, I conducted the test in my garden and the temperature was around 15 degrees.
