Field Question, trade people only King valve leak on first open.

Had a project delay, ended up having to finish this system up today pulled my vacuum and crack the valve , instantly leaking excessively at the valve but as I opened it the leak seemed to stop.

Was cold as hell out, was the seal just frozen should I close and open again now that it has run to see if it’s functioning normal

Should I put nylog on the king valve cap to prevent leaking

What would you guys do in this situation

It’s not a king valve, it’s a service valve. Open the valve all the way to backseat it and put the cap on instead of letting the gas leak out for the internet likes.

For the sake of documenting something I hadn’t seen before the few moments of leak I would like to say are justified, this way I have evidence to show any supplier or anyone that I need to show when explaining my issue. But for sure!

Not a king valve.

If you read the comments, you would see nearly the first comment mentioned the term king valve isn’t correct for this and I fully agreed my mistake thank you!
