G'day,
Got to thinkin' about these valves and thought I'd send in a message to see if we could figger out how to do a cursory check before
they are installed.
If there is a machining problem with the brass valves we could thread one line and nut down into the valve finger tight which should
bring the flare in contact with the seat and the line should not move.
If the line moves the problem could be in the valve:
1) the inverted flare in the valve is not "tall" enough
2) the threads are keeping the nut from turning enough to force the line into contact with the inverted flare
3) the double flare on the line has been squashed so badly it won't reach the inverted flare
Anybody got any other ideas?
I would suggest the vendors check these valves before they ship them to customers.
Regards,
Rob M.
