Tank Valve Tightness??
Posted: Tue Aug 15, 2006 5:15 pm
I got an Al 80 off of a (formerly diving) neighbor of mine and because it had not been used for several years, brought it in for a hydro, visual, & rebuild of the valve.
It was totally depressurized (and had been for years).
What surprized me was when the guy at the shop just smartly popped the valve handle with his palm which unseated the valve body and he then started unscrewing the valve body from the cylinder.
:naka:
??? Are they supposed to be just "hand tight??" I know they have the o-ring to seal them but I would have thought that there should have been more torque applied when tightening the valve onto the cylinder.
I guess my second question is: should there be any lubricant applied to the threads before reassembly. (assuming use with just air, no EAN.)
Anyone have any info on that??
Thanks!
