replacing K valve

[all4scuba05]

my AL80 has a broken valve knob from shipment...seller is sending me a valve as soon as i let him know the thread size...is it going to be too difficult to get the valve off? if so, any advice? i don't have a large vice to hold the tank. while cranking the valve off..

Take it to the shop. They'll need to VIP it before they fill a zero PSI tank anyway.

As long as the tank is empty, you should be able to remove the valve by hand. No vice needed

yeah... make sure to drain the tank completly, and then you should be able to
unscrew the valve by hand.

at most, you should be able to do it with a large-enough wrench, just to get
it moving

you will need a new vip (as stated) if you tell the shop that you changed valves,
so maybe they can do it for you since they're going to have to remove
the valve anyway

I thought all Al80s took the same size valve. If so, seller should be able to send new valve and LDS can make the swap as they do the visual.

If using air put Dow 111 on threads to stop it from seizing. If using nitrox use an oxegen compatable anti-seize compound
