I am purchasing two 80 Cu.Ft. U.S. Divers tanks from the 70s to early 80s. They are the black tanks that say professional on them. They had a dual manifold that has been removed. Are the Sherwood K- valves a good choice for these tanks? Are they rated at 3000 or 3300psi? Thanks, Eric.
regarding the sherwood k valve what size o ring do i neeed to order to replace the existing one when it gets worn ,as i have a few of these tanks and need o rings
Hello Nathan, here is the web link: http://www.scuba.com/scuba-gear-297/230210/Scuba-Deluxe-Tank-O-Ring-Kit-and-Key-Chain.html. You can put this on your key ring or put it in your repair kit so you will always have a few with you.
Looking at buying Sherwood K Valves. There are different pressure ratings available, pretty much for the same price. Why wouldnt one just buy the highest rating (3300 psi)? I use 80 cf alum tanks, standard stuff. Thanks.
The rating of the valve MUST match up with the tank itself. Its not that you would get more PSI out of your tank having the 3300 PSI valve, this is a safety thing. An example would be if someone filling your tank gets distracted instead of your tank rupturing a small replaceable burst disk will rupture. Not having the correct valve with burst disk not only puts you in danger it puts the dive shop you use for tank filling in danger.
