You're not at risk from the tank/valve. Easiest way around the problem is to keep a 6mm hex wrench with you and remove the insert before taking it in to be filled at that shop - that way only the din is there and That Is meant be be used at 3400.

That's the first time I've heard of that.... Which shop was this?

You'll die a horrible death -- send them to me immediately, so I can dispose of them safely!

Mine is 4000 psi right now..... You are talking with me right now, are you?

Ditto!! The working pressure is 3442. I have been regularly filling mine to 3600-3800 psi for the past year now. Before it leaves the factory a tank is tested to 10 times it's working pressure. Filling it to 3400 plus poses no risk whatsoever. Sounds like this guy just does not want to give you a good fill. Tell the cheapskate to fill it to what you want or you'll take your business elsewhere. As for the insert if it was not safe at this pressure they would not have included this type of valve with the insert. Also if you are using a newer reg even with the yoke style it still poses no risk. the newer yokes are able to take alot more than the first ones that came out. this is in response to the many people that dive with tanks that have a "good" fill. As a DM candidate this info should be included in the equipment portion of your DM course. I know mine has included more info on tanks, regs, BC's, and other dive gear than I will probably need in a lifetime. But then again my instructors motto is what you don't know may kill you or somebody else so we are going to be as thorough as possible.

I can only think of one reason someone would say something like that ... he doesn't sell that style of gear, and therefore firmly believes it's dangerous ... until the day he decides to sell it, then it'll be quite OK.
