Stupid question alert: what size o-rings for hoses?

[Mark IV]

I want to replace some over-tightened o-rings on a used reg i just got (but am not in any hurry to do a full service on yet). I'm thinking that I'm looking for .010 for LP hoses and .011 for HP hoses ? Is that correct?
And, where's the best place (cheapest shipping) to order a small batch of them? I'm probably looking to get viton, but not necessarilly..
Thanks in advance for any solid info.....

Vintage double hose will also have them in small qty

if you only need a few though, your LDS may throw you a bone

Your sizes are out I believe.

010 hose second stage end
011 first stage end 3/8 lp
012 first stage end 7/16 hp

The 012 "needs" to be duro 90 as it's hp.

If you're in the US and want larger quantities then here.

But, as posted above, I'm sure a polite conversation with your or any LDS might be the way to go if you only need a few.
