Yup, those appear to be the same.
not trying to throw a wrench into this, but aren't the ports on HB regs 3/8
After the reg, it is just tubing. You can find a fitting to hose barb in anything you need.
Now Does anyone know if these tool regulators have anything about them that will prevent them from being useful as a secondary?
beerthirty - some primary regulators only have a low pressure gage. It's not the least bit dangerous, just harder to tell when you are running out of CO2. You might be able to install a high pressure gage if there is a port on the side opposite the tank connection.
Its not so much the regulator reading that makes me think its a low pressure regulator,but the fact that the adjustment screw is cranked all the way in to get the 60 PSI.
KegKits has some good prices, and if you need a large amount of items it is run by Tom Hargrove, who is one of the guys that has quite a few auctions on ebay. Just call him and tell him what you want and see if you can get a package deal.
American Science & Surplus still has these Perlick secondary regulators. I just bought three.
Thanks especially to kvh and TheFlyingBeer for your pics and parts lists.
