Just got this scott specialty regulator and am a little unclear about a few things namely-

Despite the listing saying 75 psi and 3000 psi the gauges I received are 100 and 300 psi - I hope that these are two low side gauges and not indicative of my second question which is is this just a low pressure regulator?

Here is some info for your regulator. 51-218B-580

The max working pressure for that reg 50psi and the max cylinder pressure gauge range is 4000psi. You may just need to find a different gauge to replace the 300psi.

Ebay #321353984120 looks like it might be a good fit for a HP gauge. Technically you don't have to have one but it will tell you when your tank is getting low or empty.

thanks for the info guys. I couldn't find that data sheet nor could i fathom why a dual stage regulator would work with such low pressure. Seems like they just threw whatever couple of gauges were handy in when they shipped

Pretty much, but for $25 you can't ask for much.

I once got a concao 432 ss for $25. It's all about the waiting game.

One thing to note is the gauge that has a reading when it is not on a tank. Normally that would say the gauge is ruined. If it thinks it has pressure now, how can it tell you what the real pressure is when you connect it?
I would not rate this seller very high as even a blind guy can see there is a problem.

It's hard to tell if the LP gauge is off 0 because there isn't a picture straight on. It might be on 0.

I think it's one of the working pressure gauges with a minus value. Meaning it can read to minus - 30 psi too. I have a dual stage with this LP type gauge.

Here is a better pic - it can measure a vacuum

Another question - is there supposed to be a relief valve on the first stage (rear) of the unit shown here?

Sometimes they come with relief valves. Most people feel they aren't needed for low pressure CO2.

 

[nicholz]

I see - if not a valve what about a cap or plug of some sort? I can provide a better picture if needed

This is the port hole in question

It's probably a 1/4" NPT port. Bass plugs are like $3.

Do you have the real specs on this.?? Checking @ Scott, and the gauge fubar you could have a somewhat unusable (or at least w/ less flexibility) regulator..

They have a 2-15lb model..........

I assume I have to do something about it so brass plug it is thanks again Rd
