Want to DIY a co2 reg

Anthony,

Thanks for the clarification. Now, lets check for understanding...the PDF for the Victor VTS 250 series indicates the following:

Is the working pressure of the manifold you mentioned, the range I see in this picture? For example, the 250C has a range of 4-80psig and the 250D series has 5-125 psig.

If my understanding is correct, a lower gauge that goes up to 100psi may work for both of these series since, for our purposes, we will never go past the 100psi?

In other words, can a 100psi lower gauge be installed on a 250D series or is a 200psi a best choice?

Thanks!

I do not believe I mentioned a manifold; only the delivery pressures.

Yes.

Yes, it can. You can leave the 200 PSI gauge on as well; I use a Victor that has a 200 PSI low pressure gauge and it increases in (minor) increments of 5 PSI and major increments of 20.

Aside from eBay...what's another good place to find good quality low pressure gauges with a maximum 100psi reading?

Also, what is the size for the ports in the 250 series where the gauges connect to?

Thanks.

You may be able to find a local welding store that carries them.

As for the sizing, don't quote me on it, but I believe most are 1/4" NPT.

What's considered a good price for them? Thanks

That's hard to say; I've seen decent ones go from \$10-20, but stainless steel ones can cost significantly more.

I'm looking over the PDF file for the VTS 250 series...

I boxed in red what I think is the maximum working pressure for each model...Am I correct?

For example, the VTS 250D has a working pressure of 5-125psig. So, in the event that one wants to replace the LPG the best choice is to go with one with a maximum 200psi... Correct?

I've noticed that some people use 100 psi or recommend to use this gauges...isn't that a risk? What if one accidentaly goes over the 100psi mark...the gauge will break. Right?

I do not see anything.

This is correct to some degree; you can replace the low pressure gauge with one that is lower than the maximum working pressure (see below).

Yes, if you go over the 100 PSI mark accidentally, while the regulator itself will be fine (since it was designed to handle that delivery pressure), you will break the low pressure gauge.

Picture has been posted.

So...what maximum LPG is considered to be the best to give you the best control over reading pressure?

Thanks!

Yes, the boxed values represent the working pressures (minimum and maximums) of those particular regulator models.

I would say 200 PSI should be the maximum reading on the low pressure gauge (not the maximum delivery pressure of the regulator). Anything higher, and it will become difficult to see how much you are increasing/decreasing the working pressure by.

I'm so about to throw this reg away...i purchased this VTS 250d on eBay and have been trying to remove the LPG and inlet but its practically impossible. My hands hurt from trying to turn the wrench but no luck. Any suggestions? I do not have a bench vise.

Thanks

Check to make sure there is no (red) Loctite around the low pressure gauge.

If you do not have a bench vise, you are in a bit of trouble. You will probably need one to get it off.

You can try a mechanic, they should have the tools.

There's is no red loctite residue...ill try and see if my local mechanic would do me a favor. Thanks Anthony.
