|Coverfire||That's what I was asking, thank you. The seller I bought it from called it a 3818 but the regulator tag said 3810-580 which I thought that indicated the indivudal model. That is honestly more preferable because the 3810 has a more useable range for planted tanks.|

The arrow is pointing to what you've got. The other string of numbers is the build number.

|Coverfire||Any thoughts on whether the tag that says 3810-580 is for the specific model number or just the series it is in?|

the matheson 3810 is a 100psi regulator. it came with a 200psi gauge.
the 3816 has a 400psi gauge.
(google matheson 3810 and look for the pdf)

|Hoppy||A 0-400 psi output regulator is not a good CO2 regulator, for our uses. We need to adjust the pressure to 10-30 psi, which would not read at all accurately on a 400 psi gauge. You can use a lower pressure gauge, but then you stand a very good chance of overpresssuring it and ruining it.|

The bay ID, western stainless steel nipple and nut
|05-29-2011 07:51 AM|
Stainless CGA320 nipple (>2"): $24
Stainless CGA320 nut: $24
Stainless in-port filter: $13
All plus shipping.
Pm me for the website.
COntact customer support at Matheson and ask them for the proper part number. Stainless is more expensive than brass generally speaking. But a stainless gauge (new) will run you about $50. You can try to find a used one, but good luck...these stainless units are harder to find. They are not like a model 8.
Sometimes the replacement gauges will not match exactly. If you're a stickler like I am, you can replace both gauges at the same time and save the good gauge for the next vintage regulator you pick up.
Again, PM me if you need any help.

You can get the cga 320 nipple and nut from airgas for under $10. If you want the stainless steel nipple and nut, go to evil bay, the price is about $40-$50.
The LP gauge, it is hard to find a stainless steel one, probably you can order it from airgas, not cheap.
if you want a regular brass 0-400 psi from evil bay, have to wait until you see one.

|Coverfire||I thought about it but my local shops probably don't stock it and I am afraid that ordering it might be a bit pricey. I'm not opposed to finding a used one and have been scouring ebay for one.|

|jkan0228||Maybe go to the wielding shop for the gauge?|

Matheson 3810 Build
I recently acquired a Matheson 3810 stainless regulator, however it does not have a low pressure gauge and I need to switch out the stem on it (cga 580) to a cga 320.
Where is the best place to obtain a low pressure gauge that is a 316 stainless Matheson gauge with a range from preferably 0-400 psi because I would like to keep it as original as possible?
Additionally I would like to find a short stainless cga nipple and nut because I only have a 5lb tank and I am worried that it might tip over from the weight of the regulator with too long of a stem. I am having trouble locating this and considered using an adapter but it would only add length to the setup.
After I finish with the regulator I will likely piece together a post body kit consisting of a Clippard Mouse solenoid and a Swagelok metering valve. I would appreciate some input on this and the best method of constructing that setup.
