I adjusted the valve handle, which overtightened of the needle stem allowing it to sink too far into the orifice.What happened to your needle valve?

en... it might be easy fix, but I need to check it personally, it is hard to explain but also without the proper equipment is not easy to play around it..Hey folks. I bought a used regulator on eBay but when I hooked it up, the first stage is at 900 psi but the second stage doesnt register any pressure regardless of the knob position. I also noticed some greenish goo in the inlet port. I suspect that the internals are plugged up somehow. Any suggestions on what could be wrong? Should I try to repair it? It’s a really nice stainless Harris.
Exactly. Very informative read.The instructions seem to be the same, just worded differently. But @bettatail also has a third step that tests for leaks between the solenoid and the needle valve.
In the industry I worked in h = high pressure meaning gas cylinder input and also the high pressure gauge L = low pressure meaning regulated pressure out and low pressure gauge and the I was always plugged. I think, but am not certain, that it used to check for a blown diaphragm on suspected faulty regulator. Again, I don’t claim to know what I’m talking about.Hey guys ... just got a SS 3810 Matheson valve. It has H H I L L ports. What is the I port for, Intermediate? Should I plug this?
Indeed I finally found the reference. That port is for an overpressure valve.In the industry I worked in h = high pressure meaning gas cylinder input and also the high pressure gauge L = low pressure meaning regulated pressure out and low pressure gauge and the I was always plugged.

If it makes you feel any better, I have the exact same regulator and plugged mine as well.Indeed I finally found the reference. That port is for an overpressure valve.
I ended up just plugging it. It has been working well. Thank you for the response.
I can’t see but if the low pressure side came with a 400 psi gauge then the internals would need to be changed out to make it work for the much lower pressure used in the hobby. I wouldn’t recommend messing with that unless you are familiar with regulators and since you’re asking I’m guessing you’re not. I would start over myself. You would never be able to get this down to ten psi as it sits.Ok. This is what I was instructed to buy back then. I was also told to replace the connector valve to hook up to the tank as its the wrong type. I didn't want to go through all that so I didn't move forward with it. Now it looks like I cracked the guage during storage some how. But its 400 PSI. So I guess I can just get rid of this one as its not suited to what I need. Do you have a reccomendation so I can start all over? Can I get this done with all parts around 350?
Absolutely you can. You just have to be patient. I got my SS Matheson 3813 for $120 + $30 shipping on eBay. It looks brand new and was barely used.Do you have a reccomendation so I can start all over? Can I get this done with all parts around 350?
