^ No idea, but thanks again for the help. That teflon trick was pretty slick, I wonder if they sell a smaller width version.

So this is what I end up with, I was trying to add in the Parker H3 but I'll do that tomorrow, maybe even pick up a solenoid. The majority of the time was me wrapping and cleaning and re-wrapping those gauges. I could never get it right until I move the body of the regulator and not the gauges. Argh, so very tired now.



g' night all

Those holes and that corrosion are likely the culprit.

Is there a place online where you can buy just the HP diaphragm assembly?

Is it even worth it going through all this trouble?

I haven't found any online sources; I always just go to my (somewhat) local welding store.

Depending on your luck though, the repair parts might end up costing more than buying another (used) regulator.

Not in my opinion.

A bit confused on step 2,

1. I don't have a solenoid hooked up, skip that part right?
2. Why would you want the needle valve to be open? Wouldn't you release the Co2?
3. If you disconnect the regulator from the *closed Co2 tank, that 800 - 1000 psi that burst out. I did it before and it's like a BANG.

if you only want to test the second stage, skip the solenoid. step 2 also test the leak of body kit (from the regulator to the solenoid).

There are two sub steps here,
1. needle valve open, solenoid close, so if solenoid has internal leak, the co2 can vent out from the needle valve and PSI reading will drop.
2. needle valve close, solenoid open(power on), to test the post body for leak up to the needle valve(for needle valve that can be shutoff and stop the air flow).

I think I did mention turn loose the CGA nut slowly and let the co2 escape from first stage, so no "BANG"

let me check my junk box, I remember I have a couple dead VTS 250 regs, one of them is front(second stage) diaphragm damage, the back diaphragm can be used for replacement parts.

or you can send me the front diaphragm so I can revive mine.

BTW, a new system, Top of the Matheson hierarchy, a 9400 stainless steel.

Nice Ultra Line.

That is the CLEANEST tape job I have ever seen. Kudos to you.

thanks, Josh, and there will be a couple more projects, a new swagelok regulator and a new Chiyoda seiki.

picture of the Chiyoda Seiki(千代田精机) with parts,



swagelok gauges, 0-60psi and 0-3000psi.

I'm not even going to google how much that Matheson 9400 cost. Don't want to know.

Hey Betta tail, so I talk to Swagelok and they mention Brass with SS isn't ideal. I'm stuck with SS fittings tho, they told me it should be fine because it's not outside etc.

I'm sure you have a ton of experience with brass/ss and I know I ask you this before but, just to be clear, teflon and less torque right?

I just rig this up to test the first stage, disregard the nasty looking brass. I'm waiting for my Swagelok ss tee fittings.



Quite the learning experience with teflon tape, a lot harder than it looks.

Ya know what's silly?

If you buy the gauge from WIKA, it comes in a plain cardboard box. Order the same gauge from Swagelok and it comes encapsulated in foam...
