CO2 Regulators HELP!

The 'M-3' gauge has a Clippard needle valve on it. I see no other brand names on the regulator.

I will ge back and research the warnings about "end-of-tank-dump" issues and diaphragm damage.

Bob, can you direct me to "end-of-tank-dump" and how it can damage the internal diaphragm of the regulator?

Thanks..

(guess I missed it..) :(

80gJoe,

Have you tried using your broken regulator? My wife has a lot of experience with compressed gases, I had mentioned your problem to her, she said it is much more likely that your gauge is broken and not the diaphram.... with the M3 regulator, the needle valve does not unscrew? Checkout the MNV-4K2 valve from Clippard, see if this is the same... if not, they may have went really cheap on your needle valve and this is the cause of problems... I use cheap, (and I mean _cheap_ ~ $45-50) regulators and have never had issues...:rolleyes:

btw, is M3 back? I placed an other with them about a year ago, I thought they had closed shop: voicemail full, no one answering phones, etc..
 
We had the same problems with M-3. We placed an order for a complete CO2 set-up and we got no response. Oh, we did get a reply months later after we told them several times to cancel our order. They asked if we still wanted our order... Way too late...

The M-3 (sticker on gauge), we have that is bad was from Florida Driftwood.

The AquaMedic (fixed pressure) regulator is from BigAl's and it's working good.

The old M-3 is stuck at over 30psi on the gauge. This made it very hard to control the CO2 flow rate and it kept drifting a lot. I think the diaphragm was damaged.

All I know for sure is that the regulator broke when the 'end-of-tank-dump' happened...
