Well, I did it now.. I couldn't figure why my last 5# tank lasted 1-week. No I just found out... The o-ring between the regulator and the tank is gone. Went to beer distributor and Lowes with no luck.

Anyone know where I can get an o-ring for this quick?

Thanks,

Ted

paintball stores should carry them.

you should keep some extras on hand. When the pressurized co2 is released its reaction is to freeze, a long exposure of very cold temperatures causes the rubber o-rings to weaken and crack.

I'm not sure how often they need or should be changed with a tank only releasing very minor amounts of co2 into a tank but when I used to play paintball, I would change out my o-rings fairly often because of that.

I took my o-ring off my paintball tank and it is to big for the MA957 Milwaukee Regulator. The recessed area is slightly smaller than the standard paintball o-ring.

You sould change the "O" ring /gascket every time you remove the regulator from the co2 tank,or buy one of those "Perma seal" washer like o rings that Rex sells.
If you know a Hydroponic store in your area they should carry the plastic ones.

Any welding store or home brew beer store will carry standard sized washers. In fact when you get your cylinder filled they should give you one.

Rex,

Will your MK I Perma-Seal fit the MA957?

Thanks,

Ted

Sorry to Hijack, but I have a quick C02 O-ring question:

I just bought a pack of six when I got both of my tanks refilled. 3 white and 3 Black. Was I supposed to use one of each? Is there any reason why there is the same number of the 2 different colors?

Thanx!

Now back to the regularly scheduled programming......

 

[distrbd]

I use the white ones,if they are the same size and feel the same density use the black one too,I have never seen any black o rings for that purpose.

I would suggest some teflon tape around the threads for a better seal as well.

Sorry Rex, I meant the non-threaded "Like the MK I". Will that work?

 

[Rex Grigg]

Please explain to me how you would think that Teflon tape around the threads of a CGA 320 fitting will help the seal?

The CGA 320 fitting doesn't seal on the threads. It's a flat compression based seal. On most regulators the nut is freely sliding on the stem of the regulator. So just that fact alone would convince most people that a CGA 320 fitting doesn't seal on the threads.

In fact CGA specs call for NO Teflon tape to be used on the threads of the CGA 320 fitting.

thadius65: I have heard from a couple of people they don't fit. But I've not had the chance to test that myself.

Thanks Rex. I will call Milwaukee today to see if I can get a replacement.

Retoid -- Teflon tape is worthless on this type of setup. My brother in-law is in the plumbing/HVAC business and he said that the seal is created with the o-ring and the threads only purpous is to pull the regulator into the o-ring and the tank orafice. If that isn't doing its job, the tape wont do anything.
