permaseal fell apart..


so I am in the middle of my leak test by bettatail and when I moved to stage two and removed my regulator from my co2 tank the permaseal fell apart. nothing is broken, the rubber washer just worked itself loose and now I have a loose brass washer and a loose rubber washer and the part it used to be seated on still allen wrenched into my co2 tank. is this normal? should I just remove the rest of my permaseal and go with one of my nylon washers? I hand tightened the reg to the tank and then twisted the reg a inch or so to fully tighten it up - did I tighten it too much or something, thus twisting the rubber around? not that impressed (of course it was only $5, but still)

I had the same issue unfortunately. The only thing I can really think would do it is overtightening either into the cylinder itself or onto the CGA320 connection. I also found it impossible to reconstruct the permaseal and just ordered 2 more. Granted, they're just sitting around until I stop being lazy. The little plastic seals work just fine temporarily.

Thanks for the fast replies - this site is awesome. So you are saying just ditch the brass ring and I will be good. I wonder if there is a chance of the rubber twisting up without the brass retaining ring and forming an inconsistent seal? I think I will just use one of the nylon washers and ditch this $5 POS. I mean how are you supposed to correctly use permaseal - because I don't feel like there is a lot I could have done differently.

Hi eatfood,

+1 for nvladik's comment. Mine separated and I just put it back together and it has worked for 3 years like that with no leaks.

Most of us stick with nylon washers. They're very simple, and very cheap.

I tried a permaseal once. It ended up cracking. Probably my fault, but then I was (and am) used to the "tighten the crap out of it and you're golden" nylons.

ha ha - yes the ol tighten the crap out of it. I swear I did not even tighten it that much and this happened. oh well I will try the rubber washer and if that does not work I think I have something like 3 brand new nylons hanging out from not ordering the cga that I really wanted - which I still cannot find - 2" chrome plated.

The standard Victor chrome plated CGA-320 is 2".
nipple: 0985-0008
nut: 0985-0031
washer: 1408-0065

A quick Google search should reveal several suppliers.

If you have 2 1/2" gauges, you may need the 2 1/2" nipple...

If you want a 2 1/2" nipple, you can order one from:

^ down at the bottom where it says cga parts.

That's normal. The permaseal is 3 separate pieces. Just reassemble it and it should be fine.

^do you have a trick for putting all three parts back together or do you just ditch the brass retaining ring?

No just reassemble it. . I'd have to look at mine to give you further direction. It's been awhile.
