Perma-seal


I think my perma-seal isn't giving a good seal anymore after 4-5 swaps. I did a swap of my co2 tank this morning and I could hear hizzing sound coming out, I disconnect and make sure everything is tight and still I could hear gas is coming out. I have a couple nylon washer, so I used it instead and it sealed perfectly. Are there any better quality perma-seal or basically all the same? I probably will only use a new nylon washer from now on.

It might be cheaper to just use nylon washers; when you get your CO2 cylinder refilled, you can ask the shop to give you a few spare ones too. They are relatively cheap, so I would not bother purchasing/looking for another Permaseal.

Yup, I guess thats what I am going to do, they charge me $1 for one but thats better than losing a tank of gas.

That's expensive; I thought I was getting gouged at 50 cents for one.

The o-ring in the permaseal may be out of place or damaged. Inspect and/or replace it..

permaseals can break too, washers are the way to go.

You can find a pack of 10 nylon washers on Evilbay for $4-5. You can realistically re-use the nylon washers at least a couple times, so 10 should set you up for life.

I saw there are 2 types of washer sold on evil bay. One is the regular nylon washer, and there is another seller selling a pack of 25 fiber washer, any difference? I use nylon washer.

The ones listed as fiber are the paper type and they suck.

I ask because I'm used to the nylon type. When I tighten down the cylinder nut, I use a lot of force to make a good seal. When I use a Teflon washer, I use too much force and have a heck of a time trying to get the washer back out of the nut when its time to swap cylinders. I guess you don't need much force with the Teflon type?

I use perma seal and always break too w/ too much force. Personally, I prefer perma seal. I also use nylon when I couldnt get perma seal replacement right away.

Fiber washers need to be replaced with each tank. As long as a nylon or Teflon washer/gasket is not damaged you can reuse them.

I usually do not go by size, since if you mention "CO2 nylon washer" the seller should know what they are already.

In any case, I measured mine, and they are about 3/4" in diameter and 1/8" thick.
