I'll see if Home Depot has any o-rings that are the same size but a little thicker.

you could do that. But as LUTNIT have said, using the same brand airseal parts are the best. I don't have experience with the cylinder head you are using, so I can't really help you here.

Before I make the trip over to Home Depot, would they even have the size of o-ring that I'm looking for or should I just go to Canadian Tire?

I meant the o-ring inside the nozzle...it's freaking tiny and I've not seen it at a hardware store...

If you find some let me know where you got them from please.

Last time I had to pick up O-rings just for work, they didn't seem to sell any individual sizes. Usually sold an entire set with different sizes in variety. Thickness may not have differed between them, but I'm not too sure. Keep in mind I was sent out with company money to buy crap for them, so it's not like I was really looking around.

Best bet would be to call ahead this way you're not burning gas for no reason.

Nope, you're totally right. I just went to the Home Depot website and searched for o-rings and they only sold them in kits. Not only that, they don't mention what sizes they come in in the descriptions. I just don't want to waste my time and go over there and can't find what I'm looking for because I'll be taking the bus. I don't own a vehicle at the moment.

Yeah, that's the o-ring that I removed and re-lubed from inside the nozzle. Really tiny, looks like it has an inner diameter of about 5.5mm and a thickness of about 0.80mm.

I found this one place on google, Apple Rubber Products Inc. I'm going to request a sample first before I make any purchases. Also, I don't know what their minimum quantity is but I'll ask them. If I do end up purchasing o-rings from them, would you want to go halves with me?

Try to remove the o-ring and use rubber sealing gasket. Wipe off excess gasket and test air seal. I haven't done this but read a lot years ago from filairsoft.com

What's the difference between Rubber Sealing Gasket and good ol' Silicone Grease? Can I get this Rubber Sealing Gasket from Home Depot or Canadian Tire?

A rubber sealing gasket is essentially a rubber washer, if I remember correctly. I don't know whether or not that would be beneficial, though, since a rubber gasket would be thinner, and if you're having an air seal problem that might not be the remedy you're looking for. I'm not too familiar with innerworkings, though, so it may be something to research upon.

I would like to think they're available at Home Depot. Canadian Tire might have them, and that's a big might. Like, 50 foot high might. If anything, you're best bet for some of those would be a Home Hardware, I find that they are really good for that kind of stuff. However, a lot of airsoft parts are considered "specialty" items by these stores, and then don't carry them, sort of like the .110 clips that attach to your motor. Some people find them in Canadian Tire, I had to go to a specialty electronics store.

Again, call.

Also, the websites for Canadian Tire and Home Depot are piss poor. Don't rely on them. I internet'd Canadian Tire about a hard-cover gun case, and they said they only had the bags. Lo and behold, I call there, and they have hard-cover gun cases on sale for 15 dollars.

Edit: Here's a rubber sealing gasket. Note that it's thin, not a tube-like ring.

swap out cylinder heads and see if you get a good compression test with the nozzle. even if you test it with a stock one, just see what kind of air leak you get manually pushing the piston in the cylinder.

I just swapped out the ARS MASK Cylinder Head with a Prometheus Cylinder Head (same brand as the air seal nozzle) and I'm still getting the same air leak with the nozzle. But without the nozzle, with my finger over the Prometheus cylinder head, it's an air tight seal. Same goes with the ARS MASK cylinder head.

Yes to this! I'm still fairly new to AEG work, but I have definitely found this to be true. When your trying to seal in air, every tiny fraction of a millimeter counts. If you want to solve your issue easily, buy a Modify cylinder set from Airsoftparts.ca. I have used these twice now and the compression is very impressive....nearly perfect. Buy it and be glad you did.

Rubber sealing gasket comes in a tube and you apply it on the groove where you have removed the nozzle's o-ring. Wipe excess gasket and let it dry. While a silicone grease just lubricates and improves the airseal.

After applying, insert cylinder head in the airseal nozzle so it would flush the gasket, then wipe the excess.

So I would then have to get something that has a smaller diameter than the o-ring from my nozzle, right?
