An alternative to PTFE (teflon) tape (for hopup units)

I hate teflon tape. It's fiddly and gets greasy and disgusting, gets on your fingers and then proceeds to be a pain to get off.
Thankfully I use an action army hop up unit in my vsr10, however, I am looking into getting an aeg, and since action army hoPup units are expensive, not everyone will want to get one.
However, there might be a solution, you see, I was looking at Novritch's website and I got annoyed because his hopup chamber doesn't seal through being well designed, but because he uses a metal ring to clamp down on the hopup rubber.
Here is the link: https://eu.novritsch.com/product/ssg...ng-front-gen2/
Then I wondered whether this could be used in a normal VSR10 chamber or in an aeg, and couldn't tell, so I decided to ask here.
Could this work in
a) a standard vsr10 hopup chamber and not Novritch's slightly modded one.
b) an aeg (specifically an m4 and one of the rotary hopup chambers)

Teflon tape is the way it is...because of what it is being all thin af lol. You can use Teflon with an aa chamber too. I do on all of mine. The AA chambers can produce an excellent seal but if there’s a chance to better something, I’m in! As far as a ring you can make one from super thin wall brass tubing.

I’m sorry, but what garbage Teflon tape are you using that is greasy and gets on your fingers? I’ve used many brands of tape doing plumbing/fitting at work, and keep going back to the jet-lube tape. I go through about 100 rolls a year of it. It is not greasy or film’y. Heck I’ve used it as floss before when I had something stuck in my teeth and didn’t have a floss roll around.

After you use your gun for some time, the parts get greasy. The grease will get on the PTFE tape and that makes it horrible. Not as bad as if you wrapped it around your cylinder head but still enough to incur my wrath.

I have tried this a few times and I would suggest silicone glue like this http://shop.advanceautoparts.com/p/p...E&gclsrc=aw.ds
I think that my mom had a tube lying around last year and I tried doing an S-hop with it (way too soft and not wear resistant) but I tried sealing a bucking on my VSR of the time and it worked.
Now, I will probably not do it again because I have a habit of collecting different colors and densities of Teflon, but a good tip to know if I am in a situation like so.
Teflon is still the very best with this behind it.

What lube are you using? PTFE tape shouldn't turn into gunk...

Lithium Grease. It doesn't melt the PTFE but it makes it dirty.

If you know a gearhead, get some RTV silicone for gaskets, etc. spread a thin layer of it on the barrel before putting the bucking on making sure you don't get any on the r hop patch (if you're going that way) or that it won't end up in the hop window. slide the bucking onto the barrel and gently massage the rtv evenly wiping of the excess that squeezes out and you're good to go. Let it cure on the bench before inserting it into the hop up unit. Getting the barrel into the hop up will be tight so a drop of silicone oil or dish soap smeared on the outside of it will help squeeze it in there. When done you have a super effective air seal that when held in place by the hop up unit will never leak, budge, or deteriorate....and it's still easy to get apart if you need to.

I think that the RTV glue trick is a bit better for AEG bucking IMO.
VSR/GBB bucking don't really have a as hard a time with airseal as I have found, but there are always exceptions

I've used it on everything...from Strikers to L96's to MP5's and pistols. You can't have too much airseal. It is trickier to pull off than just tape (curing time, temperature, sizing, etc), but the results are there.
