Suppressors Area 419 mount o-ring

[021411]

I shot Area 419 an email about the o-rings but it's the weekend.. I some how ripped mine today in my TBAC mount. Does anyone know if the o-ring is required? I'm guessing if I don't have one installed carbon will get on the taper. I take my can on and off for transport so eventually I'll rip another one down the line. I'll buy an entire pack of them if I know the size and durometer.

I thought it was there to help with retention so the mount stayed on? I have extras that came with all my suppressor adapters did yours not?

I’m on my spare now and have a feeling it’ll eventually rip. Just preparing..

I emailed Area 419 about the o-ring a while back. They told me it was another seal to prevent carbon from getting on the mount.

Thanks. I guess in the big sceme of things it’s not required but more of a preventive measure.

Area 419 never got back with me on the sizing so I did my own digging. If anyone just wants spare o-rings with their 419 setup, you can get some from McMaster-Carr. It's part number 1173N017. The durometer is 50A. This one matches what comes with the mounts. I also bought 70A (1283N28) ones as well. Both work fine. They are high temp at 400 and 450 degF respectively.
Sizing is specific for the mounts I believe. So you'll have to measure if you can't get a hold of 419.
