Best expansion pipe o-rings?

<< < (2/3) > >>

Foxx4Beaver:
The O-rings don't just act as a means to seal up the connection...they also help prevent rapid wear and tear on the inside of the exhaust flange on the cylinder.

I use Loctite 5920 along with the O-rings...it's pretty brutal stuff, but I've had red RTV start leaking a few times over the years.

68Fastback:
I use OEM with Red RTV and a new crush washer and change as needed.

Hawkeye58:
I have found great results from a farm and Ranch type hardware store here in Vegas, with the o rings sold there. If you are fortunate to have a store such as this near by they have lots of different diameters and thicknesses. I matched up the FMF ones and bingo! .35 cents a piece. Those along with your favorite RTV and you are golden.
I am curious as to the longest any of us riders have gotten a set to last?

I'll replace mine once a year, even if they don't appear bad.

I am at a month now after a new FMF Pipe install.
