ESR exhaust O-rings???

[3wheelrider]

has anyone used the exhaust orings from ESR?Will they last at all? -Im asking because they are black (not orange or red etc.) For what they charge ea. + shipping you would think they were HI-TEMP for sure. Thankfully I didnt buy them -A customer was kind enough to order some for my R as well as his TRX....Also what
size mm is it exactly?

I have them on my ESR 310 kit's ex manifold. They have held up just fine, and I have probably close to 50 hours of ride time on the machine so far

Hello


There are many high temp black o rings, see chart below. Notice o ring at the bottom called parofluor ultra. the have a max temp rating of 650 f , your ex temp should be around 600 f max under load.
