2019 Brake Reservoir O Ring

[TjCj]

Went to go riding yesterday with a buddy . Left his house and he had no brakes '19 Summit X 850 , so we turned around and filled his reservoir . Turns out it's leaking at the O- ring underneath. SkiDoo parts guys says they don't sell the o-ring separately, have to buy a new $80 reservoir, which they are out of indefinitely . And you can't just run to Hardware store and buy 1 because they won't hold up the brake fluid . Is that true , and if so anyone have a line on where to get a $2 O-ring , instead of spending $80 ?
Thanks

I would just buy, or buy a munster one, and you could also buy the hardwear store o-ring but have a back up if that goes south, 80 bucks is cheap to get you out riding again.

MacMaster-Carr or your favorite auto parts store should have chemical resistant 0-ring kits, or be able to make one for you from roll stock.
