SRAM Force Lever Reservoir O-Ring

Is this the correct part for replacement o-rings of the SRAM Force E1 lever bleed port screw?

Seems you get 20 o-rings AND the associated T10 Torx screw. I’d settle for just the o-ring but I suppose for $15 here in the US it’s not too bad to also replace that screw. For a home mechanic a single pack of 20 should last me a decade. (Or less spread across multiple bikes.)

Hardware store and I find one “O” ring for EPDM (DOT) or Nitrile (Buna-N) for mineral oil.

The bleed kit may come with extra o-rings, could get a bleed kit or ask a friendly shop if you can buy their spare o-ring. At some point the bleed kit hoses get hard and more difficult to use, usually before needing that extra o-ring.
