@tubetime this "conical" groove means the o-ring will expand in it under pressure and prevent it from being watertight enough, or is it just me?
Not only this requires a tool entry hole that adds a point of failure, but a simpler straight groove might have been much better for watertightness, right?
Who designed that? Looks like they didnt even do basic homework on this.
@f4grx no this is the standard way to capture an O-ring. a square groove would allow it to fall out. the trick is to use the right parameters so it compresses the correct amount. and i'm pretty sure there's a clever trick to eke the tool into place without leaving a plunge hole.
