Create O-ring Groove on Radial surface
Create O-ring Groove on Radial surface
(OP)
Does anyone have any suggestions on how to create O-ring groove on a radial surface. (face seal on radial surface) I have tried to use Cut sweep/loft with no luck. I have also used the wrap feature but this creates a groove with tapered walls.

What I would do is offset the outer surface of the shaft the O-ring depth before you cut the hole in the shaft. Then cut up to surface the diameter of the O-ring.
I hope that makes sense!
I’d be happy to send you an example if you like.

Got it. I'm doing something similar at this time.
My case is easier, since the face is spherical, resulting in a planar O-ring groove.
Is your part molded or machined? A machined part will probably be easier, since you won't need to incorporate draft.
For a machined part, I would try wrapping a curve for the groove centerline or edge. Then use the wrapped curve as a guide for a sweep cut. The section for the sweep should be on a datum plane made especially for the purpose using normal to curve, constrained normal to the guide. The section sketch should be constrained w.r.t. the guide curve with a pierce constraint.
For a molded part, start like one would for a machined part, then add features to provide draft as needed. there is a way to do this with a single sweep, but it is too much to explain here.
