Are you looking a pressure connection like a flange or a structural connection?

 

[racookpe1978]

Internal pressure or external pressure?

Manhole (or handhole) type curved (oval, elliptical) cover into a PV or pipeline?

Or a flat (rectangular) plate with an outlet pipe or fitting on the non-circular plate on the side fitting or enclosure on a PV or pressurized pipeline?
