Hi. I have a port on a pressure vessel (14 bar). The port is 2" diameter hole. A flange plate bolts over the port. The fasteners are on a 5" PCD. I need an o-ring to seal the port. Should I select an o-ring size that is close to the port size, i.e. just over 2". Or, should I select an o-ring that is close to the fastener PCD, i.e. just less than 5"?
With the former I will be minimise the surface area that is under pressure. With the latter I'll be ensuring good clamping on the o-ring.
