ABSTRACT:
In an assembly of two members that are threadably secured and have opposed radially extending sealing surfaces that may experience forced relative tilting there is provided an elastomeric sealing ring that engages these surfaces and has a radially facing circumferential V-shape groove providing lips that are preloaded between the sealing surfaces but do not touch each other on application of a predetermined securing torque and then on forced relative tilting of the members which tends to unseat the ring at some circumferential location the lips at this location remain preloaded while flexing to maintain sealing while at the diametrically opposite location the lips are forced toward full contact.
