An annular sealing device having a positive stop to prevent over pressurization on the sealing device. The annular sealing device includes a substantially rigid support member having at least one substantially flat outer surface portion. There is a generally round cavity formed in the substantially rigid support member adjacent the at least one substantially flat outer surface. This generally round cavity has a first predetermined diameter and a predetermined depth. A generally round elastomeric sealing member having a predetermined thickness and a second predetermined diameter is disposed in the generally round cavity. Elastomeric sealing member has a substantially flat face engageable with a predetermined surface to be sealed. A stop means is engageable with at least a portion of the substantially flat outer surface portion of the substantially rigid support member for preventing undue penetration of the surface to be sealed into the generally round elastomeric sealing member.
