Abstract
A manway gasket includes a seal body having an annular plate shape defining an inner diameter concentrically disposed within an outer diameter and a thickness bounded by an upper surface opposite a lower surface. The upper surface is configured to abut and/or be adjacent to an inside surface of a dovetail groove of a manway cover. A circumferential channel is formed in the seal body, the circumferential channel open to and starting from the outer diameter and extending inwards towards the inner diameter while not penetrating through the inner diameter. An O-ring is disposed within the circumferential channel. An annularly shaped locking ring is at least partially disposed within the circumferential channel adjacent the O-ring. The O-ring is fully enclosed within the circumferential channel by the seal body and the locking ring. No adhesive, glues or bonding agents are used in the manway gasket.
