Abstract
A ram assembly is provided. In one embodiment, the ram assembly includes a base ram having a tapered profile and a seal coupled to the base ram in a manner that allows the seal to slide relative to the base ram during operation of the ram assembly. In some instances in which the ram assembly is installed in a blowout preventer, the tapered profile of the base ram can facilitate compression of the seal in multiple directions. Additional systems, devices, and methods are also disclosed.
