Product Overview

An Annular Blowout Preventer is a pressure-control device installed at the top of the BOP stack. It uses a reinforced elastomer packing element that is hydraulically compressed inward to create a pressure-tight seal around tubulars of varying diameters or across an open bore.

Unlike ram-type BOPs, an annular preventer can seal around irregular shapes and multiple pipe sizes without changing components, making it one of the most versatile well control devices available.
