Abstract
A hollow annular seal for sealing two concentric components in a subsea environment is disclosed. The hollow annular seal is constructed from an elastomeric material with a hollow core. The hollow annular seal also includes a plurality of apertures to allow fluid to flow through the apertures and into the hollow core to prevent collapse of the fluid filled, hollow annular seal.
