Abstract
An annular fluid seal for pressurized fluid systems particularly for use with a coupling having interconnectable self-sealing male and female parts. The two-part seal is mounted within an annular gland recess within the male part and includes a relatively rigid primary annular body of synthetic plastic material having an interference fit with the male coupling part poppet valve. The outer diameter of the seal body includes an annular recess receiving an elastomeric O-ring, and the mass of the primary seal body provides maximum strength within the confines of the gland recess to resist deformation due to pressurized fluid to prevent blowout of the seal from its recess.
