The rubber layer on the ram is reinforced at the sealing areas by forming ribs on the ram core. The ribs function to resist extrusion of the rubber layer when the blowout preventer is subjected to high pressure from the well.

La couche de caoutchouc sur la mâchoire d'obturateur est renforcée aux points de scellement en formant des nervures sur l'âme de la mâchoire d'obturateur. Les nervures permettent à la bande de caoutchouc de résister à l'extrusion lorsque le bloc obturateur de puits est soumis à des pressions élevées dans le puits.
