Blowout Preventers


Rod-and-piston seals inside blowout preventers were deforming and extruding under high pressure and jeopardizing safety standards.


System Seals upgraded the seal material to HNBR and added two thermal plastic backup rings to prevent extrusion.


Tests revealed that the new System Seals design performed flawlessly – three times longer than the manufacturer specified. All existing BOP seals have been replaced.
