ABSTRACT:
Seal for the static or dynamic sealing of joints, machine parts or other components or structures such as may be found in choke, kill, or other auxiliary line strings for marine oil or gas well risers, hydraulic or pneumatic cylinders or other actuators. The seal may have a U-cup or solid geometry profile including a secondary sealing lip on both the inner and outer diameter thereof which functions as a wiper for the exclusion of outside contaminants, such as seawater, from joint sealed.
