Abstract
A seal assembly for use in a tubular includes a mandrel, a compressible seal member disposed around the mandrel, a first piston assembly in contact with a first end of the seal member, and a second piston assembly in contact with a second end of the seal member. The first piston assembly includes a piston head, and a piston extension sealing member integrally formed with the piston head, and extending at least partially between the mandrel and the compressible seal member. The compressible seal member forms a seal with the tubular when at least one of the piston assemblies is urged toward the compressible seal member.
