Lansas’ built-to-order Well-Packers are great for sampling above, below or between units, and allow for well isolation. Our Well-Packers can be made in sizes from 1 to 24 inches in Fixed-End or Slip-Fit styles to handle pressures up to 200 psi. If you need larger sizes or have special requirements, call 800-452-4902 or go to and complete our Well-Packer Build Sheet to see what Lansas can do for you today! Email:
