The standard Ultra-Seal Pig has flat, polyurethane elastomer discs on each end. This is the optimum design for dewatering, batching of dissimilar products, and for fluid removal in pipelines of all sizes and pipe materials. The Ultra-Seal can also altered to include a EZ launch nose for vertical launchers or low flow situations. The Ultra-Seal can be modified to accommodate transmitters, magnets and/or radioactive sources. The Ultra-Seal can also be outfitted with pull straps to make pig removal easier.
