Knapp’s patented Ultra-Seal Pig is the best sealing pig on the market.
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 Pig with EZ-Launch Nose is designed for use in pipelines with vertical launchers or changes in pipe diameter due to varying wall thicknesses
Pig Tracking: Adapters: Ultra-Seal Pigs are available with optional pig-tracking transmitter adapters to accommodate acoustic “pingers”, electromagnetic transmitters, high-strength magnets and nuclear tracking sources.
By-Pass Ports: Ports running the length of the body.
Handling straps: Nylon handling straps or ropes embedded in the body of the pig.
