Ultra-Seal Lite Pipeline Pigs

Custom Built for Purpose

The Ultra-Seal Lite Pig is a hand-crafted, custom-built pig. The specific design and materials for each pig are determined by the configuration of the pipeline and operational requirements of the pig. Typically the Ultra-Seal Lite Pig is used for dewatering and fluid control in multi-dimensional pipelines.
