Petersen Products’ Multi-Flex Annular Seals slip over the end of a pipe, creating a seal between the inner bypass pipe and the outer main pipeline. Annular Seals are possible for almost any size, pressure, chemical or temperature requirement. The seals are very flexible, easy to install, and offer many inflation connection options. The seals are ideal for bypassing a pipeline during repairs on a variety of small to large temporary pipeline connections. 800-926-1926; www.petersenproducts.com.
