A Modular Seal assembly, as manufactured by Pipeline Seal & Insulator (PSI) correctly installed at each end of the pipeline casings, at highway or railroad crossings, provides positive, hydrostatic protection against the entry of foreign materials and eliminates corrosion and ice damage in the annular space between the carrier pipe and the casing.

End Seal assemblies, available in various configurations and materials are effectively used to seal the end of the casing.

Link-Seal® Modular Seals are designed for use as a permanent seal, produced with a special compound to resist damage from aging, ozone, sunlight, water and a wide range of chemicals. The Link-Seal® mechanical seals may be used to seal annular spaces ranging from 0.5” to 4” and for pipe size from 0.58” to 72.0” in diameter. Applications include concrete, cast iron, steel, copper, plastic pipe or electrical and telecommunication cable, resisting temperatures from as low as –60° F (-51° C) to as high as +400° F (204° C)
