When passing steel, cast iron, copper or plastic pipes through walls, ceilings
or floors, PSI sleeves are the best method of hydrostatic sealing.

Wherever the Link-Seal® modular seal or Compakt Seals are used to seal the annular space between the carrier pipe and the wall duct, the PSI sleeve is also an essential item.
