Model FW Fire Resistant Zipper Seal

A safe and economic system for sealing the annular space between the carrier pipe and casing to keep the space dry and reduce the risk of corrosion.

Model FW Fire Resistant end seals have been developed for applications specified as fire prone areas such as tank farms or pipes passing through firewalls. These seals are excellent for eliminating the possibility of foreign material entering the opening between carrier and casing pipes. They are ordered to customer-supplied specifications so they may be used for any size casing/carrier differential.
