Pipe Choke and Wrap Systems

Nelson Firestop pipe choke system (PCS™) is a prefabricated device used to seal penetrations and maintain the rating of fire rated floors and walls. The pipe choke is designed for penetrations of non-metallic pipes. When exposed to fire, the material expands to seal voids created from fire exposure on deteriorating penetrating items. The PCS™ consists of a heavy gauge metallic collar filled with a highly intumescent, pliable material.
