FEATURES:

This product is mainly composed of a metal shell and a thermal expansion core material, which is sleeved on the wall of the UPVC pipe during installation and fixed on the floor or wall. When a fire occurs, the core material of the firestop ring expands sharply after being heated, and squeezes the plastic pipe wall inward to block the hole in a short time and play a role in preventing the fire from spreading. The product has compact structure, reasonable design, safe and convenient construction.
