Pyroplex® Pipe Collar 4 hr – O/D 55mm

 Pyroplex® Pipe Collar 4 Hour Fire Rated – 55mm Outside Diameter

The Pyroplex® Pipe Collar 4 Hour (55mm O/D) is a high-performance fire-stopping solution designed to reinstate the fire resistance of compartment walls and floors where plastic flammable pipes penetrate fire-rated elements. Ideal for soil, waste and drainage services, this collar provides up to 240 minutes of fire resistance, helping to maintain building integrity and compliance.

Engineered for ease of installation, the collar features a tab closing device that allows it to be quickly fixed around the pipe and either rotated or slid into position. Once exposed to fire, the advanced intumescent material expands rapidly, sealing the opening as the pipe softens or melts, preventing the spread of fire and smoke.
