Hager 729S Intumescent Fire Seal – Category G Edge Sealing System

The Hager 729S Intumescent Fire Seal is a high-performance life-safety solution designed to provide a critical barrier against fire, heat, and smoke. Engineered for versatility and reliability, this Category G Edge Sealing System is essential for meeting rigorous building codes and fire-rated door requirements. Constructed from a flexible graphite core encapsulated in a durable PVC protective coating, the 729S remains dormant under normal conditions but expands rapidly when exposed to extreme heat, effectively sealing the gap between the door and the frame.

High-Expansion Fire Protection

The core of the Hager 729S is its advanced intumescent graphite material. In the event of a fire, once temperatures reach the activation point, the material undergoes a chemical reaction resulting in a 7:1 expansion rate. This dense, insulating char fills the voids around the door perimeter, preventing the passage of flames and toxic gases.

• Durable PVC Coating: The top and sides are covered in a flexible PVC layer, protecting the intumescent core from moisture, humidity, and general wear while allowing for easy cleaning.
• Temperature Versatility: The 729S is designed to remain flexible in environments ranging from -30°F to 140°F, ensuring it won’t crack in cold storage or degrade in high-heat mechanical rooms.
  
• Adhesive Backed Convenience: Supplied with a high-strength adhesive backing for rapid installation. Note: The adhesive has an 18-month shelf life, ensuring maximum bond strength when rotated properly in stock.
  
• Chemical Resistance: The PVC jacket resists most acids, strong alkalis, and salts, making it suitable for industrial and laboratory environments.
