NUCO TYPE-SSC INTUMESCENT COLLAR SYSTEM - 4IN

Self-Seal® Type-SSC is a prefabricated firestop collar featuring a galvanized metal housing with an intumescent silicone ring, designed to seal combustible pipe penetrations in fire-rated walls and floors. When exposed to temperatures above 150°C (300°F), the silicone rapidly expands, forming a patented graphite-reinforced char to fill voids created by melting pipes. Available for 1½" to 4" trade-sized pipes (38–102 mm), its low-profile design accommodates tight spaces while maintaining fire integrity under positive pressure conditions.

Key Features & Applications:
✔ Prefabricated solution – Galvanized collar with molded intumescent silicone ring
✔ Combustible pipe protection – For PVC, ABS, CPVC, PEX, IPEX XFR®/Aquarise®, and FRPP pipes
✔ Space-efficient – Low-profile design fits constrained angles
✔ Tested performance – Validated under fire conditions with positive pressure simulation
✔ Versatile compatibility – Works with solid/vented/cellular-core plastic pipes and sprinkler systems

Ideal for rapid, code-compliant installation in commercial and industrial firestopping applications.
