Item#: LCC150


LCC Intumescent Firestop Collar (LCC150)

The economical solution for firestopping common plastic pipe that doesn’t compromise safety or performance.

The SpecSeal® Series LCC Collar is a factory-manufactured device designed to protect plastic pipes penetrating fire-rated walls and floors. Utilizing a heavy gauge galvanized metal collar to house a molded intumescent insert, the SpecSeal Series LCC150 Firestop Collar is specifically sized to fit 1-1/2˝ trade sized pipes. When exposed to temperatures in excess of 320°F (160°C), the SpecSeal Series LCC Collar’s molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Its free expansion ranges from 32-64 times original (pre-expanded) volume. Expansion continues up to 1,000°F (538°C).

Common Applications:
- Protects a variety of plastic pipes – PVC, PVC Foam Core (ccPVC), CPVC, ABS, ABS Foam Core (ccABS), FRPP, PP, PVDF and HDPE pipes
- Vented (DWV) and closed (electrical conduit and water supply) installations
