The SpecSeal® Series SSC 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 SSC Firestop Collar is specifically sized to fit 1-1/2 in (38 mm), 2 in (51 mm), 3 in (76 mm), and 4 in (102 mm) trade sized pipes. When exposed to temperatures in excess of 320°F (160°C), the SpecSeal® Series SSC Collar’s molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Its free expansion ranges from 32x to 64x original (pre-expanded) volume. Expansion continues up to 1,000°F (538°C). 

SpecSeal® Series SSC Collars are used to protect a variety of plastic pipes including PVC, PVC Foam Core (ccPVC), CPVC, RNC, PP, FRPP, FRP, HDPE, PE, PVDF, ABS, ABS Foam Core (ccABS) and XFR 15-50 PVC in both vented (DWV) and closed (electrical conduit and water supply) installations.
