Specified Technologies Inc. has introduced a one-piece intumescent gasket specifically designed for sealing closet flanges. SpecSeal® Closet Flange Firestop Gasket installs quickly and easily from the top and expands rapidly when exposed to heat and provides code compliant firestop protection for toilet flange assemblies with plastic and metal pipes. Unlike caulk which when installed from above often interferes with flange fit, or below floor installations which require costly lifts, the SpecSeal Closet Flange is a code compliant, ready-to-use firestop solution that requires no tools and no clean up, saving both time and money.
The one-piece, molded rubber intumescent pad installs beneath a 3” or 4” closet flange to effectively firestop the opening. The die cut rubber gasket is perforated to accommodate various outer diameters of toilet flanges in 1 and 2 hour rated floors. L-ratings are also provided for excellent smoke leakage performance.
SpecSeal Closet Flange firestop gasket meets ASTM E814 (UL1479) and CAN/ULC S115.
