SpecSeal SSCF34 Closet Flange Gasket

The SpecSeal Closet Flange Firestop Gasket is a one-piece, molded rubber, intumescent pad that installs beneath a 3 in (76 mm) or 4 in (102 mm) closet flange to effectively firestop the opening. The die cut rubber gasket is perforated to delineate removable inserts sized to accommodate various outer diameters of toilet flanges.

Traditional firestopping methods require the firestop material to be applied around the pipe prior to setting the toilet flange, which can be problematic if the firestop material is not recessed a sufficient distance from the top to accommodate the throat of the flange. The alternative is to apply the firestopping from the underside of the floor, necessitating the use of ladders or lifts. SpecSeal Closet Flange Firestop Gaskets solve the problem by providing a labor-friendly method of properly firestopping the opening.

• Seamless fit for fast, easy installation with no tools requiredz
• Installs from the top, saving labor
• No caulk to clean up
• Always ready to use - no shelf life - no caulk tubes to dry out

Applications

• Plastic Pipe
• Metal Pipe

SpecSeal Closet Flange Firestop Gaskets are designed to allow the drain pipe connected to a toilet flange to be properly firestopped without the need for firestop caulk for typical floor assemblies with plastic or metal pipes.
