STI Firestop SpecSeal SSC400 Intumescent Firestop Pipe Collars sized to 4" plastic pipes. The SSC400 Firestop Pipe Collars consist of a restraining collar with a factory applied intumescent to ensure that the right amount of material is applied every time. Under fire exposure, the SSC400 Firestop Collar quickly expands and collapses combustible piping to form a dense char, and resists any passage of flames, fire, or smoke.

SpecSeal SSC400 Fire Block Pipe Collars are suitable for use in all common constructions including concrete floors, concrete over steel deck, concrete walls, concrete block walls, gypsum board walls, as well as wood floor assemblies.
