BIOSTOP® Intumescent Sleeve is a firestop seal for PVC, CC-PVC, CPVC, FRPP, PP, ABS and PVDF pipe and rigid non-metallic conduit installations. Easily installed without modifications, steel bolts or fasteners, the Intumescent Sleeve is an ideal approach for firestopping combustible pipes penetrating the uneven contours of a concrete fluted deck assembly. It eliminates the need for collars or wrap strips and is great for use on pipes that penetrate nwalls at less than a 90º angle. It also eliminates the need to firestop on both sides of a penetration. The Intumescent Sleeve easily wraps around pipes and is manufactured from a durable galvanized steel outer shell that is lined with a highly intumescent material. The Sleeve is fastened with either fiberglass tape, pop rivets or hose clamps around the pipe. When used with BIOSTOP® 500+ or 150+ Sealant, it produces an immediate smoke seal
