HOUSTON, TX – Rectorseal®, a leading manufacturer of firestop products and mechanical devices for professional contractors, announces the new Intumescent Sleeve to our full line of firestopping products. An ideal approach for firestopping the uneven contours of a concrete fluted deck assembly.

The Intumescent Sleeve is a firestop seal for PVC, cc-PVC, CPVC, FRPP, PP and ABS pipe and rigid non-metallic conduit installations. Easily installed without modifications, steel bolts or fasteners. The Intumescent sleeve easily wraps around pipes and eliminates the need for collars or wrap strips – firestops both sides of the wall.

RectorSeal® Intumescent Sleeve is available in 2 sizes which fit (2′, 3, & 4″) and (6″ & 8″) plastic pipe. The Intumescent Sleeves saves on labor cost with no measurement of material, can be easily removed and replace – great for retrofit. The Intumescent Sleeves are moldable and easily conform to contours of the pipes simplifying installation of pipes going through wall and floors at an angle.

RectorSeal® Intumescent Sleeves is now available through Rectorseal®’s nationwide network of distributors. For more information, contact RectorSeal Customer Service at 1-800-231-3345 or visit the company on the web at
