Holdrite HFPESC3 Fire Stop Extension Sleeve 3 Inch Pipe

Product Description

The HOLDRITE HFPESC3 is a cast-in-place firestop extension sleeve designed for use with 3-inch fire stop sleeves serving metal or plastic pipe. Part of the HydroFlame Pro Series, this sleeve provides a combined water seal, smoke barrier, and fire barrier in a single assembly. The patented telescoping design eliminates field cutting, and integrated locator whiskers help technicians locate buried sleeves after a concrete pour. The threaded safety cap allows non-destructive removal and meets OSHA hole cover requirements. This product is UL listed for water, smoke, and firestop performance and is installed by licensed plumbers and fire protection contractors.

The HFPESC3 is used in cast-in-place concrete floor and wall assemblies where 3-inch metal or plastic pipe penetrations require firestop protection. The 4-inch hollow sleeve accommodates the penetrating pipe and integrates directly with compatible HydroFlame Pro Series firestop sleeve assemblies. It is suited for multifamily residential, commercial, and mixed-use construction where penetration firestopping must meet UL system requirements. Water dam and water module accessories are available separately for applications with added water-tight requirements.
