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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePatented telescoping design eliminates the need to cut sleeves on the jobsite\u003c\/li\u003e\n\u003cli\u003eIntegrated locator whiskers allow easy sleeve location after concrete pours\u003c\/li\u003e\n\u003cli\u003eThreaded safety cap enables non-destructive removal and satisfies OSHA hole cover requirements\u003c\/li\u003e\n\u003cli\u003eUL listed for water intrusion, smoke, and fire protection in a single assembly\u003c\/li\u003e\n\u003cli\u003eCompatible with water dam and water module accessories for enhanced water-tight performance\u003c\/li\u003e\n\u003cli\u003eDesigned for 3-inch pipe penetrations with a 4-inch hollow sleeve profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch fire stop sleeve assemblies in the HydroFlame Pro Series, accommodating metal or plastic pipe penetrations in cast-in-place concrete construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or fire protection contractors in accordance with the applicable International Fire Code and project-specific UL listed system requirements.
