A galvanized steel shell holds a molded intumescent insert that expands in fire to close melting pipe.

Frequently Asked Questions
Where do firestop crews use SpecSeal LCC400 on a job?
SpecSeal LCC400 Firestop Collar is the 4 in factory collar for plastic pipe through fire-rated walls and floors. Crews set it on PVC, CPVC, ABS, HDPE, and other published plastics in concrete floors, concrete over steel deck, concrete and block walls, gypsum board walls, and wood floor assemblies. Vented DWV and closed conduit or water-supply pipe are both in the published application range.
When does the LCC400 insert start to expand, and how far can it grow?
The molded insert begins to expand at 320 F (160 C) and continues expanding up to 1,000 F (538 C). Free expansion is 32x to 64x original volume, forming a dense, highly insulative char that closes the opening as the plastic pipe melts. Physical properties on the LCC PDS publish that 32x to 64x range.
What closed and vented pipe services does this 4 in collar protect?
The LCC family is used on vented DWV and on closed installations such as electrical conduit and water supply. Pipe materials on the PDS include PVC, ccPVC, CPVC, RNC, PP, FRPP, FRP, HDPE, PE, PVDF, ABS, and ccABS. Always match the published design to the pipe type and the wall or floor rating.
How long can unused LCC400 collars stay in the van?
The LCC PDS publishes shelf life as no limit when the collar is kept as supplied. Galvanized shell and molded insert do not rely on a water-based paste that can dry out in the carton. Inspect the device before install and replace any collar that shows subsequent damage, using SpecSeal products per the original approved design.
Which LCC size should a crew pick for 4 in trade pipe?
Choose SpecSeal LCC400 when the plastic pipe is 4 in (102 mm) trade size. The live sister collar is 3 in SpecSeal LCC300. 1-1/2 in LCC150 and 2 in LCC200 appear on the PDS and are not currently live on Indcon. Do not substitute a smaller collar on a larger pipe.
What published design should crews follow with sealant around LCC400?
Use the UL system or STI System Search design that names this collar for that pipe and assembly. Some designs call for an intumescent sealant at the annulus; others treat the factory collar as the device. Ratings in the PDS go up to two hours for common masonry and common plastic pipes. Do not guess a system number on site.
