- Keeps a small profile so crews can set the collar in tight wall and floor cavities.
- Stays water resistant in the opening because the insert has no water-soluble expansion ingredients.

SpecSeal LCC300 Firestop Collar - 3 In
SpecSeal LCC300 is the 3 in factory firestop collar for plastic pipe through fire-rated walls and floors. A galvanized steel shell holds a molded intumescent insert that expands in fire to close melting pipe. The collar is sized for PVC, CPVC, ABS, HDPE, and other published plastics in concrete, gypsum, and wood assemblies, including tight spaces where a small-profile collar is easier than wrap strip.

Frequently Asked Questions
What plastic pipe jobs is SpecSeal LCC300 built for?
SpecSeal LCC300 Firestop Collar is a factory collar for 3 in trade plastic pipe through fire-rated walls and floors. Typical work includes PVC, CPVC, ABS, and HDPE DWV plus closed pipe such as electrical conduit and water supply. The collar is made for concrete floors, concrete over steel deck, concrete and block walls, gypsum board walls, and wood floor assemblies.
How does the LCC300 insert close a burning plastic pipe?
When heat exceeds 320 F (160 C), the molded intumescent insert begins to expand rapidly into a dense, highly insulative char. Free expansion ranges from 32x to 64x the original volume, and expansion continues up to 1,000 F (538 C). That char closes the opening as the plastic pipe melts.
Which plastics and services does the 3 in LCC collar cover?
The LCC PDS names PVC, PVC foam core (ccPVC), CPVC, RNC, PP, FRPP, FRP, HDPE, PE, PVDF, ABS, and ABS foam core (ccABS). Services include vented DWV and closed runs such as electrical conduit and water supply. Confirm the published design for the exact pipe and assembly on the job.
What constructions can crews install LCC300 through?
Suitable constructions include concrete floors, concrete over steel deck, concrete walls, concrete block walls, gypsum board walls, and wood floor assemblies. Systems have been tested for common masonry construction and common plastic pipes with ratings up to two hours. Follow the published UL system for the wall or floor on site.
Which other LCC collar size can crews order with this 3 in model?
Indcon currently stocks the 4 in SpecSeal LCC400 as the sister collar. The LCC PDS also shows 1-1/2 in (LCC150) and 2 in (LCC200) collars; those sizes are not currently live on Indcon. Match trade size to the pipe, not to the opening after wrap.
What should crews follow when pairing LCC300 with sealant or wrap?
Follow the published firestop design for that assembly. The collar is a factory device; some designs still call for an intumescent sealant or wrap strip at the annulus or on larger plastic pipe. Do not invent a system number. Use STI System Search or UL Product iQ for the exact design.
