3" SpecSeal® Fire Collar, Pipe Collar Fire Protection *Sold Individually*
The STI SpecSeal® Series LCC Collar was specifically engineered to protect plastic pipes penetrating fire-rated walls and floors to prevent spreading. The intumescent insert is surrounded by a heavy gauge metal collar to ensure sturdiness and reliability. If temperatures were to exceed 320°F, the insert begins to expand, up to 60x its size, forming a highly insulated, dense fire-block and sealing off burning pipes. This fire collar is also water resistant!
