Running cable run in a hostile environment is no easy task. Sometimes conduit, no matter how rigid, is simply not enough protection for your cables. Water, gas, and even rodents can get into the conduit and damage your wires if the conduit is not properly sealed. FST Foam Duct Sealant plays a key role in such applications by completely sealing conduit, equipping it to handle events that most open-cell canned foams can't protect against.
