Zerust/Excor ICT Pipe Strips are a strip of inline vapor corrosion inhibitor (VCI) emitter capsules for protecting the inside of larger pipe and tube during storage and shipping. The strip is fed into the bore and the pipe ends sealed; the capsules emit invisible, odorless, non-toxic VCI molecules that settle onto the interior metal surface and dissipate on opening. Protects ferrous and non-ferrous pipe and tube up to 24 in diameter for up to 1 year. Each 40 ft (12 m) strip carries 10 capsules on 4 ft centers (525-M-00001) or 16 capsules on 2.5 ft centers (525-M-00002). Zerust part number 525-M-00001.
