Foremost Duct LLC: Self-Sealing Spiral Duct
November 28, 2003
The SPIRAmirâ„¢ self-sealing spiral duct system allows round duct and fittings to be joined without the use of duct tape or a sealant, the manufacturer states. According to the company, this system results in lower field installation costs. It can be used with the company's polyvinyl-coated ductwork (PCD), galvanized steel, or aluminum duct systems. It features a factory-installed O-ring with a temperature range of -20 degrees to 210 degrees F. If the O-ring is damaged, it can be replaced with a new O-ring.
