PVC duct flex hose adapters are specialized fittings used to securely connect flexible ducting hoses to rigid PVC ductwork pipes. Flex hose adapters are designed for applications where direct, rigid connections are impractical or impossible due to space constraints or the need for movement. By allowing for the attachment of flex hoses to fixed ductwork, these adapters work to accommodate the vibrations, expansions, contractions, and movements that may occur within ventilation systems. This in turn helps to prevent leaks, maintain duct line integrity, and keep the system working.
Flex hose adapters are manufactured from professional grade polyvinyl chloride (PVC) for the durability, chemical resistance, and service strength to withstand a wide range of work conditions. They are made from Type 1 Grade 1 Cell Class 12454-B PVC and meet ASTM D1784 standards for high quality, consistent performance across various ventilation applications involving air, fumes, vapors, exhaust, dust, and/or particulates. PVC duct flex hose adapter sizes range from 2″ x 16″ in diameter with either hose spigot x belled socket or hose spigot x duct spigot connection options.
