Flexible Duct Wire Core Only
Fastflex's flexible duct wire core is the structural backbone of any flexible duct assembly — the helical wire spiral that gives flexible duct its shape, strength, and crush resistance. Whether you're replacing a damaged wire core, building a custom flexible duct assembly on site, or stocking up for a large installation, this is the component that keeps your flexible duct performing as it should.
Maintains Duct Shape & Structural Integrity The helical wire core runs through the inner liner of flexible duct, holding it open against the negative pressure of the ducted system and preventing collapse or kinking. Without a sound wire core, flexible duct restricts airflow, reduces system efficiency, and can fail prematurely — making this an essential component for any quality ducted installation.
Sold in Practical 6 Metre Lengths Available by diameter size in 6 metre lengths — easy to handle, transport, and store on the job. Order the diameter to match your existing flexible duct and you're ready to go.
