Heater Ducting Question

[panzerjunky]

Good evening Fellas
Does anyone know where to get the black heater ducting with the silver stripe running around it or what is a good replacement?
Thanks Jerry

Jerry, NAPA has 4 inch heater ducting . I think it comes in 6 foot lengths.

you can also buy pretty much the same stuff from McMaster Carr (industrial supply house). They have a lot of different kinds to sift through, but some very nice choices for replacement hose.
