Specification for flexible duct

Specification for flexible duct

Specification for flexible duct

(OP)
I need a 2 ft length of 2.5 inch ID duct for an aerospace low pressure air purge application, probably PTFE but other non-flammables could also work. I can find several mfg products that would suffice, but they all go by a trade name. Is there a specification that covers this type of flex duct that I can use for parts list material callout?

RE: Specification for flexible duct

I believe that you are looking for Scat or Sceet ducting.

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

yes that kind of product would work, but unfortunately have to call out a particular supplier and their product name.
