    Default Place to order 4 inch high temp flex ducting ??

    I have been using crappy 4 inch soft metal ducting for my red Dragon pre-heater for years. The other day I borrowed another pilots heater hose. It was the internal wire wrapped type covered with some sort of canvas / fabric type of high temp stuff. We had those in the military long ago.
    I went to the local boat shops, Nappa and Spenards and they had no idea what I was talking about.
    Do you city folks up in Los Anchorage have a place to buy that sort of thing?? Amazon.com only has the orange scat tubing and I am not so sure that is high enough temp.

    Thanks. It is interesting that the working temp is 300 degree for the ducting at AIH. I was thinking it would need to be a lot higher.
    I need to head up to Kenai next week for me Class II medical, so I will see who is less expensive between the two.

    Stoddards has the red stuff, I think it has the highest rating you can get. The black stuff AIH has is lower temp raining.

    Ya, the orange stuff has a temp rating of 550 degrees. The black should be fine though for a red dragon
