    So after all my "fancy" designing I realize there was a MUCH simpler way to go about this. There's an ABS adapter that might work better, depending on the room available in the open space inside the side pods. It's a 3.5" to 2" (about 89mm to 51mm) adapter. By printing a ring to bridge the gap between the outer dimensions of the vent (79mm), and the inner dimensions of the 3.5" adapter, it would be a nice tight friction fit. I might try printing one up tonight. I uploaded the new adapter piece to the Thingverse site under my ID. Stay tuned for updates.
    Thanks,

    Nic.

    Twice now, I've purchased these, and they're too small for the heater box openings. So either I have aftermarket heater boxes or I don't get how these are supposed to be used.

    Thoughts or suggestions?
    Thanks,

    Took me a few to get the context...
    Okay, if I'm getting this right, you're trying to mate your heater box to your hoses but its the wrong size, so, are you having difficulties getting the correct reducer or adapter?
    Because, while you're having difficulties getting a specific car part to mate up, have you considered other options, like swiming pool pipe adapters, reducers and so on for example.
    I'm pretty sure you're already doing this, but think out of the box, don't lock yourself into one mindset on where the parts come from and you just might find what you need.

    Hi Nic, Please don't buy for a third time or we'll start to worry ;-)

    Hope this helps:

    What I'm referring to is everything from this point to the body. But perhaps I'm overthinking it. How hot/warm do the heater boxes get? Hot enough to melt ABS?

    The heat exchangers on my old bug got VERY hot since they were effectively part of the exhaust, so you probably want something that'll cope with the equivalent heat of an exhaust pipe.
    Mine was never standard, so I didn't have many of the standard fittings and while the pipes in it were high temperature aluminium flex duct, I can't say what they were originally...
    Maybe something like this would work for you?

    Or something along the lines of this search?

    {EDIT}

    I did a little digging and it seems I was wrong and was astounded to find they used plastic/rubber connectors to connect the heat exchanger to the ducts:

    This link shows a fair selection of ribbed connector tubes, rubber joiners and more...

    Though I'm still dubious about connecting a piece of plastic to a hot exhaust pipe...

    Thanks for that info Gaisa. I did some measuring of 'stuff' and here's what I found, for what it's worth.

    The heater box exit has a 60mm outer diameter. About 57mm inner diameter.


    A 2" ABS pipe fitting fits over that 60mm exit quite well (now I know the heater box would end up melting the ABS, so that's out)


    The 2 pieces that I mention I bought twice, fit really nicely inside of the Craftsman flexible tubing.


    And also fits nicely inside the 2" ABS pipefittings



    With the adapter I printed to accept a 2"ABS pipe fitting, I'm not looking at this (taped together for now, and those black lines are my hydraulic lines).
    The Y adapter will got the upper vents that feed the windshield demisters.


    Here you can see the ABS fitting to the right, and the demister inlet at the top. I'm working on something to connect another ABS elbow fitting to the top inlet, and am thinking the flexible hose to connect the two.




    So, now I'll look for some 60mm aluminum or other heat resistant car ducting to work into the design.

    Thats fair, but I guess you beat me to it as I learned a little more, the following link (http://www.autocrafteng.co.uk/shop/b...-2-63-71_3166/ ) shows the flex duct that is apparently used, and it will flex with the engine movement where an aluminium duct will harden over time and break up, it seems to deal with the melting issue by using the rubber gasket (http://www.autocrafteng.co.uk/shop/s...-2-62-79_3167/ ) to break the heat transfer and melting problem.

    (Oh, I edited my original post as I realised that while I was right about the exhaust melting plastic issue, they broke that connection with the gasket which I'm commenting about in this post)

    As far as I can tell, the heat issue is in the transfer of heat from the METAL of the exhaust/exchanger to the body of the duct, thats why the gasket breaks that problem, as for the rest of your ducting, I think it'll cope with the heated air well enough...

    To be honest though, I was expecting an old school equivalent of this:

    A long time ago, I was driving back from a Fair in my 1302-S beetle. My friend had won an LP record at the Fair (yeah, it was that long ago) and put it in the passengers footwell. Anyway, on the way home (a 60min drive on the Motorway/Freeway) the Beetle heating system melted the LP record - so it can get very hot on a long fast road.

    You are both right to tread carefully regarding connections from the heat Exchangers/Boxes into the car, because of these potential high temperatures. However I'm concerned about the pipe running inside the sills as well.

    In the UK (and I assume the US) domestic pipe can be ABS, PVC or Polypropylene, choose the one with the best heat retardant properties (apologies if you've already done that). One of the links in the above thread is for flexible heater hose with a 'tin foil' internal lining, could that be used inside your existing pipe to give some extra heat protection?
