    I just purchased V6 Lite kit, and some Capricorn tubes for the Bowden extruder.

    Question: should I use Capricorn as well for the V6 Lite liner, replacing the supplied PTFE?

    You can, but realize that in doing so the temperature limit is not increased.

    Ok, no temperature increase.

    Just confirming that it can be used as a replacement liner.

    Based on this image (supposing it's correct), what makes you say the temperature limit isn't increased ?

    According to capricorn website, their PTFE melting point is 330C. I probably wouldn't push it that high, but seeing that the actual capricorn tubing goes directly to the nozzle (where previously the low melting temperature PTFE used to be (='liner')), I'd be inclined to think V6 Lite's usable temperature should become higher with Capricorn.

    Melting point is not the same as safe operating temperature.

    No PTFE tube should be used at temperatures exceeding 260C.

    I've just found this: https://www.captubes.com/safety.html

    It seems like the usable temperature should get slightly higher than the maximum of 245 as per e3d website.. But probably not more than some 250-260deg..depending if you have birds in the room

    E3D's specification is conservative at 245C to allow for thermistor inaccuracies/overshoot. Capricorn's specification is... less conservative.
