Frequently asked questions
Do I need a PTFE tube with it?
This product is sold without a PTFE (Teflon) tube. If your build uses a PTFE liner, source one separately that matches the bore of the throat pipe.
Which printers is it compatible with?
It is listed for CR-10S and Ender-3/3S printers with an MK8-type extruder. Confirm that your extruder and hotend use the same throat type before fitting, since throat designs are not always interchangeable.
