Find out more about materials in this offer here:

RED-X nozzle is designed for composite materials as our Nylon CF15 Carbon, CPE CF112 Carbon, and Nylon AF80 Aramid. The nozzle resists all common 3D-printing materials up to a hot end temperature of 450 °C.

Features:

Extreme resistance to wear
Contains artificial ruby with a Mohs Hardness of 9.0
Tested for all our materials

Note:

Do not drop the RED-X and avoid pressure.
Do not use temperatures higher than 450°C.
Avoid clogging the nozzle due to permanent high temperatures or temperature resistant particles in special filaments.
Before printing, make sure the used filament exceeded the glass transition temperature.

Setting up:

For safety reasons, always wear safety gloves while assemble or dissemble the nozzle or handling with other hot parts of your 3D-Printer.
Mandatory tools: torque wrench with 7 mm hexagonal socket, 16 mm wrench or adjustable wrench, safety gloves

To remove the old nozzle, heat up your hot end up to 240 °C and loosen the nozzle with a suitable wrench. Additionally, use a 16 mm or adjustable wrench to secure the Heat Block in place during the process. Cooldown the hot end and completely remove the nozzle.
Take your RED-X nozzle and screw it in by hand. Make sure there is a proper connection between heat break and the nozzle. Again, heat up your hot end and tighten the nozzle with a torque wrench (7 mm hexagonal socket) with a torque of 1 ~ 1.5 Nm.
Also, consider information as specified by the manufacturer of your 3D-Printer.
