Replacement Thermal Break for Micro Swiss All Metal Hotend Kit for CR-10 / Ender Printers

Picked up an extra along with a hot end block. Be careful not to cross thread the latter. Screw nozzle in by hand, then heat it up and torque it. Save problems later.

I’ve ordered spares several times, turnaround on orders is always quick and efficient, as is their technical support. Products are of high quality and reliable.

MS ALWAYS answer the phone and questions fast! Package was misplaced USPS said delivered but we couldn't find it so I called and MS and they sent a replacement FAST. Couldn't be happier with the V2 Kit I purchased for the NG. QUALITY ENGINEERING and prints never looked better!

Amazing Customer Service

Make sure the heat block is at extruding temp when you tighten the heat break to the nozzle. Do not tighten anything to the heat block, it is the junction between the heat break and nozzle that is critical, and must be tightened when the heat block is at operating temperature. The first time I tightened them at room temp and molten PETG leaked out, smothered the heat block and nozzle, and ultimately clogged. Also, reduce the retraction to 1mm or less.

Works great after correct installation.
