As a heat break, its low conductivity creates a sharp thermal boundary that reduces heat creep into the cold zone, helping prevent filament jams and enabling reliable high-temperature printing with materials like ABS, ASA, Nylon, and PC.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this heat break include a PTFE\/Teflon tube?\u003c\/h4\u003e\n\u003cp\u003eA: No PTFE tube is included inside the bore. However, the 4.2mm tail drill hole is designed to accept an optional 4×2mm PTFE tube at the entry point to reduce friction and inner-wall wear during the filament feeding process if desired.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this heat break work with both 1.75mm and 3.00mm filament?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, this heat break is available for both 1.75mm and 3.00mm filament diameters.
