Feature:1. HIGH TEMPERATURE RESISTANT: The Ti alloy at the front end of bimetal heatbreak has good heat insulation, high temperature resistant, wear resistant, and can withstand 450-500 high temperature2. FLUENT AND UNOBSTRUCTED: The CuCrZr at the back end of the hotend bimetal heatbreak has good thermal conductivity, the inner wall is glossy and no burrs, and the feed is fluent and the resistant is reduced3. PREVENT WIRE LEAKAGE: The Ra<0.4 of the bimetal heatbreak throat, the glossy inner wall enhances the fluidity of the silk, makes the extrusion more fluent, the appearance is flat, the connection is tight, and effectively solves the problem of wire leakage4. COMPATIBLE CONSUMABLES: High temperature resistant throat tube is suitable for 1.75mm filament and supports printing PLA, ABS, PETG, TPU, PP, PC and other consumables5. USEFUL AND PRACTICAL: This is a 2 in 1 throat for the Kobra 3 3D printer with combined hot ends, M6 threads, and can be installed for immediate useSpecification:Item Type: Bimetal HeatbreakMaterial: Ti alloy and CuCrZrApplication: For Kobra 3 combined hot endThread: M6Diameter: Approx. 1.75mm / 0.07in.Package List:1 x Throat Tube
