Nozzle and hotend buying guides
Compare the part that fits, the opening you need and the pieces you will use.
Find the nozzle that fits your printer and hotend →Start with the complete printer model and the hotend that is on it now. If you bought the printer used or fitted an upgrade, check the installed assembly against the maker’s replacement diagram. Save that match before comparing nozzle openings or materials.Choose between a nozzle and a complete hotend →Decide what you intend to replace before comparing prices. A nozzle for an installed system can cover a diameter change. A complete assembly makes sense when the parts you need to replace are included and the electrical connections match the exact machine.Choose a Prusa Nextruder nozzle or a V6 adapter →If you already own suitable V6 nozzles, check whether Prusa’s adapter supports your specific printer. If you want a direct replacement for a Nextruder, begin with the native Prusa Nozzle family and compare the size, material, and printer profile you plan to use.Choose a nozzle for an installed E3D Revo hotend →Confirm that your machine already has a supported Revo system. Then choose a nozzle for the jobs you actually repeat, such as a finer opening for small features or a standard size that matches a profile you already use.Check your Neptune 4 toolhead version before ordering →Start by identifying whether your printer is a Neptune 4, 4 Pro, 4 Plus, or 4 Max. Then check the version named in the nozzle listing. On ELEGOO’s multi-size brass kit, the cable revision changes the fit for two of those models.Choose the hotend for your Anycubic Kobra model →Kobra is a family name. Use the full model label, including S1, 3, 3 V2, or 2 and its suffix, to get to the appropriate part list. The available openings and materials depend on the exact assembly.How to tell MK8, V6 and Volcano-style nozzles apart →An M6 thread and a 0.4 mm opening can appear on more than one nozzle format. Start with the hotend model, then compare the manufacturer’s drawing. On the specific Micro Swiss parts below, the thread can share a pitch while the threaded sections have different lengths.Find the correct side for a Bambu Lab H2C hotend →Start by choosing the left or right hotend position on your H2C. The two positions use different replacement formats. A common opening such as 0.4 mm can appear in listings for both sides.
