Genuine E3D Revo nozzles for any Revo hotend, including the Revo Voron coldside on a Stealthburner, Xol or A4T. The nozzle and heatbreak are one part, so you swap it by hand in seconds, cold, without re-tightening anything hot.
Brass: the everyday nozzle for PLA, PETG, ABS and ASA
High Flow: about 70% more flow in the same form factor, for fast profiles
ObXidian / ObXiDian 500: abrasion-resistant coatings for CF, GF and other filled filaments
HTA and High Temperature copper: for PEEK, PEI and other engineering materials
Revo nozzles are E3D-only; clones don't seal or heat the same way. All stock here comes through E3D's own trade channel and ships from the Netherlands.
