E3D Revo vs V6: nozzles, fit and what changes
Revo nozzles do not fit V6 heater blocks. How each system changes nozzles, what Revo Six replaces, E3D's temperature ratings and the Z offset check.

Short answer
Revo nozzles do not fit V6 heater blocks, so moving to Revo means replacing the hot side, not just the nozzle. Revo nozzles change by hand when cold; V6 nozzles are tightened hot. E3D sells Revo Six as a drop-in for V6-fitted printers, and either way you should check your Z offset after a nozzle change.
The short answer: they are different systems
E3D states that Revo nozzles are not compatible with V6-style heater blocks.[1] A Revo nozzle is a nozzle and heat break made as one unit. A V6 nozzle is a separate part that screws into a heater block with an M6 thread.[2]
So you cannot buy Revo nozzles to use in a V6. You either keep the V6 and its nozzles, or you change to a Revo hotend.
How each one changes nozzles
E3D describes each Revo nozzle as a preassembled nozzle and heat break that you change by hand when the hotend is cold, with no hot tightening and no special tools.[1]
V6 nozzles are different. E3D's V6 guide says to hot-tighten brass nozzles at 285 °C to about 2 Nm, and its other nozzle materials at 20 °C above your printing temperature.[3] That procedure belongs to E3D V6 nozzles only. For other makers' torque figures, see how tight a nozzle should be.
Revo Six as a V6 replacement
E3D describes Revo Six as a drop-in upgrade for V6-fitted printers, with the same height, diameter and mounting as the V6.[4] The same article says older E3D parts lose compatibility with Revo parts. "Drop-in" here covers the geometry. It does not tell you whether your board, heater wiring or firmware settings match, so read your printer's documentation and the kit's instructions before ordering.
Temperatures and materials
| E3D V6 | E3D Revo | |
|---|---|---|
| Nozzle fit | M6 thread into a V6 heater block | Nozzle and heat break in one unit, Revo hotends only |
| Nozzle change | Hot-tighten (brass at 285 °C, about 2 Nm) | By hand, cold |
| Brass nozzle rating | 300 °C | 300 °C (standard brass) |
| Other nozzle ratings | 350 °C hardened steel; 500 °C stainless, plated copper, Nozzle X | Not covered here |
| Filament | 1.75 mm brass nozzles described | 1.75 mm; 2.85 mm not offered as standard |
E3D rates V6 nozzles at 300 °C for brass and ObXidian, 350 °C for hardened steel, and 500 °C for stainless steel, plated copper and Nozzle X.[3] It describes its 1.75 mm V6 brass nozzles for standard non-abrasive printing such as PLA, PETG and ABS.[2] The standard brass Revo nozzle is listed at 300 °C for 1.75 mm filament, and E3D says 2.85 mm Revo nozzles are not offered as standard.[1]
These are nozzle ratings. The usable limit of a whole hotend also depends on its heater, temperature sensor, heat break and firmware.
HeaterCore: 40 W or 60 W
E3D says the standard 40 W HeaterCore is enough for most Revo High Flow use, and recommends the 60 W core for high-temperature materials such as polycarbonate.[5] A heater change is an electrical change: match the voltage your printer uses and follow E3D's instructions. If you are not sure, ask the maker or a qualified technician.
Z offset after a nozzle swap
E3D says Revo nozzles are made to the same length within ±0.2 mm.[5] It still notes that you may need to adjust your Z offset when changing nozzles.[1] A same-length tolerance is not a promise that your first layer is unchanged, so check it every time. The bed probe and mesh guide covers what else invalidates an offset.
A Revo kit for the Ender 3 family
Micro Swiss makes an NG REVO direct drive kit that carries an E3D Revo hotend, in 24 V and 12 V versions.
Picks that fit1 product
Only for a Creality Ender 3, Ender 3 Pro, Ender 3 V2 or the CR-10, CR-10s, CR-10-S4 or CR-10-S5 running on 24 V: choose the 24 V version (M3301).

Questions
Can I put a Revo nozzle in my V6 heater block?
No. E3D states that Revo nozzles are not compatible with V6-style heater blocks.[1]
Is Revo Six a drop-in replacement for a V6?
E3D describes Revo Six as a drop-in upgrade for V6-fitted printers, with the same height, diameter and mounting as the V6. That covers the geometry, not wiring or firmware.[4]
Do I need to redo the Z offset after changing a Revo nozzle?
Check it. E3D says you may need to adjust your Z offset when changing nozzles, even though it makes Revo nozzles to the same length within ±0.2 mm.[1][5]
What temperature can Revo and V6 nozzles take?
E3D lists the standard brass Revo nozzle at 300 °C. It rates V6 nozzles at 300 °C for brass, 350 °C for hardened steel and 500 °C for stainless steel, plated copper and Nozzle X. The whole hotend's limit also depends on its heater, sensor, heat break and firmware.[1][3]
