Bondtech CHT High Flow Nozzles MK8 Nickel Coated Brass Various Sizes

High-flow nozzles are essential for CoreXY and Cartesian printers pushing speed and volume, where insufficient melt capacity leads to under-extrusion and weak layer adhesion. Without optimized nozzles, prints risk poor strength and surface quality, especially on high-speed Voron, Ender 3, and BMG-equipped setups.

The Bondtech CHT High Flow MK8 Nickel Coated Brass Nozzle enhances your hotend's melting capacity by splitting filament into three thinner strands, enabling faster melting and higher volumetric flow rates. Designed for MK8 hotends, it supports both 1.75mm and 2.85mm filaments and comes in sizes from 0.40mm up to 1.8mm, ideal for Voron 2.4, Ender 3 Pro, and other MK8-compatible printers. The nickel coating reduces corrosion and abrasion, improving filament feed and reducing plastic adhesion for consistent extrusion and longer nozzle life.

Why Upgrade?

• Increase melt capacity for faster print speeds on Voron 2.4 and Trident CoreXY builds
• Improve layer adhesion and part strength on Ender 3 and Ender 3 Pro printers
• Reduce nozzle wear and filament jams with nickel coating, especially when printing abrasive or composite filaments
• Enable reliable high-flow extrusion for flexible and rigid filaments in 1.75mm and 2.85mm formats
• Compatible with BMG extruder upgrades requiring precise, high-volume melt rates

Best For:

• Voron 2.4 and Trident builders seeking higher volumetric flow rates
• Ender 3 and Ender 3 Pro users upgrading to high-flow nozzles for faster prints
• CoreXY and Cartesian printers using MK8 hotends requiring nickel-coated durability
• Users printing flexible TPU and rigid PLA filaments at high speeds
• 3D printing enthusiasts needing multiple nozzle sizes for different materials

Pair With the Right Filament

Optimizing your nozzle flow capacity pairs well with filaments that demand consistent extrusion and strong layer bonding.

• PLA Filament — ideal for high-speed prints with excellent layer adhesion
• TPU Flexible Filament — benefits from smooth extrusion enabled by nickel coating
• PETG Filament — requires reliable melt flow for strong, durable parts
