DescriptionThe product include Mk8 nozzle, PTFE tube cutter, MK8 protective silicone cover case and quick pneumatic connector. MK8 Silicone made of heat-resistant, non-stick silicone material, much more durable and functional, heat resistant. The 3D printer nozzles are made of brass material, sturdy and durable, solve the problem of plugging and missing materials to the greatest extent, low thermal conductivity, resistant to corrosion, high abrasion resistance. PTFE tube cutter less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder, and less clogging when printing chunky filaments such as some woodfills or ironfills.Features- Color: Assorted Color.- Material: silicone.- Size: 100 x 0.4 x 0.4cm/ 39.37 x 0.16 x 0.16 inch.- The 3D printer nozzles are made of brass material, sturdy and durable.- MK8 Nozzle through long-term testing to solve the problem of plugging and missing materials to the greatest extent, low thermal conductivity, resistant to corrosion, high abrasion resistance.- MK8 Silicone can extend the life of the heater block and keep your heater block clean from burnt and blackened plastic.- MK8 Silicone don't just keep the block clean, but also keep heat inside the hotend and off your print.- PTFE tube cutter less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder, and less clogging when printing chunky filaments such as some woodfills or ironfills.
