Mercurry Barrel Stainless Steel Nozzle Throat with Teflon Tube for E3d V6 3D Printer 1.75mm Extruder Hot End

I found that these heat breaks are actually stronger than an official E3D heat break, making them less likely to get damaged. The machine marks on the threads aren't perfect, but that doesn't really matter since it uses a teflon tube where the filament would touch them. The only real downside to them is that they're teflon lined, meaning you really shouldn't take them above 260C or so.

I had been fighting with a e3d v6 clone for at least 2 weeks. I replaced *everything* but the extruder throat and always had jams. These solved the problem and I am now printing at 15 degrees below where I was with the original hotend. I cannot be happier. I just re-ordered for more spares.

Fixed our problems with filament binding up in the throat of a E3d Clone. Got plenty of extras for a dual extruder setup here soon. If your E3d clone is having feeding problems it's not the extruder it's the nozzle throat and no tubing in it but this one has it and will fix all the problems

I even ran these at 260C to see if they would melt and they performed great. I'm using them at 230C regularly for printing recycled PET. I haven't had a jam because of these yet. They were a great replacement for my all metal heatbreaks that kept jamming.

Not what I needed but kept them as they are decent quality and I may be able to use them in the future.

These work very well in my E3V6 clone. Very reasonable price for what you get.

Worked like a charm. Replaced the original one that I had snapped off my Prusa.

Not good for monoprice 15365 I am giving it 5 stars because they look amazing just not compatible.
