Pack of 2pcs 3D Printer Super Smooth Titanium Alloy Heat Break All Metal Thermal Barrel Feeding Tube Heatbreak Throat for 1.75MM V6 HOTEND and Titan Aero Extruder use

Good breaks. Have held up well and worked as they should. Havent had any jams caused by them.

The media could not be loaded. I purchased this, along with a V5 hot end to convert my Monoprice Mini V2 into a higher temp machine. It's part of an overhaul.The original is supplied with a PTFE tube and I wanted an all-metal hot end, titanium heat break, and a new cold end. Titanium heat breaks are slicker than stainless, and superior for this application. The replacement V5 came with a stainless heat break and a PTFE tube. I weighed the stainless heat break that was drilled out for a PTFE tube, and it weighed 3g. This titanium heat break, with the added bulk of not being drilled out for a PTFE tube weighed 1.9g. I may be wrong, but that is more determinate than using a magnet, which will stick to neither material.

This is a very good, high quality replacement for the prusa mk3s heat break that fits perfectly and works great. The ptfe tube fits perfectly and the filament goes thru easily without catching. There are other heat breaks on Amazon that appear to be high quality but the Grove for the ptf tube isn't perfect and causes alot of issues with filament getting stuck as it catches on the edges. Luckily, there are no such problems with this particular product. It appears to be better quality than the original one that was shipped with my prusa!!!

I've been rocking these for a little while now and definitely have them dialed in and get good quality prints with PETG, ABS, and PLA. I had to go to 6mm for retraction on my Tevo Tornado with generic V6 hotend. They're pretty strong too, I've accidently broken others in the past, but these I have not.

I'm pretty much a newbie to 3D printing but not to making pretty metal bits. These are dimensionally accurate, perfectly finished inside and out, and most definitely real titanium. They aren't joking about how well polished they are inside. My only gripe, and it's not enough to warrant even taking one star off, is I wish they'd slightly break the edge of the threads. They're sharper than I'd leave them, but still totally usable. Just use a piece of leather or something between the threads and your fingers when you tighten it.This has M6 threads on the heatsink side and M5 on the nozzle side, and it works perfectly with my other V6 type bits. I've no idea what else it may or may not work with.

Bought these for my volcano v6 hotend and found out that they're a little loose, even having some wobble to them. Not exactly ideal for precision prints, but good enough.

I bought a e3d V6 clone that did not have an all metal heatbreak. I decided since I'd be replacing the heatbreak it came with, I may as well upgrade it to be better than the standard steel heatbreaks. This did the job. No issues running on a modified JGAurora A5.

I can't really say if these are better than "the real thing", but they are cheaper and work great!
