I had hopes that this tube, not having a flange to seat at the top of the block, would be able to go a little further down and have the nozzle seat against it and prevent leaks. Futile hope, molten plastic puddled everywhere, top and bottom, ended up burning off the extruder block to get rid of the last of it. Mechanically, there's nothing against this part, it's very well made and fits the Micro Swiss parts like the originals. The problem is the design of the head, not this part. I never did get a good print with the Micro Swiss extruder, have gone back to the teflon-lined one, prints PETG perfectly with that. ### ⭐⭐⭐⭐⭐ Does, in fact, work for the Creality hotends. *by B***D on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 17, 2020* This heatbreak is only as long as it needs to be. It does not fill the entire space inside the stock heatsink - but the slot lines up with the grub screw, which makes the break sit flush with the bottom of the heatsink, exactly where it should. PTFE fills the rest of the space, and is in no danger of melting.I purchased these a while ago, and the price was reasonable at the time. Now that other options are available, this is one of the most expensive titanium heatbreaks you can buy. The quality and performance are great - but other options provide the same for far better prices. ### ⭐ Does not even fit the micro swiss heat sink as advertised! *by W***M on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 1, 2022* I bought this to replace the heat break on the all metal micro swiss hot end I purchased as an upgrade and never was able to get it to stop clogging. I had to use a torch to get the old heat break out of the heat block and ruined it doing that but this replacement heat sink is completely designed wrong to fit the micro swiss heat sink. its flat at the top and does not fit into the groove in the bottom of the heat sink! complete waste of money!! buyer beware if you plan to use this with a micro swiss hot end and I have no idea what it would even fit! will call support and return asap! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/104420688-1x-tc4-titanium-alloy-thermal-heat-break-throat-for-cr](https://www.desertcart.us/products/104420688-1x-tc4-titanium-alloy-thermal-heat-break-throat-for-cr) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-05*
