Heater Block Upgrade with Silicone Sock for CR10 / Ender 2 / Ender 3 / ANET A8 Printers MK7, MK8, MK9 Hotends

My old heat block suffered galvanic corrosion between the stainless pinch screws and the aluminium block causing the pinch screws to seize and break off during disassembly of the hot end. I have put a barrier paste and hope this one lasts longer

I got these cause I realized the block on my printer didn't seem to have any threads left inside where the rod and nozzle goes and was causing major leaks. I put one of these new ones on and not a single leak and the difference in print quality has been amazing! I love the new heat block and so glad friend gave me a gift certificate so I was able to get extras.

Great quality and great shipping

Needed a replacement heat block. Buying direct was not only cheaper but it was faster than buying on amazon.

This company and it's people just go out of their way to help.
