Printing with an Olsson Ruby nozzle is a substantial upgrade to your 3D Printer. The Olsson Ruby works with a huge range of materials like PLA, ABS, CPE/PET, Nylon, and composites with abrasive additives such as Carbon fibre, Steel, Wood, Boron Carbide, Tungsten and Phosphorescent pigment. Since most of the Olsson Ruby is made from brass, with its excellent heat conductivity, performance and throughput is first-class. The Olsson Ruby is manufactured, assembled and tested in a high-quality facility in Sweden. This is why 3DVerkstan guarantees the very best quality and tolerances. Item Specifics Nozzle Size: 0.40mm Filament Size: 1.75mm Body Material: Brass

Clearly out of spec.
If you look at the picture for the proper specs of an Mk8 Nozzle they should measure 13mm tip to butt with 5mm of threads. My example was 13.5mm in length with 5.5mm of threads, preventing it from properly seating against the heating block. My hardened steel Swiss Micro nozzles are all in spec and tight properly against the block. I decided to try the Olsson Ruby for it's superior heat transference, but since won't properly seat against the heating block, so not sure if this is due to poor quality control or poor design it's unacceptable at this price.

Great product
Great product.However, I noticed that the MK8 thread is a little bit bigger than the standard MK8 thread. I happen to have a Direct Drive Extruder and, when I installed the Olsson Ruby Nozzle, I had issues to do the bed leveling because this small difference made it be below the bed. I had to workaround, and I still can use it. Just one small inconvenience though.
