No more stripped threads

The hardened steel holds up much better during frequent changes than standard brass. Very happy with this purchase.

Perfect upgrade for abrasive filaments

I switched to this hardened steel nozzle to print carbon fiber PLA and it works flawlessly. No clogging and the flow is consistent.

Essential for the Neptune 4 Pro

If you plan on doing any serious printing with composite materials, this is a must-have accessory. Fits perfectly on my Neptune 4.

Durable and reliable

Been using this for three months now with glass-filled nylon. The tip shows no signs of wear compared to my old brass nozzle.

Good value for money

Solid construction. Print quality improved slightly due to better heat retention. Would recommend keeping a spare.

Great quality but needs careful installation

The nozzle itself is excellent quality. Just make sure to tighten it while hot to avoid leaks. Prints look sharp.
