Unable to remove nozzle from hotend

I've followed the instructions in the manual to remove the nozzle (making sure it's preheated first) but the nozzle just refuses to come off, and at this point quite a bit of brass has been stripped from it in the process of trying to remove it. I am using a wrench to hold the block and pliers to attempt unscrew the nozzle and it absolutely doesn't budge at all. I had this problem the first time I tried to remove a nozzle before I replaced my entire hotend, it seems when they ship it the nozzle is screwed on extremely tight, but this time it's even worse (this is the nozzle that was shipped attached to this hotend), I've tried several pairs of pliers and even getting a good grip on it and turning just strips brass away instead of turning at all

Does anyone have any tips to help remove it?

Grip the block with a good size adjustable wrench, and use a proper socket wrench and correctly sized good quality socket on the nozzle. Pliers are no good.

Edit - Nozzle hex size is 7.0mm

I noticed they show using pliers in the manual but it does make much more sense to use a socket with much less risk of damaging things. I don't own a correctly sized socket wrench, but I will invest in one now for future use. After some immense struggling, and using a wide assortment of tools I was able to remove the nozzle. This nozzle was on there so tightly that I had to practically torture it to death to get it off.

Hi Austin,

Thats a fantastic advert for not using pliers...

How hot did you heat it? it should almost at max temperature 280ish.
