V4 clogged nozzle - where can I find spares?

I clogged two of them and don't have spares now. Where can buy spare ones? I found nozzles for V3 hotends on the MakerGear site but not for V4.

I am using PETG (love that stuff) and it seems to clog the nozzle once in a while.

Thanks

I think that one is still on the Upgrades page:

Found the nozzle page under Upgrades. Seems weird that V4 is still considered an upgrade given that this is the standard hotend for a year or more...

Burn your clog out with a torch (assuming it can be unscrewed from the v4). Works like a charm.

I just wonder how many of these clogs are just stripped filament. Are people getting failures to extrude and just pulling nozzles ? I think in all the years since the V4 released I have only had to unclog via blow torch once. And the only time you replace a nozzle is from extreme wear. Which does happen with a lot of printing.

I am playing with tungsten filled ABS and facing this problem daily ...
at 0.35 printing is very stable but all attempts to go 0.25 finished with clogging (so many paramaters studied ...)
for ABS I found acetone soaking overnight is sufficient to soften the plug enough to scarp some plastic and blow it with clear ABS

I am guessing...from a source of some practical experience...having ran .25 nozzles with other specialty filaments that it may not be possible to print that filament with a .25. I assume you already tried slowing your print speed down and upping nozzle temperature ? Some manufacturers flatly state you need .35 or larger for their filaments. :D

I had a couple of clogs with a V4 .35 nozzle - turns out there was a piece of filament hanging out in the extruder I burned one tip out with a torch, however I found it was more elegant to sit the nozzle on the grate on my gas stove and run it on medium for about 10 minutes. It cleaned it up like new.
