Anyone know what gasket is needed for the M5-4 fitting on a Core One?

I've had "clicky extruder" issues on my new Core One and had to remove the feeder PTFE tube fitting (this one https://www.prusa3d.com/product/fitting-m5-4/) to get to the stuck filament. Did it twice, and the gasket on it is now totally ruined. I know the fitting is sold on the shop, but I just need the gasket. Anyone know where I can get one? Or is it easier to just get a new fitting?

 

 

Best Answer by James Kirk:

Try it without the gasket.

The original purpose for these kind of fittings is to connect tubes with pressurized air.

If you don´t use it for pressurized air, you don´t need the gasket.

Yeah, I've been using it without the gasket but was wondering if it was needed for something. Prints fine without it, so that makes sense! Thanks
