I bought some new nozzles that r not identical to the original e3d style.
The stem is about 4mm shorter than the orig.
I like them because they do not have a flat spot on the face that I think is causing issues.
I like they way it works, ONLY problem is sealing the PLA in.
Because of the short shaft it will not butt against the barrel to seal.
I have not disassembled to see if I can screw the barrel in another 4-5mm to get the proper seal but if I can I may not have any heat break left.

Is there another method I can use to seal it or do I have to abandon these?
any other ideas?
