No

Very different, Fosta is essentially a standard SDR9 pipe once the outer layer is shaved off. Some use viega press sleves with other brands of SDR9 pipe. Multi core is different : Different tools, sleeves, O-rings, metric diameters, Biggest difference is that the sleeve compresses over all of the layers as opposed to fosta where this outer layer is shaved off.

What gave you the idea you could interchange these anyway?

sleeves and the tools...
