All PEX

meets the same standards for Temp and Pressure ratings. See ASTM F876. Read the print line on the pipe and it will list all of the details.

Does not matter how the PEX is extruded.

All extrusion methods are similar

It the cross-linking process that changes high density poly ethylene to PEX is what determines PEXa b or c. which in the industry are known as the Engel, Silane or electron beam processing methods. Cross-linking changes the material from a thermoplastic to an elastomer... Fun stuff huh?
