I don't know, but a quick search pulled this up, still lookin though.
Compatible with compression type PEX fittings and Press type connection system.
PEX-AL-PEX tubing is a composite type tubing comprised of 3 layers (PEX, Aluminum and PEX) bonded together. Since aluminum is impermeable to oxygen, it acts as an effective oxygen diffusion barrier and eliminates the need for an additional EVOH layer (as in barrier PEX), making it suitable for hydronic and radiant heating applications, including warm floors, baseboard/radiator systems, snow melt systems and others.
