Multi-layer PEX-AL-PEX tubing with an aluminum core. The collection includes MrPEX Systems silver PEX-AL-PEX tubing in 1/2" x 1000 ft and 5/8" x 400 ft coils.
The aluminum layer acts as an oxygen barrier and helps the tubing hold its shape when bent, which suits radiant heating and exposed runs. Use fittings rated for PEX-AL-PEX, since the outside diameter differs from standard PEX. Check the pressure and temperature ratings and the coil length for the loop lengths planned.
