Ecoflex potable PEX single pipes are designed for potable-water distribution applications. The Uponor AquaPEX service pipes in Ecoflex potable PEX piping are manufactured by the Engel-method (PEX-a) process and are listed to ASTM F876 and F877. The pipe is surrounded by multi-layer, closed-cell, PEX-foam insulation and a water-resistant, corrugated HDPE jacket, making it ideal for direct-burial applications.
