Merflex® Geothermal Pipe

The Merflex Geothermal Pipe Advantage

Merflex Geothermal Pipe is manufactured using high density polyethylene (HDPE) specifically designed to be used for geothermal applications. Using the highest quality NSF approved 3408/3608/4710 material available, Merflex Geothermal Pipe is made in compliance with ASTM Standard D-3035 to ensure reliability and quality every time.

Utilizing our state-of-the-art in-line computer measuring system, the diameter and wall thickness of our pipe is automatically measured and documented every 2 seconds. This allows us to maintain very tight tolerance on diameter and wall thickness which helps ensure a superior fit when joining with fittings.

Backed by a 50-year warranty, Merflex Geothermal Pipe is approved in sizes from 3/4" IPS to 2" IPS and can be custom ordered to specific lengths. Standard color is black with numbered footage marks every 5 feet.
