PEX Plumbing Tubing

Merflex® PEX OT® Plumbing Tubing

The unique properties of Merflex PEX  OT tubing produced by Mercury Plastics offers distinct performance advantages for a variety of plumbing applications.

Merflex PEX TubingMerflex PEX  OT tubing is easy to install and provides long-term performance in potable water applications, withstanding high temperatures, corrosion, expansion, contraction, abrasion, high pressure and water hammer conditions.

In addition, our irradiation cross-linking process is clean, safe and environmentally friendly.  Irradiation cross-linking does not require any chemical additives.  The result is a PEX-C tube that provides:

  • Superior odor and taste properties
  • Increased material stability
  • Extremely consistent dimensional properties
  • Improved resistance to creep
  • Increased tensile and impact strength
  • Increased material strength
  • Improved chemical resistance
  • Improved kink resistance

All of our PEX tubing is manufactured in Middlefield, Ohio.  It is available in a variety of colors, including: red, white, blue and gray.  It can be provided in tube sizes ranging from 1/4″ to 1-1/4″ in diameter in various coil lengths and cut lengths.
