What is PEX A tubing?

The term PEX A comes from European standards and is not a rating system of any kind. PEX A tubing refers to PEX Tubing made using the Engel Method of crosslinking. This can get quite technical but for those who are interested we will provide information on the Engel method in more detail.

According to www.pfahome.org "The "Engel" or peroxide method employs a special extruder with a plunger action where peroxide is added to the base resin and through a combination of pressure and high temperature the cross-linking takes place as the tubing is produced."

WIrsbo PEX Tubing and Mr. PEX Tubing are PEX A Tubing made using the Engel Method.

What is the difference between Wirsbo Aquapex Tubing and Wirsbo HePex PEX Tubing?

Wirsbo makes several different models of PEX Tubing. The two most popular are the Wirsbo Aquapex and Wirsbo HePEX Tubing. There is a distinct difference between these two products. Wirsbo HePEX Tubing has an oxygen diffusion barrier to prevent rusting of metal components. Therefore HePEX is designed for use in radiant heat systems. Conversely, Wirsbo Aquapex doesn't have an oxygen barrier and is designed for potable water (drinking water) systems.

Why is PEX Tubing different colors?

PEX Tubing comes in many different colors. These include white, red, blue, orange, and several others. The color of the PEX is mainly used to distinguish hot and cold lines in potable water systems. For radiant heat, different manufacturers may use different colors. However, there is no material difference from one color to another. Difference in PEX Tubing comes from the way the tubing is made and the material that is used to create it.

When do I need an Oxygen Barrier for PEX Tubing?

PEX Tubing comes in several forms. When installing a radiant heat system that contains ferrous (metal) materials, you must use a PEX Tubing w/ an oxygen barrier. This tubing will prevent rusting of the metal components in the system. If there are metal componenets and the installed tubing doesn't have an oxygen barrier, the components will rust. Metal components in a hydronic heating system might include pumps, valves, and anything else that may come into contact with water.
