For three decades, these samples underwent continuous hydrostatic tests at extreme temperatures and pressures — up to 203åF and 239 pounds per square inch.

Answer
Uponor offers two types of PEX tubing — Wirsbo AQUAPEX® tubing and Wirsbo hePEX™ plus tubing. Wirsbo AQUAPEX® is used in plumbing and under certain circumstances in radiant floor heating systems. Typically, Wirsbo hePEX plus is used for radiant floor heating as it contains an additional layer on the tubing which acts as a barrier and reduces the amount of oxygen entering into the heating system.
