Ecoflex is a pre-insulated pipe system at its best — versatile, flexible and durable. Ecoflex consists of Uponor crosslinked polyethylene (PEX) or high-density polyethylene (HDPE) pipe encased in closed-cell, PEX-foam insulation and covered by a watertight, corrugated HDPE jacket.

The unique properties of Ecoflex make it ideal for commercial and residential applications that require insulated underground piping. These lightweight, flexible, pre-insulated pipes are strong enough to tackle any application, yet install easily and quickly. The long coil lengths eliminate most buried connections, saving time and money while also limiting liability concerns.

PEX is an acronym for crosslinked polyethylene. It is a flexible, durable, corrosion-resistant product that possesses distinctive properties that make it ideal for fire sprinkler, plumbing and radiant floor heating and cooling systems. There are three different types of PEX tubing: PEX-a, PEX-b and PEX-c. Uponor manufactures PEX-a tubing, which is considered the superior type of PEX in the industry.
