Ecoflex pre-insulated pipe is now offered in 1, 1¼ and 1½ inch ASTM sizes. ASTM Ecoflex features hePEX plus barrier tubing surrounded by closed-cell, PEX-foam insulation and covered by a waterproof, corrugated HDPE jacket, making it ideal for direct-burial applications. It is available in continuous lengths up to 600 feet, and uses either durable ProPEX fittings or the new WIPEX dezincification-resistant (DZR) brass compression fittings for a watertight, leak-resistant system. Ecoflex is available in single and twin configurations which feature one or two hePEX plus service pipes, respectively. The long coil lengths eliminate most buried connections and pipe joints, saving time and money while also reducing the risk of potential leak points.
