5/8 x 300' hePEX Barrier Tube Coil, Heat Transfer, White

Product Overview

The Uponor A1250625 HePEX™ Barrier Tubing is an oxygen-barrier, crosslinked polyethylene (PEX-a) tube engineered for hydronic heating and cooling distribution systems. Designed for long-term performance in pressurized applications, the tubing incorporates an EVOH oxygen diffusion barrier that prevents corrosion of ferrous system components. Supplied in a 300-foot coil, this 5/8-inch nominal tubing supports radiant, snow melt, and hydronic baseboard systems requiring durable, code-compliant piping.
