PEX-B White Tubing Coil for Residential & Commercial (Non-Barrier)
PEX-B is made using a "Silane" or "Moisture Cure" method of cross-linking, where links between the molecules of the HDPE polymer are formed after the extrusion process using a catalyst and by exposing PEX tubing to water (steam bath). Pexflow tubing conforms to NSF, UPC, ASTM and Warnock Hersey standards.
Tubing is marked every 5ft with length, ASTM standards, approvals, certifications, pressure ratings and other technical information.
