Faster installation compared to rigid pipe. Flexible pipe reduces the number of connection points while reducing cost, time and potential leak points. Freeze-resistant pipe can expand slightly if frozen and contract when thawed. Ideal for hot and cold potable water distribution, fire protection and municipal water service lines.PEX-A offers the highest rated flexibility and one month UV resistanceApproved for water service lines and burial applications including being buried under concreteCertified to meet ASTM F2023 oxidative resistance requirements for continuous hot water recirculation
