PRODUCT DESCRIPTION Simplify your plumbing projects with the SharkBite PEX-B pipe available in coils up to 1,000 feet in length, allowing longer runs and fewer connections to save time, money, and potential leak points. Ideal for hot and cold potable water distribution, fire protection, and municipal water service lines, this flexible PEX tubing expands and contracts as water freezes and thaws within the pipe. The innovative push-to-connect design of the SharkBite brass PEX water tubing offers faster installation compared to rigid pipe, six-month UV resistance, and the highest-rated chlorine resistance. These portable PEX tubings are certified to meet ASTM F2023 oxidative-resistance requirements for continuous hot water recirculation and are approved for water service lines and burial applications including being buried under concrete. SharkBite water pipe tube features a minimum working temperature of 33 degrees F at 160 PSI, a maximum working temperature of 200 degrees F at 80 PSI, and a maximum working pressure of 160 PSI at 33 to 70 degrees F.
