Viega PureFlow PEX 1 in. white coil tubing is designed for potable hot- and cold-water distribution in residential and commercial construction. The 300 ft. coil supports long, flexible runs that can reduce the number of directional fittings and concealed joints compared with rigid piping layouts. PEX 5306 tubing provides documented chlorine resistance for continuous domestic hot-water circulation up to 140°F and six months of UV resistance. It integrates with Viega PureFlow Press, PureFlow Crimp and ManaBloc system components, giving projects a coordinated tubing and fitting platform for home-run, combination, branch-and-tee and hybrid piping layouts. The flexible coil can be routed around common building obstructions, helping simplify installation while maintaining a reliable, code-listed potable-water system. Material: Cross-Linked Polyethylene (PEX).
