The ProPEX Lead-free (LF) Brass Tee makes diverting connections for Uponor PEX-a pipe for use in hot and cold domestic potable water systems, residential fire sprinkler systems, hydronic distribution piping, and radiant heating and cooling systems. Each end of the tee is manufactured with an Uponor ProPEX fitting for connections to Uponor AquaPEX pipe. Combine with Uponor PEX-a pipe, Uponor ProPEX EP fittings, Uponor LF brass valves, and Uponor ProPEX out-of-the-wall support systems for a complete lead-free solution from inlet to faucet without the need for torches, glues, solvents, gauges, or fire-watch requirements. The ProPEX connection system also eliminates dry-fit concerns for a more reliable solution. Note that the ProPEX connection requires the use of a ProPEX expansion tool and ProPEX rings (sold separately).
