The ProPEX Engineered Polymer (EP) Tee makes diverting connections for Uponor PEX-a pipe for use in hot and cold domestic potable water systems, residential fire sprinkler systems, and hydronic radiant heating and cooling systems. Each end of the tee is manufactured with an Uponor ProPEX fitting for connections to Uponor AquaPEX or Wirsbo hePEX pipe. Combine with Uponor PEX-a pipe, Uponor 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. Note that this product requires the use of a ProPEX expansion tool and ProPEX rings (sold separately) to make the ProPEX connection.
