Uponor's lead-free brass transition fittings, valves and wall boxes carry the NSF us-pw-G marking for lead-free compliance to meet state lead-free legislation, and exceed the U.S. Safe Drinking Water Act. Now you can combine lead-free brass fittings with Uponor's PEX tubing, EP offering and ProPEX Out-of-the-Wall Support System for a complete lead-free solution from the inlet to the faucet. The new lead-free offerings feature Uponor's unique ProPEX fitting system for strong, durable connections without the need for torches, glues, solvents or gauges.
