1" x 3/4" No-Lead Bronze Pack Joint Union

The Legend Valve 313-247NL T-4321NL union joins a 1-inch pack joint connection to a 3/4-inch pack joint connection. It is built for potable water lines where a no-lead bronze fitting is required. Plumbers and municipal crews use it to transition between different service sizes without soldering.

Pack joint connection limits

The fitting relies on a compression-style pack joint seal that grips polyethylene or CTS tubing when the nut is tightened. It does not accept flare, press-fit or threaded pipe ends without a separate adapter. The joint is rated for standard water service pressures but is not designed for gas distribution or high-temperature hydronic loops.

No-lead bronze construction

The body is cast from no-lead bronze alloy to meet federal and California Proposition 65 requirements for drinking water contact. Pack joint nuts and gaskets are included so the union can be assembled on site with common wrenches. The product carries a Proposition 65 warning for chemicals known to cause cancer and reproductive harm.
