  • No-lead bronze construction for safer potable water

3/4 x 1 Flare to MIP Coupling

This no-lead bronze coupling connects a 3/4 inch flare fitting to a 1 inch male NPT thread. It is intended for potable water lines where lead-free components are required. The T4100NL body meets low-lead standards for drinking water installations.

Replaces Leaded Bronze Couplings

Use this fitting when local codes mandate no-lead alloys or when swapping out older leaded bronze couplings during repairs. The change is justified on projects that must comply with Proposition 65 restrictions on lead content in drinking water systems.

Fits Flare and MIP Connections

The flare end accepts a standard 3/4 inch flare nut and tubing while the MIP end threads into a 1 inch female NPT port. No soldering or pressing tools are needed, freeing up time on service calls where a quick thread-to-flare transition is required.
