Legend Valve 101-151NL 3/4" FNPT Union x Sweat NL Tankless Valve Kit

Tankless water heater valve kit

The Legend Valve 101-151NL kit provides a 3/4 inch FNPT union and sweat connection for tankless water heater installations. It is built without a pressure reducing valve and uses no-lead compliant materials. This kit suits plumbers and contractors who need a direct sweat-to-union transition for new or replacement work.

Union and sweat connections in a single kit

The FNPT union allows quick disconnection for service while the sweat end joins copper pipe with standard soldering practice. No-lead construction meets drinking-water regulations and the absence of a pressure reducing valve keeps the assembly compact. Installers gain a streamlined component set that reduces joint count on the hot and cold supply lines.

No-lead brass handles sustained potable-water duty

The brass body resists dezincification and withstands continuous hot-water circulation without leaching lead above regulatory limits. California Proposition 65 warnings apply because the alloy contains listed chemicals. The kit is intended for tankless heater service where constant temperature cycling and pressure fluctuations are normal operating conditions.
