3/4" No Lead Sweat Union
The Legend Valve 302-304LNL is a 3/4 inch sweat-by-sweat union made from no-lead brass. It joins two copper pipes in a permanent, leak-tight connection for potable water lines. The fitting meets low-lead requirements for safe drinking water installations.
Installers needing a lead-free sweat joint
This union suits plumbers and DIYers joining copper tubing in residential or light commercial systems where no-lead brass is required. It will not work for threaded, press-fit or push-to-connect pipe ends. Buyers who need a different joining method or a larger diameter should look at other fittings.
Sweat installation with standard tools
A propane torch, flux and lead-free solder are all that is required to make the joint. The most common issue is overheating the brass, which can damage the seat or cause solder to run where it is not wanted. Clean the tube ends thoroughly and apply heat evenly for a reliable seal.

Questions about this item
What copper pipe size must I already have for the 3/4" sweat connections to fit?
You need 3/4" copper tubing so the sweat ends can be soldered directly onto the pipe.
Will the no-lead brass union join safely to older leaded brass fittings in my system?
Yes, the 3/4" sweat ends solder to any clean copper or brass fitting regardless of lead content.
How can I verify the union is sealed after soldering both joints?
Pressurise the line and check for leaks at each sweat joint; a dry joint confirms the seal.
