Product identity

The Legend Valve 302-317NL is a 3/4 inch copper sweat by FNPT large body union made from no lead brass. It is intended for plumbers and DIY installers joining copper pipe to female iron pipe threads in potable water systems. The transparent finish shows the brass construction. This fitting meets no lead requirements for drinking water applications.

Sustained performance

The no lead brass body resists corrosion and dezincification during continuous water exposure. The large body design provides structural strength for permanent installations behind walls or under floors. Sweat and FNPT connections create reliable joints that withstand thermal cycling and pressure fluctuations typical in residential plumbing. The union allows future disassembly without cutting pipe.

Interface limits

The 3/4 inch nominal size matches standard residential supply lines and restricts use to that diameter. Copper sweat ends require soldering tools and skill while FNPT threads need proper sealant and torque. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm. Orders of $75 or more qualify for free shipping from the manufacturer.

Questions about this item

How much noise or heat does the 302-317NL union generate during continuous water flow?

As a passive brass fitting, it produces no noise or heat of its own; any sound comes from water velocity in the pipe, not the union itself.

What existing pipe and thread types must I already have to install this 3/4" copper-by-FIP union?

You need 3/4" copper tubing ready for sweat soldering on one side and a matching 3/4" female NPT threaded connection on the other.

Will the no-lead brass body of the 302-317NL corrode when joined to older standard-brass valves in my system?

The no-lead brass is compatible with existing brass fittings; galvanic corrosion risk is low in typical potable-water systems.
