3/4″ No-Lead Brass Union

This 3/4″ no-lead brass union joins a sweat copper connection to a male NPT thread. It suits residential and light-commercial plumbing where lead-free materials are required by code.

California Proposition 65 notice

The product carries a Proposition 65 warning for a chemical known to the State of California to cause cancer and a chemical known to cause birth defects or other reproductive harm. Installers should follow local safety practices when handling and soldering the fitting.

Sweat-to-MNPT configuration

The sweat end accepts standard 3/4″ copper tube for soldered joints while the MNPT end threads into female NPT ports on valves, tanks or equipment. Brass construction resists corrosion in potable-water systems and the union nut allows the connection to be broken for service without cutting pipe.

Questions about this item

How is the 302-307LNL union installed on the sweat end?

Clean the copper tube, apply flux, slide the union on, and heat evenly until solder flows; the step often missed is removing the internal sealing washer before heating so it does not melt.

What part of the 302-307LNL will need replacement first?

The internal sealing washer between the sweat and MNPT halves degrades over time and should be replaced if the joint begins to weep.

What limit appears first when the 302-307LNL is under sustained hot-water use?

The no-lead brass body handles continuous hot water, but the sealing washer softens at elevated temperature and will leak before the metal fatigues.
