Installation Instructions

Copper Sweat Side:

1. Clean the outside of the copper pipe and the inside of the female sweat fitting with emery cloth or a wire brush.

2. Apply a thin, even layer of lead-free soldering flux to both surfaces.

3. Insert the copper pipe into the female sweat elbow until it bottoms out.

4. Heat the joint evenly with a propane torch and apply lead-free solder. Allow the solder to flow completely around the connection.

5. Remove heat and let the joint cool naturally before pressurizing the system.

PEX-A Side (Expansion Connection):

1. Cut the 3/4-inch PEX-A pipe squarely using a PEX cutter. Ensure the end is clean and free of burrs.

2. Slide a 3/4-inch PEX expansion ring over the end of the pipe.

3. Insert the pipe into the expansion tool and expand the tubing fully according to the tool manufacturer’s instructions. Rotate slightly between expansions for an even fit.

4. Immediately insert the PEX-A pipe over the brass end of the fitting until it seats fully against the shoulder. The pipe will contract over the fitting, forming a secure connection.

Why Choose 247Garden Brass Fittings:

• Manufactured from durable lead-free brass

• Certified safe for potable water systems

• Designed to meet the highest plumbing standards

• Engineered for secure and leak-resistant transitions

Note:

1. Always prepare and solder the copper side first.

• The sweat joint requires heating with a propane torch. If you install the PEX-A side first, the heat from soldering can damage the PEX pipe and fitting.

• Clean, flux, insert, heat, and solder the copper pipe into the female sweat elbow.

• Allow the joint to cool naturally. Wipe off any excess flux residue after cooling.

2. After the copper side is completely cooled, install the PEX-A side.

• Slide the expansion ring onto the PEX-A tubing.

• Expand the PEX-A pipe with the expander tool.

• Insert the fitting until the pipe seats fully against the shoulder.

• Let the pipe contract over the fitting to form a watertight seal.

Important Tips:

• Never quench the soldered copper joint with water; let it cool on its own before connecting the PEX-A.

• Keep the PEX pipe and fitting away from open flame.

• Always use lead-free solder and flux approved for potable water.

This sequence ensures you don’t expose the PEX material to high heat, which could compromise the fitting.
