1 in. PEX-A x 1 in. Female Copper Sweat Elbow (NSF Lead Free Brass F1960 PEX Cold Expansion Fitting)

The 247Garden 1-inch PEX-A x 1-inch Female Copper Sweat Elbow is a premium-quality brass plumbing fitting engineered to connect 1-inch PEX-A tubing to 1-inch copper pipe at a 90-degree angle. Designed for professional performance, this fitting combines the durability of lead-free brass with the proven reliability of ASTM F1960 cold expansion technology. NSF certified for potable water, it provides a secure, leak-resistant, and code-compliant solution for both residential and commercial water distribution systems.

This elbow fitting is perfect for transitions where PEX-A and copper piping need to work together in the same system. On one side, the PEX-A connection installs quickly with an expansion tool and expansion rings. On the other, the female sweat end allows for a strong soldered connection to copper tubing.

Installation Instructions

Step 1: Install the Copper Side First

1. Cut the copper pipe clean and square.

2. Clean both the pipe exterior and the fitting interior with emery cloth or a wire brush.

3. Apply a thin coat of lead-free flux.

4. Insert the copper pipe fully into the female sweat fitting.

5. Heat the joint evenly with a propane torch. Apply lead-free solder until it flows around the joint.

6. Allow the joint to cool naturally. Do not quench with water.

7. Wipe off excess flux residue once cooled.

Step 2: Connect the PEX-A Side

1. Cut the 1-inch PEX-A tubing squarely using a PEX cutter. Ensure it is free of burrs or deformities.

2. Slide a 1-inch PEX expansion ring over the end of the tubing.

3. Expand the tubing using a calibrated PEX expansion tool. Rotate the tool slightly between expansions for a uniform opening.

4. Immediately insert the fitting’s PEX end into the expanded tubing until it seats fully against the fitting shoulder.

5. Hold in place for a few seconds. The tubing will contract around the fitting, forming a secure, watertight seal.

Tips and Tricks for Best Results

• Always solder copper first. Heat from the torch can damage PEX-A if installed prematurely.

• Use only lead-free flux and solder for potable water applications.

• Avoid overheating. Excessive heat can scorch the fitting or cause poor solder flow. Apply steady heat and let the solder wick naturally.

• Clean thoroughly. Any oxidation, burrs, or leftover flux can compromise the joint. Take time to prep properly.

• Do not rush the PEX contraction. Allow the tubing to naturally shrink over the fitting for the tightest seal.

• Protect from flame. Keep PEX tubing and fittings far from any torch work.

• Pressure test the system before putting it into service to confirm watertight performance.
