Proper use of copper press fittings can greatly enhance workflow and project efficiency. This guide covers everything you need to know, from their purpose and key installation tips to common mistakes to avoid.

Why choose copper press fittings?

Before diving into the installation process, it's important to understand why copper press fittings are widely used in modern plumbing applications. Some key advantages include:

• Time-saving installation — Press fittings eliminate the need for welding or soldering, allowing for quicker installations with minimal downtime.
• Improved safety — No open flames or hazardous fumes make press fittings a safer option, especially in occupied buildings.
• Reliability — The strong, leak-proof connection ensures long-lasting durability, even in high-pressure systems.
• Versatility — Copper press fittings are suited for a wide range of applications, including potable water, gas and HVAC systems.
• Cost-effectiveness — While initial material costs may be higher, labour savings and reduced risk of errors make press fittings a more cost-efficient choice in the long run.

Applications of copper press fittings in residential and commercial plumbing

Copper press fittings are suitable for various plumbing applications, including:

• Potable water systems — Used in residential and commercial water supply lines.
• HVAC systems — Ideal for chilled water and heating applications.
• Gas lines — Approved for natural gas and propane distribution.
• Fire sprinkler systems — Reliable connections for fire suppression piping.
• Industrial applications — Suitable for high-pressure systems in manufacturing and processing plants.

Step-by-step guide to installing copper press fittings

Installing copper press fittings is straightforward but requires precision and the right tools. These steps can help you create a secure and leak-free connection.

Step 1: Gather the relevant tools and materials

Before starting the installation, check if you have the required tools and components. In addition to your copper press fittings and pipes, make sure you have the following:

• Press tool with the appropriate jaws
• Deburring tool or reamer
• Pipe cutter
• Marker
• Cleaning brush or cloth

Step 2: Measure and cut the copper pipe

Accurate measurement is essential to ensure a proper fit. Use the pipe cutter to cut the copper pipe to the required length. Make sure the cut is clean and even to avoid leaks or improper sealing.

Step 3: Deburr and clean the pipe

After cutting the pipe, use a deburring tool or reamer to remove any sharp edges or burrs inside and outside the pipe. This step is crucial to prevent damage to the O-ring inside the press fitting and ensure a secure connection.

Step 4: Mark the insertion depth

Insert the pipe into the copper press fitting without pressing it yet. Use a marker to indicate the insertion depth. This helps verify that the pipe is fully seated during the pressing process and prevents improper connections.

Step 5: Position the press fitting and tool

Ensure the copper press fitting is correctly aligned with the pipe. Select the appropriate jaw size for the press tool and position it around the fitting. Double-check that everything is in place before proceeding.

Step 6: Activate the press tool

Once positioned correctly, activate the press tool to compress the fitting around the pipe. The tool exerts consistent pressure, forming a secure and leak-proof joint. Most press tools have an automatic shutoff feature to ensure optimal compression.

Step 7: Inspect the connection

After pressing, inspect the joint to confirm a proper seal. Check that the marking on the pipe aligns with the edge of the fitting and that the connection is firm. If necessary, perform a pressure test to verify leak-free performance.

Common mistakes to avoid when using copper press fittings

To ensure a successful installation for your residential or commercial project, avoid these common pitfalls:

• Skipping pipe preparation — Failing to deburr or clean the pipe can lead to improper sealing and potential leaks.
• Incorrect tool selection — Using the wrong press tool or jaw size can damage the fitting and compromise the connection.
• Over- or under-insertion of pipes — Marking the insertion depth helps avoid improper seating.
• Pressing an already pressed fitting — Press fittings should only be crimped once to maintain their integrity.
• Ignoring pressure testing — Always perform a pressure test to verify the system's reliability before completing the installation.
