To use a copper press fit, you generally insert the copper pipe into the fitting up to the depth stop, mark the insertion depth, and then use a specialized press tool to crimp the fitting onto the pipe, creating a secure, permanent connection.
Here's a more detailed breakdown:
- Preparation is Key: Ensure the copper pipe is clean, deburred, and free of any imperfections. This is crucial for a proper seal.
- Insertion and Depth Marking: Insert the copper pipe into the press fitting until it reaches the depth stop within the fitting. Then, use a marker to create a line on the pipe where the fitting ends. This ensures the connection maintains the correct depth during the pressing process.
- Pressing the Fitting: Select the correct size pressing jaws for your press tool that matches the size of the copper press fitting. Position the jaws around the fitting. Activate the press tool to crimp the fitting tightly onto the copper pipe. The press tool creates a mechanically strong and leak-proof connection.
- Inspection: After pressing, visually inspect the connection. Most press fittings have a visual indicator, such as a dimple or a gap that closes when the fitting is properly pressed. Ensure this indicator shows a complete press.
Key Considerations:
- Tool Compatibility: Use only press tools and jaws specifically designed for the type and size of press fitting you are using.
- Fitting Selection: Choose the correct fitting material (e.g., copper, bronze) appropriate for the application.
- Pressure Rating: Ensure the press fittings have a pressure rating suitable for the system in which they will be used.
- Manufacturer's Instructions: Always consult and follow the manufacturer's specific instructions for the press fitting system you are using, as procedures and specifications can vary.
