By focusing on the quality of the press fittings and the specifications of the pressing tool, you can significantly reduce the risk of leaks in press fittings.
Quality of Press Fittings
- Material Integrity: Ensure that the press fittings are made from high-quality materials (e.g., copper, stainless steel) that are resistant to corrosion and wear.
- Seal Design: Look for fittings with reliable sealing mechanisms, such as O-rings or other sealing technologies, designed to create a tight seal when pressed.
- Compatibility: Verify that the fittings are compatible with the type of pipe being used, including material and size specifications.
Press Tool Specifications
- Tool Calibration: Ensure that the pressing tool is calibrated according to the manufacturer's specifications to apply the correct amount of pressure.
- Tool Condition: Regularly inspect and maintain the pressing tool to ensure it is in good working condition, free from wear or damage that could affect performance.
- Pressing Technique: Use the tool according to the manufacturer's guidelines, ensuring proper placement and even pressure application during the pressing process.
