Ensuring a leak-free connection with brass push-in fittings involves several key steps to be executed carefully:
Proper Tube Preparation: Ensure that the tube is cut cleanly and squarely using a tube cutter. Any uneven cuts or rough edges can compromise the seal. Use a deburring tool to remove any sharp edges or burrs from the cut end of the tubing.
Correct Sizing: Verify that the tubing size matches the fitting size for a proper fit. Using the correct size is essential to create a tight and secure seal.
Cleanliness: Keep both the fitting and the tubing clean before assembly. Any dirt, debris, or contaminants on the surfaces can cause leaks.
Insertion: Push the tubing into the fitting until it reaches the tube stop. Ensure that it's inserted fully to the appropriate depth without forcing it excessively, as this might damage the fitting or the tube.
Visual Inspection: Verify that the tubing is fully inserted into the fitting by checking the insertion depth indicator (if available). A visual inspection should confirm that the tubing is properly seated.
Locking Mechanism: Many brass push-in fittings come with a locking mechanism that secures the tube in place. Ensure that this mechanism is engaged or locked after inserting the tube to maintain a leak-free connection.
Pressure Test: Perform a pressure test on the assembled fittings to ensure the connection is leak-free. Apply the system's operating pressure and inspect for any leaks.
Following these steps diligently helps to establish a secure and leak-free connection with brass push-in fittings. If leaks persist, recheck the installation process and examine the fittings and tubing for any defects or irregularities that might compromise the seal.
