1. Leaking Compression Fittings
One of the most common problems with PEX Brass Copression Fittings is leakage. This can occur due to various reasons, such as overtightening or undertightening the fitting, using damaged or worn-out fittings, or misaligning the PEX pipe.
Solution:
To fix leaking compression fittings, follow these steps:
- Tighten the fitting: Check if the compression fitting is properly tightened. Use a wrench or pliers to tighten the fitting, but avoid overtightening.
- Replace damaged fittings: If the fitting is damaged, replace it with a new one.
- Insert the PEX pipe correctly: Make sure the PEX pipe is fully inserted into the fitting. Misalignment of the pipe can lead to leakage.
2. Fittings Slipping off the Pipe
Another issue that can happen with PEX Brass Copression Fittings is that they can slip off the pipe, causing leaks and water damage.
Solution:
To prevent fittings from slipping off the PEX pipe, do the following:
- Correctly size the fitting: Choose the correct size of fitting for the PEX pipe, as using a larger or smaller fitting can lead to slippage.
- Tighten the fitting: Ensure that the compression fitting is tightened correctly, and avoid overtightening.
- Use crimp rings or other securing devices: In addition to using PEX Brass Copression Fittings, consider using crimp rings or other securing devices to keep the fittings in place.

3. Fittings Getting Stuck
Sometimes PEX Brass Copression Fittings can get stuck when trying to connect or disconnect them.
Solution:
To remove stuck compression fittings, follow these steps:
- Loosen the fitting: Loosen the fitting with pliers or a wrench slowly, avoiding sudden movements.
- Use a lubricant: Apply a lubricant, such as PEX fitting lubricant, to loosen the fitting.
- Twist the fitting: Twist the fitting back and forth gently to help loosen it and remove it from the PEX pipe.
4. Fittings Not Fitting Properly
Another issue that can occur with PEX Brass Copression Fittings is that they do not fit correctly, resulting in a loose connection and leakage.
Solution:
To address fittings that do not fit properly, do the following:
- Check the size: Verify that you are using the correct size of fitting for the PEX pipe.
- Align the PEX pipe: Ensure that the PEX pipe is aligned correctly and fully inserted into the fitting.
- Replace the fitting: If the fitting is worn out or damaged, consider replacing it with a new one.
