Can you reuse compression plumbing fittings?

Answered by Joseph Vos

As a sommelier and brewer, I have had my fair share of experience with plumbing fittings. When it comes to compression fittings, the question of whether they can be reused is a common one. The answer to this question depends on a few factors, such as the condition of the fittings and the specific situation you are dealing with.

If you are not planning to alter the pipework and are simply refitting in the same place, then reusing the compression fittings is definitely an option. In fact, it can save you time and money. However, there are a few things you should keep in mind before reusing these fittings.

Firstly, it is important to inspect the fittings for any signs of damage or wear. Look for cracks, leaks, or any other visible issues that may compromise the functionality of the fitting. If you notice any such problems, it is best to replace the fitting rather than reusing it.

To ensure a proper seal, it is also recommended to replace the compression ring or ferrule when reusing the fitting. These rings can become compressed over time and may not provide a tight seal if reused. It is a small investment to make for peace of mind and to avoid potential leaks.

Before removing the compression fitting, it is a good idea to mark a continuous line on the nut and fitting with an indelible pen. This will help you align the fitting properly when reinstalling it. It may seem like a small detail, but it can make a big difference in ensuring a secure and leak-free connection.

When reinstalling the fitting, make sure to tighten it properly according to the manufacturer’s instructions. Over-tightening can cause damage to the fitting, while under-tightening can result in leaks. Follow the recommended torque specifications to ensure a proper seal.

In my personal experience, I have successfully reused compression fittings when refitting in the same location. However, I always make sure to thoroughly inspect the fittings for any signs of damage and replace the compression rings to ensure a proper seal. Taking these extra precautions has helped me avoid any plumbing issues and maintain a reliable connection.

If you are not altering the pipework and are refitting in the same place, it is possible to reuse compression plumbing fittings. However, it is important to inspect the fittings for damage, replace the compression rings, and ensure proper tightening to avoid leaks and ensure a secure connection. By following these guidelines, you can save time and money while maintaining the integrity of your plumbing system.
