O-rings can become brittle over time, which leads to failure. If you’ve used your fittings for over a year, and you want to use them in a new build, It’s good practice to replace them, making sure they don’t leak on your shiny new components.
Or maybe you wish to change out your boring Black O-rings for the super cool Blue Silicone ones!
This set of 50, will keep you going for a long time!
