## 7 Common Reasons Why O-Rings and Seals Fail

[O-rings](https://brennaninc.com/product-category/o-rings-and-seals/) are the most common hydraulic seal. They are used in [O-ring face seal](https://brennaninc.com/product-category/o-ring-face-seal-fittings/) and O-ring Boss fittings, as well as many other components. They are seated into a recess or channel, sealing [hydraulic system connections](https://brennaninc.com/) and preventing leaks around mating surfaces. Without them, it would be like a sprinkler system spraying hydraulic fluid or other chemicals. O-rings are essential to hydraulic systems, but they are not immune to failure.

O-rings can fail for a variety of reasons: improper material selection, incorrect seating or adverse environmental factors.
