They are often used in automotive and plumbing applications. The video up top provides guidelines on how to take keep these rings in good condition.

This O-ring made of nitrile seals joints to stop fluid and gas leakages. The rings are typically constructed from a synthetic rubber compound that is impervious to oils and chemicals. Nitrile rubber is stronger over regular rubber. While it’s stronger than ordinary rubber, it has less flexibility. These rings are mostly made from silicone because it’s stronger and more resistant to acids, oils and ozone. But, they should not be mistaken for Viton O rings. Viton O rings can be used for applications that require higher temperatures as well as resistance to chemical.

The nitrile o-rings are defined by the colors they have. Here is a list of some colors along with their meanings:

Black (Oil and gas).

Blue (Metal Detectable).

Green (Air conditioning)

Rust Red (Silicone).

Clear (Urethane)

Nitrile o rings are affordable, have good resistance, and are easy to put in. Nitrile o rings are an excellent alternative in many different sectors.
