06 Mar What Is an O-Ring?
If you’ve looked closely at the components that keep machines and systems running smoothly, you have probably seen an O-ring, a small but vital element. This unassuming ring is pivotal in various industry applications, helping industrial equipment operate efficiently and without leaks or damanges.
At I. B. Moore, O-rings and O-ring cords are one of our specialties, and we offer customers a broad selection of O-ring kits to meet their needs and expectations. You can rely on these accessories to withstand the elements and keep your business’s processes on track.
Circling back to the first question, though, what is an O-ring, and how does it work?
Understanding the O-ring Meaning
The term “O-ring” refers to the shape of this sealing device, but its importance goes beyond its physical form. These rings are engineered to withstand pressure, temperature variations, and chemical exposure. The O-ring meaning lies in its ability to provide a reliable, consistent seal, protecting the integrity of systems in different applications.
The Anatomy of an O-ring
An O-ring is a donut-shaped gasket made from materials like rubber or elastomer with a simple, effective design. Its circular cross-section allows it to fit securely into a groove, creating a seal between two or more working parts. The seal prevents liquids or gases from escaping, making O-rings essential components in a wide variety of mechanical systems.
O-ring Applications Across Industries
O-Rings for Aerospace
Precision is crucial in the aerospace industry, where O-rings are used in aircraft components like hydraulic systems and engines. O-rings maintain a tight seal even in extreme conditions, making them indispensable in ensuring the safety and functionality of aerospace equipment.
Automotive Industry O-Rings
When you turn the key in your car’s ignition, O-rings are quietly at work, sealing various components in the engine, fuel system, and air conditioning. They contribute to a vehicle’s overall reliability and efficiency, keeping it running as it should.
Or-Rings for Industrial Machinery
From pumps and valves to hydraulic systems, O-rings prevent leaks and maintain the efficiency of complex machinery. Their versatility and ability to work under fluctuating temperatures and pressure makes them suitable for a wide range of industrial applications.

The Importance of Material Selection
O-rings come in various materials, each chosen for its properties and suitability for unique conditions. I. B. Moore Company offers O-rings are made from:
- Buna: Made from nitrile for excellent abrasion and resistance to tearing
- EPDM: Recommended for brake systems for their elasticity and resistance to water, steam, acids, and many bases
- HNBR: Withstands temperatures to 300°; very effective against most oils
- Neoprene®: Used for freezing and cooling; withstands seawater, and temperatures to -67°F
- Silicone: Resists temperatures up to 450°F, ozone, weather, acids, and water
- Viton®: Withstands temperatures from -14°F to 400°, fungus, strong chemicals, oils, gas and acid
Ensuring Proper Installation and Maintenance
These donut-shaped gaskets provide a vital, reliable barrier against leaks and protect your investments against challenging conditions, but their effectiveness depends on proper installation and regular maintenance. They must be correctly positioned in their grooves, and we recommend regular inspections for wear and tear.
So the next time someone asks you, “What is an O-ring?” you’ll know the answer, which ones will suit your needs, and why proper installation and maintenance are essential.
