At A2ZSeals, we carry an impressive selection of o-rings in a variety of materials and sizes. An O-ring is basically a solid-rubber seal, which is shaped like a torus or doughnut. It is suitable for numerous sealing uses including reciprocal, static, dynamic, and oscillating applications at pressure and low speed. The extrusion resistance of an o-ring is increased with the addition of a backup ring during elevated operating pressure environments.
Viton, NBR, PTFE, and Silicone are some of the most common materials of o-rings. The techniques and sizes of o-rings are rapidly growing. If you require special sizes or quality, contact us without any hesitation. We have stock of NOK, Parker, and various other brands. O Ring Boxes are also available IN TAIWAN MAKE, ITALY, EUROPEAN, AND OTHERS.
What is an O-Ring?
Generally, manufacturers mold an O-ring from an elastomer to create a torus, or doughnut-shaped ring. Manufacturers can also make O-rings from PTFE and other thermoplastic materials, as well as metals, both hollow and solid. However, this handbook exclusively covers elastomeric O-rings.
People primarily use O-rings for sealing. This section describes the various types of O-ring seals under the “Scope of O-Ring Use.” People also use O-rings as light-duty, mechanical drive belts. You can find more information, including design criteria for O-ring drive belts and their application, in O-rings applications.
An O-ring seal is used to prevent the loss of a fluid or gas. The seal assembly consists of an elastomer O-rings and a gland. An O-rings is a circular cross-section ring molded from rubber
The gland — usually cut into metal or another rigid material — contains and supports the O-rings. The combination of these two elements; O-rings and gland — constitute the classic O-ring seal assembly.
Sometimes it is used as a Gasket.
Introduction
An O ring, also known as a seal ring or toric joint, is a simple yet essential component used in various industries. It plays a critical role in sealing applications, preventing leaks and ensuring the efficient operation of hydraulic systems, machinery, and more. In this guide, we will delve into the world of O rings, exploring their usage, function, strength, materials, types, tensile strength, and unique selling points (USP).
Usage of O Rings
O rings are used in a wide range of applications across industries such as automotive, aerospace, manufacturing, and hydraulic systems. Their primary purpose is to create a seal between two or more parts, preventing the escape of fluids or gases. Some common uses include:
- Seal Kits
- Oil Seal Kits
- Hydraulic Cylinder Seals & Seal Kit
- Oil Seals
- Shaft Seals
- Hub Seals
- Cassette Seals
- Gear Box Seals
- Pump Seals & Kits
- O Rings Box & Kits
- Floating Seals
- Engine Oil Seals
- PTFE Seals
- Motor Seals & Kits
- HUB Kit
The function of O Rings
The primary function of an O ring is to create a tight, reliable seal between mating surfaces. When compressed between two parts, the O ring fills the gap and prevents the passage of liquids or gases. This sealing action is crucial to:
- Prevent leaks
- Reduce friction and wear
- Isolate contaminants
- Maintain system integrity
Strength of O Rings
O rings are designed to withstand various mechanical and environmental stresses. Their strength is essential to ensure the reliability of the seals they create. Factors that contribute to the strength of O rings include:
- Material selection
- Size and dimensions
- Compression and temperature tolerance
Materials Used in O Rings
The choice of materials for O rings depends on the specific application and the operating conditions. Common materials used in O ring manufacturing include:
- Nitrile rubber (NBR)
- Fluoroelastomer (FKM or Viton)
- Silicone rubber (VMQ)
- EPDM rubber
- Polytetrafluoroethylene (PTFE)
- SILICON
Each material has its unique properties, making it suitable for different environments and fluids.
Types of O Rings
O rings come in various types to accommodate diverse applications. The choice of O ring type depends on factors such as temperature, pressure, and chemical compatibility. Some common types include:
- Standard O rings
- Quad rings
- Back-up rings
- O ring cord
- Custom O rings
Tensile Strength of O Rings
The tensile strength of an O ring is a critical parameter that measures its ability to withstand stretching or pulling forces. It is crucial to ensure that the O ring remains intact under various conditions. Tensile strength is typically specified in pounds per square inch (psi) or megapascals (MPa) and varies depending on the material and size of the O ring.
Unique Selling Points (USP) of O Rings
O rings offer several unique selling points that make them indispensable in many industries:
- Cost-effective sealing solutions
- Wide range of materials for compatibility
- Highly customizable for specific applications
- Reliable performance in extreme conditions
- Easy installation and maintenance
- Reduced risk of leakage and system failures
