1623634: O-RING

**Product Description: O-Rings** **General Description:** - **Shape and Function**: O-Rings are toroidal elastomeric sealing devices with a circular cross-section designed to create a seal by being compressed between two mating surfaces. They effectively prevent the passage of fluids or gases in both static and dynamic situations. - **Materials**: Made from a variety of elastomers such as NBR (Nitrile-Butadiene Rubber), FKM (Fluorocarbon), and VMQ (Silicone). Material selection depends on application requirements like temperature resistance and chemical compatibility. **Specifications:** - **Dimensional Standards**: Available in standardized sizes such as AS568 (inch sizes) and ISO 3601 (metric sizes). Dimensions are defined by the inside diameter (d1) and cross-section (d2). - **Size Range**: Cross-sections range from approximately 0.35 mm to 40 mm, with inside diameters up to 5,000 mm or more. - **Hardness**: Typically measured on the Shore A scale, with options ranging from 10 to 90 durometer to suit various compression and sealing needs. **Key Features:** - **Versatility**: Suitable for various industries, including aerospace, automotive, food processing, and general engineering. - **Sealing Capabilities**: Can handle pressures up to 5,000 psi (34 MPa) depending on material and design. Their flexible nature assists in accommodating surface irregularities for effective sealing. - **Compact Design**: Minimal hardware modifications are required due to its straightforward groove design. **Applications:** - **Static Sealing**: Used in applications like flanges, covers, pipes, and cylinders where there is no relative motion between parts. - **Dynamic Sealing**: Suited for moderate conditions in applications such as reciprocating pistons or slowly rotating shafts. - **Specialized Uses**: Encapsulated O-Rings with PTFE coatings are ideal for aggressive media and high-temperature environments, with FDA-compliant options available for food and medical applications. **Advantages:** - **Cost-effective**: Easy to produce and use, making O-Rings one of the most popular sealing solutions. - **Reliable Performance**: Provide dependable sealing across a wide temperature range and resist various chemicals based on material. This product is highly adaptable for diverse engineering needs due to its simplicity, reliability, and availability in numerous configurations.
