Technical Features of 15mm O-Rings
The effectiveness of a 15mm O-ring depends heavily on its technical specifications. These specifications ensure the O-ring provides a reliable seal under various conditions. Key features include dimensions, material hardness, tensile strength, and compression set. Precise measurements are essential for a proper fit, preventing leaks. The material’s hardness influences its ability to withstand pressure and deformation. Tensile strength and compression set are crucial indicators of durability and longevity. Suppliers like www.svks-rubberseal.com emphasize these aspects in their product descriptions.
| Feature | Description | Importance |
|---|---|---|
| Outer Diameter | The overall diameter of the O-ring. | Determines the size of the groove and compatibility with mating parts. |
| Inner Diameter | The diameter of the hole in the center of the O-ring. | Determines the size of the groove and compatibility with mating parts. |
| Cross-Section | The thickness of the O-ring’s circular cross-section. | Influences the sealing force and ability to withstand pressure. |
| Shore A Hardness | A measure of the material’s resistance to indentation. | Determines the O-ring’s ability to withstand compression and maintain its shape. |
| Tensile Strength | The maximum stress a material can withstand before breaking. | Indicates the material’s resistance to tearing and stretching. |
| Elongation at Break | The percentage of elongation a material undergoes before breaking. | Indicates the material’s flexibility and resistance to deformation. |
| Compression Set | The permanent deformation after being compressed for a specific time and temperature. | Measures the O-ring’s ability to recover its shape after compression. |
Different Types of 15mm O-Rings
15mm O-rings are available in various materials, each offering unique properties suited to different applications. The choice of material depends on factors like temperature, chemical exposure, and cost. Websites like www.fobrubber.store offer detailed information on the properties of different elastomers.

FAQs
1. What is the difference between NBR and FKM O-rings?
NBR O-rings are cost-effective and resist oils and fuels. FKM O-rings are more expensive but offer superior resistance to high temperatures and a wider range of chemicals.
2. How do I determine the correct size of a 15mm O-ring?
The “15mm” likely refers to the inner diameter. You need to measure the groove’s diameter and cross-section to choose the correct size for a proper fit.
3. What are the common quality testing methods for O-rings?
Common methods include dimensional inspection, visual inspection, hardness testing, compression set testing, tensile strength and elongation testing, and chemical compatibility testing.
4. What are the advantages of sourcing O-rings from China?
China offers competitive pricing and large production capacity. However, careful supplier selection and quality control are crucial.
5. How can I ensure the quality of 15mm O-rings sourced from China?
Request samples for testing, verify supplier adherence to ISO 9001, and consider using third-party inspection services before final payment.
