Understanding 1.25 Rubber O-Ring Specifications
The “1.25” in “1.25 rubber O-ring” typically refers to a dimension, either the inner diameter (ID) or outer diameter (OD), measured in inches or millimeters. Precise specifications always include both ID and OD, along with the cross-sectional diameter (CS). Accurate measurements are vital for a proper seal. Improper sizing can lead to leaks or damage to the equipment. Suppliers such as Home Depot and Zoro.com often provide detailed specifications to help with selection.
Technical Features of 1.25 Rubber O-Rings
Several technical features influence O-ring performance. These include material hardness (Shore A durometer), operating temperature range, and chemical resistance. The choice of material and hardness depends on the specific application and the environment. MISUMI, for example, provides a wide selection with varying technical parameters.
| Feature | Description |
|---|---|
| Inner Diameter (ID) | The diameter of the hole the O-ring seals. |
| Outer Diameter (OD) | The overall diameter of the O-ring. |
| Cross-Section (CS) | The diameter of the O-ring’s circular cross-section. |
| Durometer | A measure of the rubber’s hardness (Shore A scale). Higher numbers mean harder. |
| Operating Temp. | The temperature range within which the O-ring maintains its sealing properties. |
| Chemical Resistance | The O-ring’s ability to withstand exposure to various chemicals. |
Different Types of 1.25 Rubber O-Rings
Various rubber materials are used in O-ring manufacturing, each with unique properties. The selection depends on the application’s requirements. Lowe’s and Oringsandmore.com showcase the variety available.
| Material | Properties | Applications |
|---|---|---|
| Nitrile (Buna-N) | Good oil and fuel resistance, moderate temperature range. | Automotive, hydraulic systems, general industrial applications. |
| Ethylene Propylene (EPDM) | Excellent weather and ozone resistance, good chemical resistance. | Outdoor applications, chemical processing, potable water systems. |
| Silicone | High and low-temperature resistance, good flexibility. | High-temperature applications, aerospace, food and medical industries. |
| Viton (FKM) | Excellent chemical and temperature resistance, good for aggressive environments. | Chemical processing, high-temperature hydraulic systems. |
Choosing the Right 1.25 Rubber O-Ring
Selecting the appropriate O-ring involves careful consideration of several factors. These include the application’s pressure, temperature, and the fluids it will be exposed to. The chosen material must be compatible with the fluids. The correct ID and OD are critical for a secure and leak-proof seal. Oringsandmore.com provides detailed information on material selection.

FAQs
1. What is the difference between a 1.25-inch ID and a 1.25-inch OD O-ring?
The ID is the diameter of the hole the O-ring fits into, while the OD is the O-ring’s total diameter. A 1.25-inch ID O-ring seals a 1.25-inch hole, whereas a 1.25-inch OD O-ring has a total diameter of 1.25 inches.
2. How do I determine the correct size of a 1.25 rubber O-ring?
You need the inner diameter (ID) of the groove it will seal, and the cross-sectional diameter (CS). The OD is calculated from the ID and CS. Consult sizing charts or supplier specifications.
3. What is the typical material for a 1.25 rubber O-ring?
Nitrile (Buna-N) is a common material due to its cost-effectiveness and good resistance to oils and fuels. However, other materials like EPDM, silicone, and Viton (FKM) are used for specific applications.
4. What temperature range can a typical 1.25 rubber O-ring withstand?
The temperature range varies significantly based on the material. Nitrile typically performs well between -30°C and 100°C, while silicone can handle a much wider range, including higher temperatures.
5. Where can I find 1.25 rubber O-rings in China?
Numerous suppliers in China offer 1.25 rubber O-rings. Online marketplaces, industrial supply stores, and specialized O-ring manufacturers are all potential sources. Many international companies also ship to China.
