A Comprehensive Guide to Red Rubber O-Rings in China
Red rubber O-rings are essential sealing components used across diverse industries. China is a major producer and exporter of these versatile parts, offering a wide range of options to global buyers. This guide explores the world of red rubber O-rings sourced from China, delving into their technical specifications, material variations, and key suppliers. Understanding these aspects is crucial for selecting the right O-ring for specific applications.
Understanding Red Rubber O-Ring Specifications
Red rubber O-rings, often found on TradeWheel (www.tradewheel.com) and Kingtom Rubber (www.kingtomrubber.com), are circular seals with a cross-section resembling a torus. Their primary function is to prevent leakage between two mating surfaces. Several critical parameters define their performance and suitability. These include the inner diameter (ID), outer diameter (OD), cross-sectional diameter (CS), and material hardness (Shore A). The material’s chemical resistance and temperature range are equally important considerations.
The color red is often chosen for its visibility and to indicate a specific material or application. It’s important to confirm the material type and specifications with the supplier. Many manufacturers, like Xiamen Xlong Seal Co., Ltd. (featured on www.tradewheel.com), offer custom-colored O-rings to meet specific branding or identification requirements.
Technical Features Comparison Table
| Feature | Description |
|---|---|
| Inner Diameter (ID) | The inside diameter of the O-ring. Determines the size of the bore it seals. |
| Outer Diameter (OD) | The outside diameter of the O-ring. Influences the groove size needed. |
| Cross-Section (CS) | The thickness of the O-ring’s cross-section. Affects compression and sealing. |
| Shore A Hardness | A measure of the material’s stiffness. Higher Shore A means greater hardness. |
| Tensile Strength | The material’s resistance to stretching or tearing. |
| Elongation | The material’s ability to stretch before breaking. |
| Temperature Range | The operational temperature range of the material. |
| Chemical Resistance | The material’s resistance to specific chemicals or fluids. |
Types of Red Rubber O-Rings and Their Differences
Various rubber materials are used to manufacture red O-rings, each possessing unique properties. The choice depends heavily on the application’s environmental conditions and required performance. Suppliers like SWKS Seal (www.svks-rubberseal.com) and Kaxite Sealing (www.seal-china.com) offer a wide range of materials.
Material Comparison Table
| Material | Temperature Range (°C) | Chemical Resistance | Hardness (Shore A) | Applications |
|---|---|---|---|---|
| Nitrile (NBR) | -30 to +100 | Oils, fuels, water | 50-90 | Automotive, hydraulic systems |
| Silicone (VMQ) | -60 to +200 | Ozone, UV, some chemicals | 30-80 | High-temperature applications, food contact |
| EPDM | -40 to +150 | Ozone, heat, water, some chemicals | 40-70 | Automotive weather stripping, water systems |
| Viton (FKM) | -20 to +250 | Wide range of chemicals, high temperatures | 60-90 | Chemical processing, aerospace, high-pressure seals |
