The Comprehensive Guide to 22mm Rubber O-Rings in China
O-rings, simple yet crucial components, are ubiquitous in countless applications. This guide delves into the world of 22mm rubber O-rings, focusing on their availability and manufacturing in China. We’ll explore their technical features, different types, and key considerations when selecting the right O-ring for your needs. Sites like www.ebay.ca offer a vast marketplace for readily available O-rings, while specialized suppliers such as savvyrubber.com provide detailed information on material properties and manufacturing processes.
Understanding 22mm Rubber O-Rings
A 22mm rubber O-ring is a toroidal (donut-shaped) seal with an inner diameter of 22mm. Its primary function is to prevent leakage of fluids (liquids or gases) between two mating surfaces. The O-ring’s effectiveness relies on its ability to deform and create a tight seal when compressed within a groove. Many online marketplaces, including www.ebay.ca, list numerous 22mm O-rings from various suppliers. The material selection significantly impacts the O-ring’s performance and lifespan.
Key Technical Features of O-Rings
Several factors determine an O-ring’s suitability for a specific application. Key characteristics include its material, hardness, and dimensions. The inner diameter (ID), outer diameter (OD), and cross-sectional diameter (CS) must precisely match the intended groove. Hardness, measured on the Shore A scale, influences the O-ring’s ability to deform and maintain its seal under pressure. This information is readily available from suppliers like savvyrubber.com. Sites such as cn.element14.com and uk.farnell.com often provide detailed specifications for their O-ring offerings.
| Feature | Description | Importance |
|---|---|---|
| Material | The type of rubber used (e.g., Nitrile, Silicone, Viton) | Determines chemical resistance, temperature range, and overall performance. |
| Hardness (Shore A) | A measure of the rubber’s stiffness. | Affects sealing ability, compression set, and ease of installation. |
| ID (Inner Diameter) | The diameter of the hole in the O-ring. | Must match the groove diameter for proper fit and sealing. |
| OD (Outer Diameter) | The overall diameter of the O-ring. | Crucial for proper fit within the groove. |
| CS (Cross-Section) | The thickness of the O-ring’s cross-section. | Influences compression and sealing force. |
| Operating Temperature | The temperature range within which the O-ring maintains its properties. | Prevents material degradation and seal failure. |
| Chemical Resistance | The O-ring’s ability to withstand exposure to specific chemicals. | Essential for applications involving contact with oils, fuels, or other chemicals. |
Different Types of 22mm Rubber O-Rings
While the basic design remains consistent, variations exist in materials and applications. Choosing the right material is crucial. Savvyrubber.com offers a comprehensive guide to different rubber compounds, including NBR, FKM (Viton), and Silicone. Each offers unique properties.

FAQs
1. What is the difference between NBR and Viton O-rings?
NBR O-rings are cost-effective with good oil resistance but limited temperature range. Viton O-rings offer superior chemical and high-temperature resistance, making them suitable for demanding applications, but at a higher cost.
2. Where can I find 22mm rubber O-rings in China?
Numerous suppliers in China offer 22mm rubber O-rings. Online marketplaces like www.ebay.ca and specialized distributors such as cn.element14.com and uk.farnell.com offer a wide selection. Savvyrubber.com is a manufacturer specializing in custom O-ring production.
3. How do I determine the correct size for my application?
You need to know the inner diameter (ID) of the groove where the O-ring will be seated. The cross-sectional diameter (CS) is also critical. Consult engineering drawings or specifications to ensure a precise fit.
4. What is Shore A hardness, and why is it important?
Shore A hardness measures the rubber’s stiffness. A higher Shore A value indicates greater hardness. The appropriate hardness is crucial for maintaining a seal under pressure while ensuring ease of installation.
5. Are there FDA-compliant 22mm rubber O-rings?
Yes, many suppliers offer FDA-compliant silicone rubber O-rings, suitable for food contact and medical applications. Check the material specifications carefully to ensure compliance with relevant regulations.
