The Comprehensive Guide to 35mm Rubber O-Rings
35mm rubber O-rings are versatile sealing components used across various industries. Their effectiveness stems from their ability to create a tight seal between surfaces, preventing leakage of liquids, gases, or other substances. Understanding their technical features, material variations, and quality control is crucial for proper selection and application. This guide explores these aspects in detail.
Comprehensive Insights into 35mm Rubber O-Rings
O-rings are manufactured using various elastomers like nitrile rubber (NBR), silicone (VMQ), fluorocarbon rubber (FKM), and ethylene propylene diene monomer (EPDM). The choice depends on the specific application’s needs, considering factors such as temperature, chemical resistance, and pressure. Websites like www.fobrubber.store provide detailed information on these materials and their applications. Manufacturers like Haisun Rubber, found at www.orings-china.com, offer custom O-ring solutions to meet precise specifications.
The manufacturing process involves molding the chosen elastomer into a toroidal shape with precise dimensions. This ensures consistent sealing performance. High-precision manufacturing is emphasized by companies like IKSonic at www.iksonic.com, highlighting their ability to achieve tight tolerances. The O-ring’s circular cross-section creates a seal by compressing against mating surfaces. This compression is crucial for effective sealing and is carefully controlled during manufacturing.
O-rings are widely used in various industries. Mechanical engineering utilizes them in hydraulic and pneumatic systems. The automotive industry employs them in engines, transmissions, and braking systems. Medical device manufacturers incorporate them in equipment requiring sterile conditions. Consumer electronics use O-rings for water resistance in devices such as smartphones. The aerospace industry relies on them for high-pressure applications. Amazon, www.amazon.co.uk, lists numerous O-ring products for diverse applications.

FAQs
1. What is the difference between the inner diameter (ID), outer diameter (OD), and cross-section (CS) of a 35mm O-ring?
The ID is the diameter of the hole in the O-ring. The OD is the diameter of the O-ring’s outer edge. The CS is the thickness of the O-ring’s cross-section. A 35mm O-ring typically refers to its ID. Accurate measurements are critical for proper sealing.
2. How do I choose the right material for my 35mm rubber O-ring?
Material selection depends on the application’s operating conditions. NBR is suitable for general applications, EPDM for outdoor and water systems, FKM for harsh chemical and high-temperature applications, and silicone for medical and food-grade applications. Consider the specific chemical and temperature demands of your application.
3. What are the common quality testing methods for 35mm rubber O-rings?
Testing includes dimensional accuracy using calipers, material property testing (hardness, tensile strength, compression set), visual inspection, leak testing, and chemical resistance testing. These tests ensure the O-ring meets required specifications and performs reliably.
4. Where can I find reliable suppliers of 35mm rubber O-rings in China?
Many reliable suppliers exist. Websites like www.orings-china.com and www.iksonic.com list Chinese manufacturers. Online B2B platforms also offer numerous options. Verify supplier credentials and request samples before committing to a large order.
