Durable EPDM O - Rings 16 20 26 32 for Various Sealing Applications

Product Material & Size​

• High - Quality EPDM Rubber: Made from ethylene propylene diene monomer (EPDM), these O - rings offer exceptional resistance to water, heat (up to 150°C), ozone, and chemicals. They remain flexible in temperatures ranging from - 40°C to 150°C, ensuring long - term durability without hardening or cracking.​

• Precise Sizing: The 5321 series includes 16mm, 20mm, 26mm, and 32mm inner diameters, matching standard sealing grooves. Consistent thickness and roundness guarantee a tight fit, creating reliable seals in various equipment.​

Use Scenarios​

• Plumbing Systems: 16mm and 20mm O - rings seal pipe connections, valves, and faucets in homes and commercial buildings, preventing water leaks in bathrooms, kitchens, and heating systems.​

• Industrial Machinery: 26mm and 32mm sizes suit pumps, compressors, and hydraulic equipment, sealing fluid or gas lines to maintain pressure and prevent contamination.​

• Automotive & Appliances: Ideal for car engines, washing machines, and refrigerators, where they resist heat and moisture to ensure appliance efficiency and longevity.​

How to Use​

1. Preparation: Select the correct size (16/20/26/32mm) matching the sealing groove. Ensure the groove and O - ring are clean, free of debris, oil, or sharp edges that could damage the rubber.​

2. Installation: Stretch the O - ring gently and place it into the groove, ensuring it lies flat without twists or overlaps. Press the mating surfaces together to compress the O - ring, creating a tight seal. Avoid over - stretching to prevent premature wear.​

3. Maintenance: Inspect periodically for cracks, hardening, or wear. Replace if damaged to maintain sealing performance. Store unused O - rings in a cool, dry place away from direct sunlight and chemicals.​
