Applications

EPDM O Rings are widely used for sealing hot water, steam, cooling water, and outdoor environments. Thanks to the excellent ozone resistance, weather resistance, UV resistance, and heat resistance of EPDM rubber, these O Rings deliver stable performance in HVAC systems, plumbing, automotive cooling circuits, water treatment equipment, and industrial sealing applications.

EPDM O Rings are especially suitable for polar fluid environments, including water, steam, glycol-based brake fluid, and mild acids or alkalis.

Note: EPDM O Rings are not recommended for mineral oil, fuel, or petroleum-based oils.

Frequently Asked Questions

1. Can you produce customized goods?

Yes. The size, diameter, and length can be produced as per client requirements.

2. Can you print words on products as per client requirement?

Yes. We can make labels according to your exact requirements.

3. Can you do business via Ali Online Transaction?

Yes, we can make the deal through AOT.

4. Do you accept OEM?

Yes, both OEM and ODM are acceptable.

5. How can you guarantee quality or provide a warranty?

If any quality problems occur during use, all products can be returned or handled according to the consumer's requests.

6. What are the critical items to consider when selecting materials?

Even if the size is very consistent, the seal may have no resistance to certain fluids and temperatures, which can cause swelling, stiffening, shortened life, and leakage. Therefore, make sure to confirm fluid and temperature conditions in advance.

7. What storage methods should be observed for rubber seals?

Keep in a place without direct sunlight. UV and heat will accelerate the aging of the rubber.
Keep in ventilated, low-humidity places, away from moisture and mildew.
Avoid placing near high-temperature heat sources. Heating can accelerate the aging of the rubber.
Avoid hanging on hooks or metal lines, or wearing them with a belt hanging. Avoid stressing the rubber parts.
Keep fully packaged to prevent scratches or foreign matter adhesion.
