EPDM O-rings are circular mechanical gaskets molded from ethylene propylene diene monomer rubber, widely used for static and dynamic sealing in various industrial applications.
They feature outstanding resistance to ozone, UV, weathering, water, steam and high temperatures, along with excellent flexibility and low compression set. Suitable for operating temperatures ranging from -50°C to +150°C, EPDM O-rings provide reliable sealing against liquids and gases, making them ideal for plumbing, automotive, water treatment, HVAC and outdoor equipment.
They can be customized in different sizes, hardness levels and colors to meet specific project requirements.
Certification and Specifications
All Rubber gasket must meet certain classes of ASTM C1619, depending on the specifications for a project. Generally, sanitary projects will require C1619 Class A (standard rubber) or B (oil-resistant rubber) and stormwater projects will reference C1619 Class C (standard) or D (oil-resistant).
Our factory has been ISO 9001 certified since 2005. In subsequent years, we have successively obtained ISO 14001, CE, EN 681 and SGS certifications, as well as other internationally recognized qualifications.
