**Product Overview:**
Our rubber sealing O-ring series is designed to meet a wide range of industrial needs, offering reliable performance in various environments. These O-rings are commonly used for shower head sealing, but they also serve critical functions in automotive, hydraulic, and mechanical systems.
We maintain a large inventory of O-rings made from materials such as NBR, HNBR, Viton, EPDM, and Silicone, as well as special grades tailored for demanding applications in the petrochemical, gas, water, and food industries. Our standard sizes comply with international standards like AS568, DIN 3771, BS1806, BS4518, and ISO3601.
**Product Description:**
EPDM O-rings are particularly suited for applications involving water and steam due to their excellent resistance to weathering and ozone. They are ideal for use in shower heads, valves, and other sealing applications where durability and flexibility are essential.
In designing an O-ring seal, it's crucial to choose the right compound based on the application. The selected material must withstand the fluid being sealed, resist extrusion under pressure, and maintain physical properties across a wide temperature range. For dynamic applications, the material should also offer good toughness and abrasion resistance to ensure long-lasting performance.
