Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.

O-Rings

FOREVER SEALS is a leading O-ring manufacturer specializes in creating high-performance O-rings, selecting materials such as NBR, FKM, silicone, EPDM, ACM, AFLAS, FFKM and FEP, giving the product oil resistance, chemical resistance and wide temperature range (-50°C to 320°C) characteristics.

 

For the automotive industry, we recommend NBR material, which has excellent oil resistance and a working range of -30°C to 120°C, which is perfectly adapted to engine sealing needs. For high-temperature and highly corrosive occasions such as chemical pipelines, FKM material can be selected, which has a high temperature resistance of 200°C and strong chemical corrosion resistance. Silicone material, because of its non-toxic, odorless and high elasticity, is an ideal choice for sanitary sealing of food machinery.

 

We provide a comprehensive selection of materials and sizes to ensure that each O-ring seal can accurately meet various static and dynamic sealing needs from automobiles to aviation, petroleum and even chemical pipelines. FOREVER SEALS, your all-round o-ring seal supplier and sealing solution expert.
