When you search for bonded seals, look no further than EORings.com. We offer a large variety of bonded seals in a variety of sizes and styles as well as materials (including aluminum, copper, and occasionally steel), so you're sure to find one that meets your applications needs. Bonded seals are washers that have a rubber lip on their inside diameter, and are used for high pressure applications where other methods of closing off are ineffective. They are available in a self-centralizing form to eliminate the offset of the closure and make installation easier. Our products also come in German and French metric sizes to cater to the needs of a wide variety of customers. Shop with EORings.com for affordable bonded seals.
