The simple geometry is the main characteristic of an O-Ring which, in conjunction with proper elastomer selection results in a low cost, easy to use and efficient sealing system. Elastomeric materials, when compressed, react like a high viscosity fluid which transmits applied stress in every direction; consequently, the O-Ring serves as a barrier, blocking the leak paths between the sealing surfaces.
Technical sealing has been defined by DIN Standards as follows:
- "Static Seal" - The sealing action created between two mating surfaces with no leakage of liquid or minimal diffusion of gas.
- "Dynamic Seal" - The mating surfaces have relative movement with minimal leakage of liquid (usefuf to protect the sealing efficiency, acting as lubricant).
O-Rings offer several advantages over other sealing systems: simplicity of construction, standardized seal dimensions, wide selection of materials, suitability for both static and dynamic applications, standard dimensioning of glands, low cost due to high volume manufacturing.
Sealing is always achieved through a positive compression or squeezing action, resulting in a deformation of the O-Ring cross-section. The most important sealing characteristic of an O-Ring is its resistance to compression set or residual deformation.

Seal & Design’s Quality Mission is to be recognized as a world class supplier by manufacturing and shipping all parts to complete customer satisfaction. In achieving ISO/TS16949 certification in 2003, we commit to comply with the specified and expected needs of our customers on a daily basis.
Seal & Design’s vision inspection systems are designed to perform 100% inspection for circular rubber seals. These systems can inspect the dimensions, the height, the flatness, the concentricity, and the top and bottom surfaces for defects or irregularities, as well as sort the parts into different quality categories. Today, with the technology- leading industries, such as the automotive industry, requiring rubber seals with virtually no surface defects and precise dimensions for safety related, dynamic, and critical applications, Seal & Design is at the forefront satisfying this requirement.
