O-Rings

Hanna Rubber offers one of the industry's largest inventory of O-rings including every standard AS-568 size. We also carry a wide variety of metrics and non-standard sizes. Most likely the size and compound you require is in stock. Our O-ring inventory is constantly restocked to assure immediate delivery.

O-rings are used for sealing liquids or gases against leakage and loss. Most O-rings are elastomers, although rings are also available in hollow and solid metals, plastics and PTFE.

When properly designed into an appropriate 'gland', an O-ring can seal against a wide range of pressures and temperatures, cost-effectively and with minimal maintenance. It is critical when designing an O-ring into an application to consider the gland size/fit, chemical compatibility of the fluid or gas on the seal, compression forces, temperature variations, pressure requirements, and any other outstanding issues that might adversely effect the seal.
