Material Characteristics and Application of O-rings
The rubber **O-ring** for stainless steel press fittings is an important component which directly affects the sealing and sanitary performance of the entire system. **Aquinox O-rings** use imported rubber materials and are processed on automatic rubber vulcanizing machines under controlled vulcanization temperature and time. Aquinox strictly implements the performance standards in **GB/T 19228.3-2012**. The hygienic performance of the O-ring used for drinking water fully meets **GB/T17219**. We can also provide O-rings that meet the **EU DVGW standard**. O-rings are resistant to hot water, ageing, and the additives commonly used in drinking water. Different types are available depending on application.
