O-Ring Material Characteristics and Application
The rubber **O-ring** is critical to the sealing and hygienic performance of stainless steel press fittings. Aquinox O-rings use **imported rubber compounds** and automated vulcanization to meet strict production controls, complying with **GB/T 19228.3-2012**. Options suitable for drinking water comply with **GB/T 17219**, and **EU DVGW** compliant options are also available. These O-rings resist hot water, ageing, and common drinking-water additives.
