Material Characteristics and Application of O-Rings
The rubber O-ring for stainless steel press fittings directly affects sealing and sanitary performance. Aquinox O-rings use **imported rubber materials**, processed under controlled vulcanization conditions and comply with **GB/T 19228.3-2012**. Drinking water O-rings comply with **GB/T17219**; **DVGW-compliant** options are available. They resist hot water, ageing, and common drinking-water additives, making them reliable for various applications like water treatment, oil & gas, and food processing.
