O-Ring Material Characteristics and Application
The **rubber O-ring** is crucial for the sealing and sanitary performance. Aquinox O-rings use **imported rubber materials**, processed under standard vulcanization conditions and comply strictly with **GB/T 19228.3-2012**. Drinking water O-rings meet the **GB/T17219** standard, with **EU DVGW standard** options available. They resist hot water, ageing, and common drinking-water additives.
