Advantages of Fittings
- **Easy Assembly**: Practical and convenient (**efficient installation in seconds**).
- **Quick Installation**: Saves hours of labour, ideal for large projects.
- **Safe and Approved**: Guaranteed system with reliable sealing.
- **Simplified Labour**: No need for specialised personnel (just a press tool).
- **Flameless Connection**: Enhances safety by eliminating the need for naked flames.
O-Ring Material Characteristics and Application
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 under controlled vulcanization conditions. They strictly comply with **GB/T 19228.3-2012**. O-rings for drinking water are fully in line with the **GB/T17219** standard; EU **DVGW** compliant options are also available. O-rings are resistant to hot water, ageing, and common drinking-water additives.
