Description
Stainless Steel Pipe Bridge with Plain End
Stainless Steel Pipe Bridge with Plain End is, as its name implies, a stainless steel pipe component with a “bridge” configuration and plain-end design. It is mainly used for connecting, redirecting, or transitioning between different pipelines in fluid or gas transmission systems, which enables more efficient pipe routing in confined spaces and reduces the need for additional elbows. Its key features include a smooth flow path and ease of connection, thereby enhancing installation efficiency and aesthetics. Given the inherent advantages of stainless steel—such as **corrosion resistance**, **high strength**, and **long service life**—this product is widely applied in residential, commercial, and industrial piping systems including water supply and drainage, HVAC, and gas pipelines.

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 use automatic rubber vulcanizing machine processed and produced through standard 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 is full in line with the **GB/T17219** standard. Besides, we can also provide O-rings that meet the **EU DVGW standard**. O-ring resistant to hot water, ageing and the additives commonly used in drinking water. There are different kinds of O-rings depending on its application.
