**Title: Valve Sealing Ring and Flange Gasket: Don't Confuse Again

**Introduction:**

Valve sealing rings and flange gaskets are often mistaken for the same thing. In fact, there are significant differences between the two in terms of installation location, function, and replacement cycle. Correctly distinguishing them is the first step in ensuring pipeline safety and preventing leaks.

**Main text:**

**The valve sealing ring * * is installed inside the valve (such as at the valve disc and valve stem), and its main function is to cut off the flow of the medium when the valve is closed, achieving internal shut-off. It is usually made of high temperature resistant and corrosion-resistant elastic rubber material, which directly affects the opening and closing life and sealing level of the valve.

**The flange gasket is installed between the connecting end faces of two flanges and is a sealing component at the pipeline connection. It mainly prevents the medium from leaking out of the connection when the pipeline pressure fluctuates.

Simply put, the valve sealing ring pipe is "internally closed", and the flange gasket pipe is "leak proof at the interface".

In daily communication, many people are accustomed to collectively referring to the annular seals inside valves as "flange gaskets", which can easily cause confusion in technical selection and procurement. The materials, dimensions, and compression requirements of the two are different, and mixing or misusing them can pose serious safety hazards.

**We provide professional valve sealing rings and matching flange gasket solutions, supporting customization according to working conditions, helping you prevent running, emitting, dripping, and leaking from the source. **

**Conclusion:**

Although the seal is small, it is crucial for safety. Only by selecting and using correctly can the pipeline system operate stably for a long time. If you have any selection questions, please feel free to consult at any time.
