Material condition and medium characteristics of Y-type sealing ring

Y-type sealing ring is a commonly used sealing element, and its cross section shape is Y. According to the actual use and medium characteristics, Y-type sealing rings are usually made of the following materials:

Fluoroelastomer:

Fluorine rubber is an excellent sealing material, with high temperature resistance, chemical corrosion resistance and good elastic recovery performance. It is suitable for sealing applications in a range of corrosive media and high temperature environments. Fluororubbers are excellent in heat resistance and chemical stability, and are suitable for concentrated acids, concentrated alkalis, solvents and some organic media.

Nitrile Rubber:

Nitrile butadiene rubber is an oil-resistant, wear-resistant synthetic elastic material suitable for many liquid and gas sealing applications. It has good tolerance to petroleum substances such as fuel oil, lubricating oil and diesel oil. Nitrile rubber has a lower cost and can be used over a wide temperature range.

Silicone Rubber:

Silica gel is a kind of synthetic elastic material with excellent high temperature resistance, aging resistance and deformation resistance. It has excellent performance in high temperature resistance, oxidation and electrical insulation. Silica gel is suitable for sealing applications in high temperature environment, and has good tolerance to high temperature steam, hot oil and other media.

Chloroprene Rubber:

Neoprene rubber is an organic synthetic rubber material with good oil resistance and wear resistance. It is widely used in the field of mechanical sealing, especially for the sealing of lubricating oil, fuel oil and other media.

The material choice of Y-type sealing ring depends on the operating temperature, pressure, chemical properties of the medium and other factors. The compatibility between the sealing ring and the medium must be considered when selecting the material to ensure good sealing and long service life. It is recommended to refer to the technical data and recommendations provided by the supplier when selecting the material.
