How to ensure the sealing performance of the pressure gauge connector in design?

In terms of structural design, the pressure gauge connector usually adopts a specific interface form, such as a 24° cone design. This cone design enables the connector to form a tight fit with the matching parts when connected, thereby effectively reducing the possibility of leakage. The precise control of the cone angle is one of the key factors to ensure the sealing performance, which ensures that the contact area between the connector and the interface is maximized, thereby improving the sealing effect.

Secondly, the pressure gauge connector will be equipped with special seals, such as O-ring seals. This seal is usually made of materials with good elasticity and chemical corrosion resistance, such as rubber or fluororubber. The O-ring is installed in a specific position of the connector. When the connector is docked with the interface, the O-ring will be squeezed and deformed, thereby filling the small gap between the connector and the interface, forming a reliable sealing barrier. This design can not only effectively prevent medium leakage, but also resist the influence of external pressure and temperature changes on sealing performance to a certain extent.

In addition to O-ring seals, the female end of some pressure gauge connectors will also be equipped with steel or copper gaskets. These gaskets usually have a flat surface and a certain degree of elasticity, which can provide an additional sealing layer between the connector and the interface. When the connector is tightened, the gasket will be compressed and deformed, so that it fits tightly between the connector and the interface, further enhancing the sealing performance.

In addition, the manufacturing materials and processing technology of the pressure gauge connector will also have an important impact on its sealing performance. High-quality materials and precise processing technology can ensure the dimensional accuracy and surface quality of the connector, thereby reducing sealing problems caused by manufacturing errors. At the same time, some advanced surface treatment technologies, such as sandblasting and polishing, can also improve the surface finish and corrosion resistance of the connector, further extending its service life and sealing performance.
