AI Technical Summary
Existing rubber gaskets wear and age after long-term use due to the compressive load of nuts, which in turn leads to loose and unreliable connections.
By placing the gasket body between the limiting ring and the support ring, and utilizing the design of the limiting groove, limiting teeth and protrusions, excessive friction and compression of the nut on the gasket are avoided. Combined with the deformation and reverse elastic force of the support ring, the connection is strengthened and contamination is prevented.
It effectively avoids excessive wear and aging of the gasket, enhances the reliability and firmness of the connection, reduces the loosening of the nut, and improves the overall stability of the connector.
