The combination of the sealing ring 30, the pressing washer 40 and the opening clamping sleeve part 50 can effectively solve the leakage problem in the connecting process of the air pipe 10, and the overall sealing effect is improved. Structurally, the gasket 30 is a core member of the gasket, and is made of a highly elastic and abrasion-resistant material to ensure excellent sealing performance during long-term use. The sealing ring 30 abuts against the end face of the second stage 207 to form a tight sealing barrier, which effectively prevents gas from leaking therefrom. Located behind the sealing ring 30 is a compression washer 40 which acts to provide sufficient compression to ensure a tight fit between the sealing ring 30 and the end face of the gas tube 10. The compression washer 40 is made of a material having a certain elasticity, and is capable of providing a sufficient compression force without causing excessive pressure to the air tube 10.
