The invention provides a low-permeability oil filling pipe assembly. The low-permeability oil filling pipe assembly comprises a metal main pipe, a low-permeability nylon pipe and a quick inserting part. An oil filling port is formed in one end of the metal main pipe, a threaded metal part used for being connected with an oil filling port cover is fixed to the oil filling port, a connecting part used for being connected with an automobile body is fixed to the end, close to the oil filling port, of the metal main pipe, a metal circulating pipe is connected to the metal main pipe, and the metal circulating pipe is communicated with the metal main pipe. One end of the low-permeability nylon pipe sleeves the other end of the metal main pipe, and the low-permeability nylon pipe is in interference fit with the metal main pipe. The quick inserting part is used for being connected with an oil tank, and the quick inserting part is connected with the other end of the low-permeability nylon pipe in a sealed manner. Through combination of the metal main pipe and the low-permeability nylon pipe, light weight of the oil filling pipe can be achieved, and meanwhile the problems of aging and leakage of rubber parts of the oil filling pipe are solved.

    本发明提供一种低渗透加油管总成,其包括有:金属主管、低渗透尼龙管和快插件。所述金属主管的一端为加油口,所述加油口固定有用于连接加油口盖的螺纹金属件,所述金属主管中靠近所述加油口的一端上固定有用于连接车身的连接件,所述金属主管上连接有金属循环管,所述金属循环管与所述金属主管相连通。所述低渗透尼龙管的一端套于所述金属主管的另一端,所述低渗透尼龙管与所述金属主管过盈配合。所述快插件用于连接油箱,所述快插件与所述低渗透尼龙管的另一端密封连接。通过金属主管和低渗透尼龙管相结合能够实现加油管的轻量化,同时避免加油管出现的橡胶件老化与泄露的问题。
