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.
