The extension tube design of the swivel funnel can be used easily when there are obstacles or narrow spaces at the filling port. The thread on the fixing clip is designed with an acute angle diameter to avoid slipping. 

     The filling fluid funnel tool has a rotatable extension rod and an adjustable threaded quick clamp, which can be easily inserted into different types of engine oil ports.

     The feature of high transparency allows you to observe the level of refueling well, and the filter screen is wrapped with metal to prevent deformation.
