Provided is a diesel exhaust fluid (DEF) sensor adapter. The sensor adapter may include two chambers. The first chamber may include a tortuous pathway for fluid and/or air flow. The second chamber may be fluidly sealed or separated from the first chamber and may house electrical components. The tortuous pathway may include varying stepped segments having a decreasing diameter from a proximal toward a distal end. For example, a first segment at the proximal end may have a larger diameter than a second, middle segment. An entrance to a third segment from the second segment may have a greatly reduced size. The tortuous pathway may further include a vent inlet positioned at approximately the same height as the entrance but requiring an approximate 180? turn therebetween. The inlet may extend into two opposite substantially horizontal portions that each lead to a vent outlet on opposite sides of the sensor adapter. The turn from the inlet to the substantially horizontal portions may be approximately 90?. The sensor adapter and tortuous pathway may mitigate aeration of DEF. The sensor adapter may prevent aerated DEF from entering the sensor adapter and may allow air to vent out of the sensor adapter to prevent aeration of DEF within the sensor adapter.

An embodiment of the present disclosure provides a damping component. The damping component includes a housing, at least one sliding piece, a fluid, and at least one damping elastomer. The housing may have at least one opening. The sliding piece slidably seals the opening, and partially protrudes outside the opening, to form an accommodation space within the housing. The fluid can fill up the accommodation space. The damping elastomer can be disposed inside the accommodation space.
