Disclosed is a diesel exhaust fluid (DEF) breather comprising liquid separation baffles that "dry" exiting air and reduce crystal accumulation on surfaces. The baffle may comprise zig-zag pattern. The zig-zag pattern may cause or provide a change of direction of the air flow stream, which in turn causes or assists in promoting fluid droplets to shed off the walls of the baffle and prevent crystallization of the fluid on the walls of the baffle or other seals or surfaces of the breather.

RETAINER SHIELD WITH WEDGE LOCK FOR DIESEL EXHAUST FLUID SENSOR
Disclosed is a retainer shield, mating filter, and assembly for diesel exhaust fluid (DEF) systems. The retainer shield, mating filter, and assembly may prevent aerated DEF from entering into an associated measurement chamber including one or more sensors, which can contribute to inaccurate measurements and sensor readings. In an embodiment, the retainer shield may comprise a wedge lock on an interface between the retainer shield and a mating filter. The wedge lock may be positioned on opposite sides of the retainer shield, for example, on the straight or linear sides of the retainer shield. In an embodiment, the retainer shield may comprise a shield that generally corresponds to and covers a central porous membrane of the mating filter. The shield may protrude and provide a space between the shield and the mating filter. A bottom end of shield may include an open portion and a top end of the shield may include a vent hole.

Disclosed are improved hose fittings and methods of assembly that are adaptable to a variety of metal tube and/or hose sizes without the need for expanding the metal tube and without requiring multiple iterations of the metal tubes and/or hose sizes on hand. The hose fitting may include a cavity on a proximal end of the hose fitting that is configured to receive an O-ring and a distal end of a spacer. A proximal end of the spacer may be positionable outside of the hose fitting and between the hose fitting and an external stop point on the metal tube. A distal end of the hose fitting may generally align with a distal end of the metal tube when the hose fitting and components are assembled thereon. Flaring of the distal end of the metal tube into a clearance space within the distal end of the hose fitting may increase the outer circumference of the metal tube, securing the hose fitting and preventing the hose fitting from being removed. The spacer, as a result of pressure from contact with the external stop point may compress the O-ring against an edge of the cavity and form a seal. The hose fitting may be configured to receive a hose or other component of the system.

DIESEL EXHAUST FLUID SENSOR ADAPTER FOR FLUID AERATION MITIGATION
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.
