A wheel end assembly, comprising:

• a hubcap configured for coupling to a wheel and defining a chamber that retains lubricant for wheel bearings for said wheel, a first wall of said hubcap having an aperture in fluid communication with said chamber;
• a plug disposed within said aperture and extending in an outboard direction from said first wall of said hubcap, said plug having a body and defining a valve that releases pressurized fluid from said chamber;
• and,
• a cap having:
• a first member supported on said body of said plug
• a second member coupled to said first member, said second member disposed over an outlet of said valve and defining a first fluid chamber in fluid communication with said outlet and ambient air.
