Abstract: A cover is provided with a body including an internal periphery shaped to receive one of a fastener, a plug and a knob in the body; and a magnet positioned within the body. The magnet removably couples the body to the received fastener, plug or knob when positioned in the body. Preferably, an internal periphery of the body closely conforms to an outer periphery of the fastener, plug or knob to be received therein.

Abstract: A reed valve assembly is provided with a body, at least one flexible member, and at least one rigid member. Preferably, the at least one flexible member has a periphery so as to substantially cover opening(s) in the body when positioned adjacent to the body, and the at least one rigid member has a periphery so as to limit deformation of the at least one flexible member.

Abstract: A fluid line connector system provides for connecting a fluid line to an article such as a fluid chamber. The wall of the fluid chamber has an orifice formed therein with a threaded portion. A fitting has a body with a hexagonal passage extending there through. A first end portion includes an interior tool receiving profile having a substantially hexagonal profile. A second end includes threads configured for inserting into the orifice. An exterior of the first end portion includes a raised ridge over which a fluid line is attached. A clamp engages the fluid line over the fitting and retains the connection in place.
