Abstract: A device for removing oils, fuels and other fluids from reservoirs is disclosed that works in conjunction with engine-powered devices via a vacuum-actuated valve containing a multi-tiered U-groove. The U-groove allows a disconnection of the valve bolt shaft from the threaded end that fits inside the reservoir, trapping and holding the fluid in the reservoir.

Abstract: An environmentally-friendly hose plug may include an insertion section having a size selected for plugging a hose. The insertion section may be attached to a knob at a distal end of the hose plug through a gripping section. The gripping section provides a number of ridges to improve a technician's ability to handle the hose plug. The insertion section reduces the exertion of force by fluids in the hose against the hose plug. Thus, the hose plug is less likely to be forced from the hose by fluids in the hose. The insertion section may include one or more sealing rings for further reducing the leakage of fluids from the hose.
