Abstract: A device for at least partially blocking an opening includes a first body, a second body rotatably mounted to the first body and a compressible seal extending from the first body. The seal includes a first portion, a plate having a hole at one end of the first portion, and a second portion extending away from the plate. A hollow shaft extends from the second body and through the first body, the first portion, the hole in the plate, and into the second portion. The shaft has a shoulder in the second portion that is wider than the hole in the plate, and moving the shaft relative to the first body compresses the second body until the shoulder reaches the plate and then compresses the first body. Such compression expands the first and/or second portions and presses them against the inside of the opening to form a seal.

Abstract: A device for evacuating and filling a vehicle cooling system includes a housing having an interior chamber. A service port extends into the housing and connectable with the vehicle cooling system, a supply port extends into the housing and connectable with a source of coolant fluid, and an evacuation port extends into the housing. A valve is disposed at least partially within the housing chamber and is adjustable between a first configuration in which the service port is fluidly coupled with the evacuation port and a second configuration in which the service port is fluidly coupled with the supply port.

Abstract: A device includes a first body having a curved wall with a top surface that slopes away from the first body and a second body having an interior configured to receive the curved wall of the first body, the interior including a curved ramp with a sloped bottom ramp surface. The second body is mounted on the first body with the bottom surface of the curved ramp resting on the top surface of the curved wall. A compressible seal extends from the first body bottom, and a shaft projects from the second body through a passage in the first body and into the interior of the compressible seal. Rotating the bodies relative to each other causes the shaft to pull the seal against the first body and radially expand the seal against an interior wall of an opening in which the device is placed to form a seal therewith.
