Abstract
Servicing devices and methods of use for servicing refrigerant systems are described herein. A servicing device may include a body and actuator. The body includes a first fluid port that is coupleable to a fluid port of a fluid source; a second fluid port, that is operatively couples to a refrigeration system; a passage in fluid communication with the first and second fluid ports and in fluid communication; and a plunger at least partially disposed in the passage of the body, and the plunger is adjustable between a released position and an engaged position, during use. The actuator is coupled to the body, and, during use, downward movement the actuator raises or lowers a plunger such that substantially continuous fluid communication between the first fluid port and the second fluid port is established.
