Abstract
Servicing devices and methods of use for servicing refrigerant systems are described herein. The servicing device may include a body and a plunger. The body may include a first fluid port, a second fluid port, and a passage. The first fluid port operatively couples to a fluid port of a fluid source. The second fluid port operatively couples to a refrigeration system. The passage is in fluid communication with the fluid ports of the body and in fluid communication with a measuring device. A plunger is at least partially disposed in the passage of the body. A first portion of the plunger is engagable with an integrated valve of the fluid source. Adjustment of the plunger to a released position allows communication between the second fluid port and the measuring device while inhibiting communication between the first fluid port and the fluid source.
