A method and apparatus for servicing a refrigeration system, and which has means 200 to communicate between the refrigeration system and a refrigerant supply outlet, the refrigerant supply outlet including either a self-sealing valve (122 fig 3) or a seal that requires puncturing, and the means to communicate with the refrigerant supply is able to connect to both the self-sealing valve and the seal that requires puncturing. The means to communicate includes an outer housing 206, a central body 136, a valve 204, a valve actuator 140 and a supply port 148 to connect to the fluid supply outlet. The central body includes a first port 144 able to connect to the refrigeration system, and may include a second port 146 which connects to a measurement device 102. The valve may allow selective communication between the first port and the supply port, and between the first port and the measurement device.
