This new reservoir from Bitspower is the ultimate addition to your DDC Laing pump! The new 403 series reservoirs connect to any Laing DDC pump such as Swiftech, Koolance, Alphacool, etc. Just add any acrylic top. The difference between the ADP and AGP versions of this res are that one uses a dual G 1/4 fitting and one uses a D-Plug quick-release fitting between the pump DDC top and the res. Take your pick! Like all Bitspower components these are some of the most premium products in the water-cooling industry. This is the perfect new addition to your new water-cooled PC!
