The FrozenCPU Mini DDC Water Tank Pump Top is designed as a replacement top for Laing DDC-1T & 1TPlus pumps as well as the Swiftech MCP-350 & MCP-355 pumps. Adding an 85 ml reservoir to the pump saves the space used up by a separate reservoir and tubing needed to connect it to the pump.
The Laing DDC Series Pump Replacement O-Ring Pump Replacement O-Ring can save you from getting a new pump. Replace the old worn out o-ring and you are off and running again!
