The Laing DDC-1T/1TPlus MCP-350/355 Acetal Replacement Top is an innovative POM replacement part for the Swiftech MCP-350 & MCP-355 pump as well as the Laing DDC-1T and DDC-1TPlus pump. It reduces vibrations produced by the pump and makes the pump much more versatile as you can attach any G1/4" tubing fitting to it.

A new hat for your pump

This was extremely easy to install. You''ll need some hex wrenches, as the one that came with my top fit neither the stock or new screws...
I put this top on my Delphi 3.1 (350) and it did improve the flow rate by a small bit, but more importantly, my pump now supports fittings of my choice. The area around the threaded fitting ports is flat and smooth, so even the most deformed temperamental o-ring should seal with little effort.
The only real downside is that this top looks pretty goofy on the pump. It''s like the pump''s wearing a large foam hat.
I did not notice any change in noise or vibration.
excellent replacement top.

this pump top is sleek, very well built, and i do think the pump is pumping better and maybe even cooler than with stock. regardless its worth the price.
