One thing though, the extra barbs it comes with felt a little funny to me. They felt like plastic [not saying they are plastic], so i decided to remove the stock ones and use my leftover 3/8 D-Tek barbs, if they can be attached that is. As you might noticed, I've looked at it but I have not really messed with it.

The block is made out of copper, but the top is made out of anodized aluminum. The barbs are a little lite for my taste, so I removed them and went with the D-Tek barbs I had leftover.

If you don't have extra barbs or just don't mind using the ones provided, you need not do anything, the block is built with the gasket is already in place [the one you see in the accessories box is an extra].
