Beckett injector with output flange

by Chris Paris for Reef Aquarium Information Depot

Here is a closeup of the Beckett injector and the output flange I made for it. The flange is an acrylic donut that is glued to the removable black plastic bit that comes with every Beckett injector. The outside of the flange has a groove cut in it to take an O-ring. The O-ring forms a watertight and airtight seal between the flange and the wall of the injection tube.

I made the flange on a machinist lathe. I can't think of an easy way to make this with household tools. I'm not convinced that it does any good anyway.
