Pawfly Multi-Way Air Manifold

A fish room with a row of tanks needs one air source shared out evenly, and this manifold does the sharing. Air enters through a 3/8 inch inlet and leaves through 6 or 8 outlets of 3/16 inch, each with its own lever. The body is chromium copper, so the joints hold air, and the 8-way version weighs 0.4 pound and measures 6.3 by 2.3 by 0.25 inches.

Because the inlet is the wider size, plan a 3/8 inch line from the pump, or an adapter down to it. Each lever can also shut a tank off while you service it. Size the pump to the number of tanks, since the manifold divides air rather than adding any.
