Description

Bulkheads are used to attach plumbing to aquariums and sumps to allow water to flow through them. These low profile reef safe bulkheads are made from black ABS plastic. Our supplier manufactures these slightly thicker than competitor aquarium bulkheads making them more reliable.

Our Bulkheads come in different sizes That the PVC Pipe will “Slip” into. The PVC Pipe will Slip into the bulkhead to make a connection. Slip fittings will require a solvent to bond the bulkhead to the plumbing permanently.

When measuring for bulkheads, you will need a hole in your tank that is slightly larger than the “C” measurement for the corresponding bulkhead but no larger than the “A” measurement. (see image)

Example: If you have a 1.33″ or 35mm diameter hole currently in your tank, then you would want to use the .75″ or 3/4″ ABS Bulkhead.
