4 pack of 1/2” Bulkhead ABS Slip x Slip​

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.Bulkheads come in different sizes and either with or without threads for plumbing to connect to. With threaded bulkheads you will need to use a male pipe thread to screw 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.
