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 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. 

 

Example: If you have a 1.75" diameter hole currently in your tank, then you would want to use the 1" ABS Bulkhead.

Product Questions

One of the reviews states that this doesn't fit standard pvc fittings. Will this be the case with the reducing bushings you guys sell here?
Question by: Paul Corrao on Feb 18, 2023, 12:38 AM
This fits all standard PVC fittings. This bulkhead will have an internal female thread and an external female slip. You cannot thread onto the external male threads as those are not a standard thread size and are designed only to be used with the included bulkhead nut.

Do they make this but as an adapter bulkhead? 1 inch slip x 3/4 threaded? so i can go right to lockline.
Question by: Patrick Hamilton on Jan 22, 2020, 6:12 PM
Hey there!

Unfortunately not, you would need to get a reducing bushing that we have in our sch 80 fittings.

Take care
