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. (see image)
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
All of the ABS Bulkheads come with a gasket to create a leak free seal.
If you have any other questions just let us know.
There is no need for a wrench with a bulkhead. it can be hand tightened and with standard channel locks or other tools tightened down further.
With a return pump of 660 GPH we recommend using 1 inch drain lines. This means 1" bulkhead and 1" pipe will be a great fit! The 1" has a gravity fed flow up to 650 GPH and by the time your return pump pushes up the head height the flow into your tank will be well under 600. Feel free to let us know if you have any further questions!
You will use PVC to ABS transition cement. Currently one option from many hardware stores is Oatey Green. Feel free to let us know if you have any further questions!
If you have a 1" PVC pipe you would want the 1" bulkhead for that pipe and 3/4" bulkhead for 3/4" pvc.
All the plumbing sizes are nominal, so a 1/2" PVC pipe will fit in a 1/2" ABS bulkhead no problem.
I just bought some bulkheads.
1) 1 1/2" ABS Bulkhead Slip X Slip Dimensions
2) 2" ABS Bulkhead Slip X Slip Dimensions
I need to drill holes for these bulkheads. There are A, B, C hole sizes. Which one do I use for acrylic? These hole saws are all a little different and I want to make sure I choose the right hole saw.
Thank you!
The ABC are dimensions, not hole sizes :) Dimension C is the size of the part that goes through the tank so you need to make sure the hole is that big, but not larger then A or B which is the size of the head and the nut. Generally speaking you want to go with the closest size drill bit to dimension C that is at-least the size of dimension C.
