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

Hello
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!
Question by: Tanner on Apr 23, 2014, 9:28 AM
Hi Tanner,
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.

Do these bulkheads come with the required wrench? If not, where can I purchase one?
Question by: alex razo on Jul 3, 2016, 10:46 PM
No,
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.

What is your recommended "reef safe" solvent to join PVC pipe to ABS slip bulkheads?
Question by: Ken Smolana on Apr 3, 2016, 9:56 PM
Great question!
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!
Answer by: Connor on Apr 6, 2016, 5:33 PM
Do these bulkheads include the rubber gaskets as well?
Question by: John on Jul 8, 2016, 1:53 AM
Hi John,
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.

I have a 75 gallon tank that's going to have a 660GPH return pump and RSS18 large overflow box. How do I determine what size plumping is appropriate? I plan on having a main overflow and an emergency overflow.
Question by: Mel on May 31, 2016, 1:39 PM
Great question!
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!

I have a pre-drilled tank that came with barbed bulkheads and I am converting to slip. I need a 1" I/D (inside diameter return) and a 1-1/4" I/D supply. The diameters listed do not specify inside or outside according to conventional plumbing. Thanks for your help.
Question by: david marcinkewicz on Jan 12, 2017, 1:12 AM
Great question! The bulkhead sizes will match the size of SCH40 or SCH80 PVC pipe you intend to use. So, if you plan to hard plumb the aquarium with 1" PVC, you would need a 1" bulkhead. :-)
Answer by: Randy on Jan 12, 2017, 9:32 PM
Will a 1/2 inch PVC pipe fit in the inside diameter of the 1/2 bulkhead? Or is the inside diameter of the 1/2 in bulkhead exactly 1/2 inch? If that is the case will a 1/2 inch PVC inside connector fit in this bulkhead? Thanks

Hi Jimmy,
All the plumbing sizes are nominal, so a 1/2" PVC pipe will fit in a 1/2" ABS bulkhead no problem.
Answer by: Bulk Reef Supply on Jul 10, 2014, 1:12 AM
Which bulkheads will i need ? Im doin 1"pvc in overflow and 3/4" pvs from pump. Which bulkheads will fit these pvc sizes?
Question by: dan on Jul 31, 2014, 10:44 PM

Hi Dan,
If you have a 1" PVC pipe you would want the 1" bulkhead for that pipe and 3/4" bulkhead for 3/4" pvc.
