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.
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.
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.
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!
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.
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!
All the plumbing sizes are nominal, so a 1/2" PVC pipe will fit in a 1/2" ABS bulkhead no problem.
If you have a 1" PVC pipe you would want the 1" bulkhead for that pipe and 3/4" bulkhead for 3/4" pvc.
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.

Bulkhead By herring_fish on 8/16/2017herring_fish would recommend this product to a friendThey work pretty well.
I've used them a dozen times before and they always work for me. By JJ on 7/18/2017JJ would recommend this product to a friendThey do their job. What else do you need to know.
Inner Rim Doesn't Fit Overflow By Patrick on 12/5/2016Patrick wouldn't recommend this product to a friendI got the 1" to replace a bulkhead that had started leaking on an Eshopps overflow box. I measured the hole size on the box and ordered the appropriate bulkhead. The hole size is correct and the threads fit through the hole, no problem. However, the rim that goes on the inside of the overflow (part A in the diagrams) is MUCH wider than the original bulkhead. It won't fit in the chamber of the overflow box where the bulkhead goes. I'm going to have to cut two sides flat so it fits into the chamber.
TL;DR: if you have an Eshopps overflow box, measure all dimensions of the bulkhead to ensure you get a proper fit. Or break out the Dremel/other rotary cutting tool.
Great Bulkheads By Batfish Aquatics on 7/14/2016Batfish Aquatics wouldn't recommend this product to a friendWith close to 400 tanks, we use a lot of bulkheads in the shop... especially since we're always tinkering with stuff. I've bought lots of different types, some cheaper than this... and I've replaced lots and lots of cheap ones. The cheapies start leaking, they just plain break, ugh. These ones from BRS are sturdy and durable, go on easily without any cross threading or other issues, and stay put, tightly. Well worth it!
Super Duper By T-Bone on 5/6/2016T-Bone would recommend this product to a friendPerfect fit form and function. The fish said it's not leaking so were good.
Works as intended By James on 2/21/2016James would recommend this product to a friendWorks exactly as you would expect a bulkhead to work. The only complaint i have is more against BRS than the product. The drill hole and the bulkhead both list different recommended sizes for each other so that was a little confusing.
Looks good! By Jessica on 12/28/2015Jessica would recommend this product to a friendI haven't installed this bulkhead yet since there was a delay on my sump, but the quality looks to be as good or better than most that I have seen. I would purchase again.
Great Product By MaroonMan on 11/9/2015MaroonMan would recommend this product to a friendGood quality bulkhead. Have purchased several and all have worked well

not happy By Steve on 7/15/2015Steve wouldn't recommend this product to a friendvery thin top half, sent them back
Poor PVC Fit By tbrehm on 3/16/2015tbrehm would recommend this product to a friendPurchased 2 BRS 1" bulkheads from online and a local supplier and both have extra material on the inside of the bulkheads that does not allow pvc to fit. I suspect there is a problem with the supplier's molding process. Can be taken care by sanding the inside of the bulkhead.
