Bulkheads allow plumbing to flow through your aquarium or sump.

Heavy duty Schedule 80 PVC bulkheads feature some distinct advantages over ABS bulkheads:

  • O-Rings are 2X as thick as ABS O-Rings
  • Schedule 80 construction will far outlast ABS
  • Reliable seams
  • Flange and nut side are very easy to grip

 

When measuring for bulkheads, you will need a hole in your tank that is slightly larger (1-3mm) 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 3/4" Sch 80 Bulkhead.

Can these bulkheads be used with schedule 40 tubing as OD is the same?
Question by: Christian Erhardt on Dec 4, 2022, 4:28 PM
0
That is a great question. The SCH 80 fittings can be used with SCH 40 Pipe of the same size.

Hi,
I have several of these bulkheads in my aquarium and Sump - can you please tell me if they are ozone safe (bulkhead and o ring)?
Thanks
Question by: Andrew Sweeting on Mar 21, 2022, 2:22 PM

Hey Andrew, thanks for the question! Technically they would likely be fine but we recommend using an Ozone Reactor.

Hi, does it matter which orientation the bulkhead is inserted just so as long as the rubber gasket is on the inside of the tank?
Question by: Robert on Sep 13, 2020, 6:27 AM

No, it does not matter. Only for aesthetics.

Currently, I just got done finishing up my saltwater mixing station and I used the Uniseals for my 35-gallon Brute food grade garbage cans and my Uniselas are leaking. If I was to add two 1'' Bulkhead Schedule 80 Slip x Thread would it work out better? Or since the bulkheads are going to be at the bottom of each Brute can would that be a problem... Let me know your thoughts when you get this?
Many thanks,
Matt Paul

Unfortunately bulkheads are really only meant to seal well against flat surfaces, and due to the curved profile of the cans, these can be a problem. If you are getting leaks around the uniseals, I would ensure that you are getting a snug fit, as they do depend upon this pressure to get a good seal, and you may also want to look at putting some aquarium safe silicone or grease around the insertion point to improve the seal between the two materials.

Happy reefing!

What spigot or fitting goes on the threaded side of the bulk head to connect to slip pvc? Thanks
Question by: Roy on Jun 2, 2017, 9:17 AM
0
All bulkheads use NPT ID threads. For connection to pvc, you'll want a male pipe adapter of the appropriate size. For instance, on a 1" bulkhead from our website, connecting to 1" pvc pipe, you'll use a 1" male pipe adapter. All of our fittings are nominally rated for the PVC ID to avoid confusion.

Hope this helps!

Hi, I purchased your 1 inch and 3/4 inch schedule 80 bulkhead fittings. I called your site and spoke to a representative and asked if I should purchase the 48 mm and 42 mm drill bits to cut my acrylic tank to fit the bulkheads. He said I should purchase the hole cutting kit to cut acrylic, which I did. My question is what hole cutter to use for these bulkheads. 48 mms = 1.89 inches and 42 mms = 1.65 inches. The kit doesn't come with those sizes. What should I do?

Thanks,
David

Hi David,
The holes just have to be large enough for the spindle of the bulkhead to go through, but small enough that the flange, o-ring, and nut still have something to grab onto (i.e. bigger then dimension C but smaller than dimension A). This leaves quiet a wide area to work with but best to err on the side of a smaller hole rather then a larger one. In your case with those particular bulkheads you would use a 2" and a 1.75" bit.
Answer by: Bulk Reef Supply on Apr 7, 2014, 1:41 PM
I have two 1" holes drilled in an existing tank that currently fits the ABS bulkheads. My question is, can I switch to the schedule 80 bulkheads or will the holes not match up? If those bulkheads won't work, would I be able to use the schedule 80 pipe with the ABS bulkheads? Just wanted to clarify before I purchased.
Question by: Craig on Dec 4, 2013, 4:29 AM

Hi Craig,
Unfortunately the holes would not match up. The sch80 bulkheads require a significantly larger hole but the sch80 pipe will work just fine with the abs bulkheads.

Do you stock slip x slip?

Hey Glenn,
Sorry but those are unavailable in the sch80 bulkheads. We do however have them in ABS bulkheads.
