- Bulkhead Schedule 80 Slip x Thread (Slip on the Flange/Head side)
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.

Wish they fit By dmhinz on 8/25/2018
dmhinz would recommend this product to a friendVERY NICE bulkhead, sadly it is too big for the factory drilled holes in my Marineland 180. -

Arrived warped By Neil on 2/8/2018
Neil wouldn't recommend this product to a friend2 out of 3 1.5” bulkheads purchased were warped along the mold seam making it impossible to force a pipe into the slip fitting. Heavy duty fitting but poor quality control in this case -
Trust By Jason on 6/12/2017
Jason would recommend this product to a friendWhen you have a need for a bulkhead you're putting a lot of trust in that piece of plastic. It's worth it when hundreds of gallons of water behind that piece of plastic to get the schedule 80 bulkheads IMO. This are big, strong and built to last. Keep in mind the hole sizes are different so if you're custom building something or using an existing setup the holes need to be increased. -
Good grip. By Garnett on 3/3/2017
Garnett would recommend this product to a friendI have a tank with standard square bulkhead and I had to burn it off. With these bulkhead it's easy to grip and turn. Easily to put on or take off...they're thick and really durable. -
Good quality product. By Christopher on 9/8/2016
Christopher would recommend this product to a friendThis is a heavy duty bulkhead that makes you feel secure that if the return plumbing gets banged or torqued-on it will not crack. Some ABS bulkheads are cheaply made and can crack or otherwise fail. -

Great Product By Desertdawg on 3/23/2016
Desertdawg would recommend this product to a friendReplaced the regular bulkheads with sch80. I wish I had used these the first time. -
Piece of Mind By Nickolas on 2/11/2016
Nickolas would recommend this product to a friendI started ordering sch 80 bulkheads after cracking a few cheap ABS plastic ones. I will never use anything but sch 80now. These things are extremely durable. -
Works well, By STarFishMan on 4/2/2015
STarFishMan would recommend this product to a friendThese are very nice and the gasket is beefy. Great although I was hoping for the slip end on the tank side rather than threaded. Maybe I missed that. Outside of this they are really nice and the price is right. -

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.

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 posted on Dec 4, 2013 4:29:00 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.

What spigot or fitting goes on the threaded side of the bulk head to connect to slip pvc? Thanks
Question posted on Jun 2, 2017 9:17:00 AM
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!

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
Question posted on Jun 3, 2017 9:24:00 AM
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!

Do you stock slip x slip?
Question posted on Sep 19, 2013 7:16:00 AM
Hey Glenn,
Sorry but those are unavailable in the sch80 bulkheads. We do however have them in ABS bulkheads.
