- Uniseal Bulkheads
Why does BRS recommend this?
Uniseals are one of the secrets in life you wish you knew about years ago. By conforming to round surfaces they allow you to plumb directly into 5 gallon buckets, brute trash cans, or any round surface. They accept standard Sch. 40 or Sch. 80 PVC and allow DIY projects that once may have been very costly to complete much more affordable.
Uniseals are used to attach pipe to just about any container in situation where bulkheads will not work. The most common use is on curved surfaces such as storage drums, buckets or even other pipe.

Works after a lot of work By Lance A. Lot on 10/10/2016
Lance A. Lot would recommend this product to a friendSeals well on curved surfaces but they can be a bit difficult to install. Boil/ heat the seals and make sure the hole has no burrs. A little silicone based grease helps get the pipes through without destroying the seal. If the hole isn't big enough you may destroy the seal trying to force the pipe through. -
Nice option for most applications By JRB on 10/8/2016
JRB would recommend this product to a friendThese work very well. However, you must be careful how you prepare the hole. A good, true hole saw is useful. Cheaper ones can have bent teeth that will cut an oversized hole. Likewise, be careful not to enlarge the hole during your cleaning up (sanding) of the burrs. -

Best product for barrel systems By Greg on 9/17/2014
Greg would recommend this product to a frienduniseals are great, i picked up 8 of them to plumb a 3 barrel sump system and they work great, easy pressure fit, water tight, very durable, and pretty cheap! You can find them for less money, but BRS ships fast and is convenient. -
hole size must be exact By David on 9/15/2014
David would recommend this product to a friendused spade bit on a 20g brute but hole was a hair too big, knew as soon as I put uniseal in that it would never hold and it didn't. Might try with another style bit sometime. -
good By James on 3/14/2014
James would recommend this product to a friendfast shipping, dosent leak, what more can you ask for. Thanks!! -
Works Great for 200G Saltwater Mixing Station By Kyevey on 3/5/2014
Kyevey would recommend this product to a friendI bought 4 of the 1" Uniseal.
Had no issue with the installation. Seal fit snug prior to inserting the PVC. Once the 1" PVC was added it was a perfect seal, no leaks...
I've been using with high power Iwaki pump which creates a bit of vibration with the PVC and the Uniseals absorbs the vibrations much better than any Bulkhead could!
Great Product!
Will it work with tubings?
Question posted on Feb 27, 2014 3:28:00 PM
Hi Paul,
The uniseals are made to work with pipe. The diameter of the pipe pushes out and is what seals against the walls of the uniseal. A flexible tube would most likely leak.

If the OD of a 3/4" pvc is slightly over 1", you still use a 3/4" uniseal? I shouldn't bump up to a 1"?? Thanks for any info.

Hi there,
When it comes to PVC the best thing to do is take your tape measure and throw it away. PVC is nominal sizing and just because it says its ¾” you most likely will not find an exact ¾” dimension anywhere on the pipe. If your PVC is ¾” you will want to use a ¾” Uniseal, along with all other fittings and valves.

Witch uniseal will go into a schedule 40 1" pvc pipe. I am building the inline heater from he king of diy's YouTube channel.
Question posted on Jun 8, 2017 12:11:00 PM
Our fittings are based on the nominal pvc rating, so for 1" ID pvc pipe, you'll want to select the 1" uniseal.
Have a great day!

How thick can the wall material be? Can it be used on two walls like attaching an external overflow (similar to a ghost overflow)?
Question posted on Feb 10, 2016 9:26:00 AM
Great question!
We do not recommend using a uniseal on anything wider than 1/4-5/16". Feel free to let us know if you have any further questions!

If I were making a prob holder for my sump would a probe fit into the 1/2" uniseal?
Question posted on May 20, 2017 1:47:00 PM
Hey there,
I'm afraid the probes are a bit too small and would not be able to seal with a 1/2" Uniseal.
Regards

Are the prices listed, per uniseal? Or do these come in a package? If so, how many?
Question posted on Aug 16, 2016 3:02:00 PM
Great question! The price is per each individual uniseal. :-) Thanks!

Will they work with schedule 40 pipe?
If so, what diameter pipe for a 1 inch uniseal
Question posted on Aug 3, 2014 9:03:00 AM
Hi Chris,
Yes. All plumbing is sized with nominal plumbing sizes which takes into account the correct size fittings for the pipe regardless of whether they are sch40, 80, etc. For a 1" pipe you would want a 1" uniseal.

I am planning to use uniseals for my ATO, mixing, and water change tanks. What can I use for lubrication on the pipe that won't contaminate the water?
Question posted on Aug 13, 2014 5:32:00 AM
Hi David,
In the past I have actually just used water or saliva but many people recommend things like silicone o-ring lubricant, non-ammonia windex and vegetable oil. Just give the container a good rinse after everything is installed and you should be good to go!

Can a uni seal be reused? i need to pull the pipe out and install a longer one.
Thanks.

Hi Jack,
That is just fine. Just be careful removing it to not rip or tear on the uniseal and you will be just fine.
