Product Questions

Will it work with tubings?
Question by: Paul 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.
Answer by: Bulk Reef Supply on Feb 27, 2014 3:28:00 PM
Will they work with schedule 40 pipe?
If so, what diameter pipe for a 1 inch uniseal
Question by: chris 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.
Answer by: Bulk Reef Supply on Aug 3, 2014 9:03:00 AM
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 by: David 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!

Hope this helps!
Have a great day :)

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

Question by: Jack on Mar 17, 2014 11:42:00 AM
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.

Uniseal Installation Instructions

  • Cut hole to the hole saw size indicated for the Uniseal below.
  • Ensure that the hole is clean with no sharp edges. Irregularities can cause a poor seal and leaks.
  • Insert the Uniseal into the hole with the wide flange on the outside of the container.
  • Ensure the pipe end that will be inserted is clean of burs or sharp points. File the edges if needed.
  • Insert the pipe into the Uniseal. You can lubricate the pipe end with Windex. Most of it will be squeezed off during installation but be sure to wash thoroughly before turning on your system.

  • works great By orry on 7/28/2015

    I have used these in methane production, aquaponics and solar heating they work very well
  • AWESOME PRODUCT By JOE on 4/30/2015

    I USE THE 3/4 UNISEAL ON MY 35 GALLON RUBBERMAID DI STORAGE BARREL FOR DRAW OFF WATER WITH 3/4 PVC PUIPE AND BALL VALVE. IT HAS BEEN IN USE FOR ONE YEAR AND NOT ONE SINGLE ISSUE OR LEAK.
  • Best product for barrel systems By Greg on 9/17/2014

    uniseals 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

    used 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

    fast shipping, dosent leak, what more can you ask for. Thanks!!
  • Works Great for 200G Saltwater Mixing Station By Kyevey on 3/5/2014

    I 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!
  • GOOD By JWEPPEL on 2/26/2014

    BOUGHT THE 1", BE CAREFUL WHEN CUTTING HOLES. DID IT TO ROUGHNECK GARBAGE CONTAINER FOR SALTWATER MIXING STATION,AND STARTING OUT ON 2 OF 3 HOLES DIDNT QUITE CUT A CLEAN,ROUND, NO BURR HOLE. AND SOME LEAKED. WENT BACK AND PUT SILICONE ON THEM NOW FINE.
  • works as should By gavin on 2/18/2014

    i bought a the hole saw to make a water station for my tank. The seal was allittle loose but holds water good
  • Simple and easy By eric on 1/5/2014

    Used several of these on brute containers to build a water storage/mixing station. Work fantastic.
  • awsome By Denton on 12/25/2013

    This is an excellent piece great idea all the way around easy and fast
  • Excellent By Scott on 11/24/2013

    I used these on my salt mixing station. Perfect seal the first time on a rounded barrel. It does take a bit of work to get the pipe into the seal, but soapy water helps it along nicely.
  • Works, though some issues on very curved surfaces. By PuffDaddy on 10/15/2013

    These work well. Except when the surface is too curved in relation to the bar you are inserting. I attempted to put 1" PVC into a 3" PVC section. I was not able to insert the pipe. The 1/2" into the 3" worked like a charm though. I feel like these are intended for joining PVC to less curved surfaces. make sure your ratio of main diameter to insert diameter is above 4:1.
