These unseals are very helpful, esp for the small sizes, where you may not want to use a bulkhead, use these uniseals. They are great, I used them in my refuge when I drilled holes in them. I also used them in my DIY BP reactors.
They are easy to use and they do not leak, just make sure you drill the right size holes.

These have amazed me. I've used them on all kinds of things including rounded Brute trash containers. Not a single drop has leaked. Love them!

I installed two of the 1 1/2 inch seals into a 55 gallon garbage can being used for water storage. Inserting the 1 1/2 inch PVC did take a little effort but wasn't all that hard. Have been monitoring for leaks but seems to be sealed up good and tight.

I just installed these on a 30 gallon container, and they worked slick. Very easy to use with no leaks. Anyone saying that they have had problems, probably did not use the correct hole saw, otherwise its easy as pie

Very handy for D.I.Y. ers... By Ksig on 3/11/13

This is a great peace of equipment, simple but very effective, and durable. If you're into plumbing or just a D.I.Y. er (lol) like I am it's a must you keep some of these in the tool box.

Been using these for years, never failed me.
As far as using the larger pipe sizes I round off the flat end and use a ratchet tie-down strap to push it in

Horrible By Steven on 1/27/13

This is the worst product I have ever purchased in my life. After several hours and multiple cuts and blisters I got 1 our of 10 on. They don't say in the examples that you need to cut off the end of the pipe to actually get pipe through the uni-seal. Even with that and pipe Lube it's almost physically impossible. I am a competition power lifter so I wouldn't say that I am weak, and the amount of muscle you need for these 2" seals is unbelievable.

These work great! By Eric W on 1/2/13

I bought some 3/4" uni-seals for my RODI/WC station 15gallon plastic drums. These work flawlessly - no leaks and simple to install!

Great for RO-DI container By Jeremy on 10/24/12

Jeremy would recommend this product to a friend

When first looking at this product I was a bit sceptical. Even after drilling the hole and inserting the fitting I was not sure if it would hold. After inserting the pipe into the fitting, there was no leaks. Very easy to install and works great.

Work perfectly By Mike on 8/30/12

Easy to use and works everytime. I've even been able to pull it out of the hole and re-use it. I didn't think that would work but the seal is holding just perfect.

Ordered these for my water change station. I was a bit skeptical upon first inspecting these, but they get the job done. No leaks what so ever.

Wow By Luis on 6/6/12

I was worried about leaks. But once the pipe went in and with the tight fit I was very happy with the result.

I was worried about them at first but once I put them in I was very happy with the outcome.

I was going to use bulkheads on my 55 gallon drums and just crank them down and hope for the best, but this product is by far a better choice and allows me to put my holes just about any where. Very happy with how easy this product is to use and how it performs. If your considering bulkheads, give these a try!

a great alternative By Richard on 3/27/12

I was a little skeptical at first, but once i installed on the curvy sides of a 55g drum, it holds like a champ, no leaks and tight seal on a curved edge

PERFECT! By Darrin on 3/9/12

where have these things been all my life? No more wondering how to tap the side of a 5 gal bucket!

I really didn't think they'd work very well, but they're very sturdy

Right tool for the job. By drolic on 1/12/12

drolic would recommend this product to a friend

These things are great. All reefers should keep a good supply of RO/DI or mixed salt water on hand. With this and a Brute trash can you can easily have plenty of water stored and accessible. The uni-seal is the only way to go when it comes to low pressure applications and installing a bulkhead on a curved surface.

Great alternative! By Seth on 12/19/11

Works really well, no leaking at all. I had a hard time getting the pipe through the bulkhead at first, I had to sand the hole a little bigger, but other then that its a great product

I purchased some of these to make connections to a DIY canister filter. After drilling hole to the specs listed, inserting the uniseal was a breeze! Installing the PVC through the uniseal was just as easy, just follow recommendations of using windex as a lubricant. Ordering more for my sump!

True bulkhead alternative By Ishan on 9/14/11

These were very easy to install. The tricky part is to put the PVC pipe in. Solved the issue by applying a tiny drop of silicone lubricant on the pipe and spreading it all over.

Easiest Bulkhead I've Installed! By Andy on 8/25/11

Andy would recommend this product to a friend

These are sooo easy to install. Just drill the hole, clean the hole, lub the uniseal, install it, and push in the pvc pipe. The are so much cheaper than standard bulkheads and no more pvc primer/glue.
