## Questions & Answers

**Q: Do they hold anykind of pressure?**
A: Some - haven’t tested it, but if you’re using it in  the wall of anything that’s not metal (e.g. plastic drum, 5gal bucket) it certainly will be sufficient. The vessel would fail first. It will hold 20’ water head pressure no problem.

**Q: I want to use them in a solar evacurated vacuum tube system.  ?Will outdoor weather, sun, or hot water destroy them?**
A: I'm using them in outdoor fish tanks - in the sun.  They seem immune, so far, after 3-1/2 years.  They are vulcanized rubber, like tires.  You know how long it takes a tire to dry rot in the sun?  Consider these the same, I think.  They're really great..  Keep in mind, in your design, that they can only go through in one direction.  I suggest you use a short piece, right at the uniseal, and connect it with a flexible hose coupler, to any longer piece.  That's how I use them.  Otherwise, dismantling a/o moving can be a big hassle, or you'll have to cut the pipes that go through the uniseal before you can dismantle yoru system.

**Q: Do you send this to Brazil?**
A: Im sure they will.

**Q: will it function if the tank wall thickness is 1/2"?**
A: Thicker the better, really thin plastic makes it harder to work

## Customer Reviews

### ⭐⭐⭐⭐⭐ 1) Boil  2) Taper  3) Soap = Easy Install
*by M***L on March 21, 2021*

Here's the trick: 1) Boil the seals 2) use a Dremel/grinder to taper down the ends of the pipe and 3) use soapy water.I did all of these things (as suggested in other reviews) and installation was pretty easy. It still required a bit of muscle. But I was able to install each seal/pipe in about 15 seconds (After the prep).The seals are tight, no leakage. I used a 3" hole bit to install these 2" seals. Worked great!

### ⭐⭐⭐⭐⭐ These are much better than bulkhead fittings!!!
*by A***. on January 7, 2025*

I know bulkhead fittings have their purpose but if you need to quick plumb a pipe into just about anything these are just awesome. And reusable!!! Better than I expected them to be and they are standing up well in the heat and direct sunlight. Much cheaper than bulkhead fittings and these are quality genuine uniseals. If you need help installing them or for some tips and tricks go see rob bob on yt on any of his filter builds. I love these things!

### ⭐⭐⭐⭐⭐ So far so good
*by R***T on May 24, 2022*

So far so good, It was easy to install as long as you used a sander or a file to round the edge down of your pvc pipe, or to thing the edge of the pipe it make it much easier the to force it in. Remember only the edge or tip of the pipe. Add a little Vaseline you don’t cut the seals causing it to leak. seems to be of good quality, work perfect but only time will tell
