Which is BETTER Flex Seal or Flex Tape?

Which is better, Flex Seal or Flex Tape? I’ll take a look at both products and see how they compare. We also ask the question: which is best for plumbing? Flex Seal and Flex Tape are sealants that you can use to fix leaks in roofs, gutters, pipes, and more, but which one is better?

We already knew that tape doesn't work for that. Roger just wanted an excuse to have his own wet t-shirt contest. Lol.

What I used flex seal spray for was sealing the bolt holes in my fitting bins in my work truck because the old truck always leaked at the bolts. That about the most I would trust flex seal for

Great video, Roger, I used flex tape on some similar pipes, but it doesn't hold up to water pressure, but works great for holes/leaks in rain gutters and on some drain pipes !, and yes it will hold that small canoe together!!

I patched 2 pen size diameter holes on my above ground pool, I sandwiched the holes with flex seal tape, then used 2 strong magnets to clamp the everything together overnight. 3 years later still holding strong 💪

What you need is Flex paste, much thicker

[sephirrothvt]

Man those hands though, Roger is a real professional with the hands of a handyman

[theschmedaparadox]

Tape all the way, It's what saved the boat 👍

[bobduffy]

LOL. Great editing. Can’t wait for next vid. Btw. I used a plumbing bladder the other day. From drain king. It worked wonders. No more backed up sink!

[brendastolecki]

I also suggest using a heat gun or hair blowdrier to heat up the tape after it is in position to enforce the adhesion.

[anthonyberube]

Oh my God I can't, .. I love watching your videos, this one's a good one!
The can shaking action was top par!

I haven't been impressed by any of the "Flex Seal/Tape" products. I do however, have a waterproof tape that I have used numerous times on outdoor projects, and I recently had a plumbing repair that got out of control, I grabbed my T-Rex Waterproof Tape and it did hold the water leak until I could slap a sharkbite end stop on my pipe. It's not a permanent solution by any means, but it is a great tape to use in water repairs. Much better than Flex Tape! Try it and tell me what you think.

What about several rounds of wrap over leak instead of one? I wouldn't expect the single wrap would do anything under pressure. Just tossing it out there.

[wbmgr]

I never thought either of these were worth a durn… till I used the tape. I bought some of the 4” tape and used it to fix a low pressure air line and it makes an air tight seal. Admittedly we are under 20 psi.

The key is to make sure it sticks back to itself.

Some info about pex: pex or cross-linked polyethylene is some of the most adhesive resistant materials known. There are no glues or other adhesives that will stick. Theoretically maybe a tape that creates a large enough compression forces might be able to work. Even on all of the pipes, the adhesive force is not enough compared to the water pressure. The water pressure just peels the tape off little by little until it leaks out the side. The tape is too rubbery so it just stretches until it bubbles out so if there was maybe a reinforced version it might work better

Flex seal would probably work for the weekend if you combined it with something that wraps tighter (like vinyl tape). The optimal use case however is in situations where you can apply it from behind the hole rather than over the hole...granted this would basically apply to any patch with a respectable sealant.

[PaulRuckman]

Part of my job as a plumber is health and safety, never put any unknown chemicals into a water system! Period!!!!

[Boodieman]

It probably says that about potable water systems because of any chemicals it might release.

[NotRiansLuke]

Try using the tape combined with hose clamps. Use 3 clamps -- one directly over the leak, then one on either side.

[nobodycaresaboutchicken]

I used tape on a pipe that continuously drained out. There was no way for to replace the pipe right away. It lasted for a few months till I got the pipe replaced. I wonder if they will come up with a high pressure version or better yet use a heat gun to seal it to the metal pipes.

You need Phil’s god like slap to stop leaks
