Pipe Thread Sealant?

[EdsReefOdyssey]

Looking for pipe thread sealant that’s saltwater safe and will work with PVC and ABS. Any recommendations?

 

[Crabs McJones]

I believe any thread sealant would suffice, otherwise BRS sells this

I use Oatey joint compound paste with Teflon...

Tough to beat Plasto Joint Stick on plastic pipe threads. I will never use Teflon tape again on plastic threads.

That's the best stuff to use for us IMO, no mess either. Should never be using teflon tape on plastic, it's meant for metal fittings. @EdsReefOdyssey, I've done about 20 fittings with the laco stick and zero issues.

Teflon tape is for metal, the Oatey paste with Teflon that I referenced, as well as the Plasto Joint Stik can be used and works very well for sealing PVC and plastic threads.

Clear silicone is all I ever use and have never had a leak. This was based on information from Bill Wann when I was starting my tanks.

I used this for PVC to PVC threads, it worked great. It says use for plastic pipe so ABS could work.

Probably the best sealant is one that is designed for plastic pipe.

Many use the teflon thread tape and get away with it forever.
But there is always the danger of using too much AND at the same time over tightening it. The result can be a split fitting and water on the floor.
In my case it happened sometime during the night and when I got up at 4am to get ready for work there was about 60 gallons of saltwater on my kitchen, dining room, and living room floor.

I second the use of clear silicone.

Use teflon, or silicone. I use teflon to service in future.

I have used joint compound but now I usually just use silicone

Silicon is very easy to remove from the threads when servicing

Silicone. Never leaks and easy to remove should you need to.

 

[EdsReefOdyssey]

Thanks again for all the info!!

I think what I’m going to do is use thread sealant on the DT plumbing and experiment with silicone on the sump plumbing in the basement. I’m not 100% sold on silicone yet.

 

[EdsReefOdyssey]

@pluikens is this the Bill Wann video where you got the info about using silicone?

 

[EdsReefOdyssey]

After watching this video I have a few questions.

GE silicone 1 seems to be popular on this forum. Is this the silicone you guys like to use as a thread sealant or do you use a different brand?

How well does silicone stick to PVC? Do some brands stick better than others?

I’m thinking the better it sticks the better it will hold up over time. My only concern would be if it sticks to well will you be able to get it apart again in the future? What do you guys think?

I think silicone on plumbing is a terrible idea. Just buy the products that are designed for use on plumbing.
