Slic-tite thread sealant works in extremely high-pressure systems, and it comes with several approvals to ensure industry standards are met.

Review: Good stuff - This stuff works great for ceiling pipe threads. I like to put this on my threads and then a little bit of Teflon tape over top of it or vice versa. Definitely worth the money. Great seal, easy to use, and easily removed with a towel.
Review: If it has threads this it!! - I've been using laco for 50 years of my life in the plumbing and gas fitting trade. High end restaurants,it seals the threads and has lubricant abilities which allows the fitting to tighten even better. Best part is years later when undoing fittings they come right apart. If I could give it 10 stars I would. Retired 4 years ago and yep got a bottle in my tool bag. Very easy to use and any excess wipes right off...

## Questions & Answers

**Q: My pvc sewer pipe threaded access point is leaking. will using this seal off the access point indefinitely or still allow access?**
A: It won't glue it tight but seal the threads from leaking! You can unscrew it off and on anytime but might need to add some off n on! Good stuff!

**Q: Would this be good to utilize on an oil drain plug before reinstalling during automotive oil changes?**
A: I wouldn't recommend that. This has bits of Teflon and they could get into the oil filter and clog it. Drain plugs are designed to have a gasket and not seal at the threads.  I would search for a new drain plug on Amazon for your car.

**Q: How to revive old dried out slic-tite, is it water soluble?**
A: Hello, This is not water soluble product.  This is actually an oil/grease-based material.  You can try a little ethanol.  However, you should only try a little bit.  Adding too much will likely have a negative impact on the performance of the product.
Best Regards,
LA-CO team

**Q: Can someone check the back label, does it have ingredients list? Specifically, would like to know if there is silicone in it.**
A: No ingredients list. Does not specify anything besides containing PTFE. SDS mentions only titanium dioxide. OK for potable water.
