LA-CO 42029 Slic-Tite is a USDA-authorized, PTFE-infused thread sealant paste designed for heavy-duty sealing across metal and plastic pipe threads. It withstands extreme temperatures from -50°F to 500°F and is compatible with a wide range of fluids including gases, steam, and oils. Its non-toxic, non-drying formula washes off easily, while the Brush-N-Cap jar ensures clean, precise application—making it the go-to choice for professionals demanding reliability and ease.

High quality pipe dope, smooth threading. Personally, I first tape, then dope with this. If you want to take joints apart at some point, this is it.

Used this brand since the 80's, the local vender doesn't sell it any more. Found it on... well you know this place.... I have taken pluming parts off that I have used this stuff on and 9 times out of 10 it comes off fairly easy, even if it has been years.

I use this for sealing piston liners in old tractor engines. It works well.
