Not sure why this is popping into my head right before I sleep, but what do you guys use to seal conduit when it comes out of s structure below grade. Example: Running 1" pvc/emt out of a basement to a shed. Duck seal? Fire caulk? Silicone?

Are you trying to seal the inside of the conduit or around the outside of it? Here's the links for Backstay and Jlarson's posts:

Here's for inside:

Here's for outside:

The ONLY long term protection from conduit sealing for me would be

DUCTOLOX 431

I have used it on interior and exterior of conduits with great results because it is Hydrophilic. It used water to cure. Funny product but works.

Linkseal is great too but not in all sitautions.
