any recommendations on sealant to use on service entrance conduit fittings

I agree about the duct seal and I have looked into using a Dow spray foam product. I contacted Dow and they basically said their products have not been tested and are not listed for that use.If you are talking about around the conductors inside the conduit, I recommend duct seal #31-601 or equal. I have seen spray foam, and that is probably not illegal, but I haven't done any research to find out if it has deleterious affect on the wire insulation. I prefer the duct seal because it comes back out easier.

Actually I don't think duct seal is specifically listed for the purpose either.Isn't that the problem with using just about anything other than duct seal?
Did they offer to send you backup to their claim?I had an email exchange with one of the expanding foam people once. they claimed their product had been tested and did not have any deleterious effects on wire insulation.

When I looked into duct seal before I found it was for dry locations only.
I guess from the inside of the building?

Note the 'not for use outdoors' line.
I was pretty surprised to learn that as we always used it outdoors.
Well OK, looks like we're talking about two different products. The one I'm looking at was from Ideal and is the product mentioned at #2.
