A few days ago I posted a question about testing conduit seals ( I have a separate question about conduit seals resulting from the same project referenced in that thread:
Is there a recommended method for removing conduit seals without damaging the conductors and introducing something into the conduit that could cause problems later?
I understand that chipping out the seals works but usually damages the insulation or conductors and almost always leads to repulling the wires.
I've heard about using vinegar (which I also found mentioned at This method could be slow and still require chipping, according to one electrician.
Finally, I've been told that Chico (not including SpeedSeal) is essentially plaster-of-Paris, though the MSDS ( says it is only about one-third p-o-P. A Google search resulted in a link to a site that discussed using "a dilute potassium acetate solution" to remove plaster from molds ( but I couldn't determine whether this would work with Chico.
I couldn't find anything in the literature on CCH's web site about seal removal. My question applies to conventional seals; it would appear to be essentially impossible to remove an epoxy SpeedSeal based on CCH's video and support documentation.
