Conduit Seal (Chico) Removal
Conduit Seal (Chico) Removal
(OP)
A few days ago I posted a question about testing conduit seals (http://www.eng-tips.com/viewthread.cfm?qid=141712). 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 http://www.elec-toolbox.com/tricks/chico.htm). 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 (http: //www.crou se-hinds.c om/crouseh inds/resou rces/msds/ ms_chico_s ealing.cfm) 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 (http://www.plastermaster.com/usg/plaster201.htm) 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.

It was called a JetEtch.
It used boiling concentrated sulphuric acid...
Just a thought...
Scrap it & start again sounds reasonable to me...
