Interesting Question from an Engineer

Mike,

I’d like to ask your opinion on compression couplings versus set screw type. I work for an A & E firm and have been an electric power engineer for 48 years, and counting.  Our company standards call for compression couplings exclusively and have for as long as I know.

 

However, contractors who I respect for their experience and integrity (which is not all of them) state that set screw fittings are equal and in some ways better than compression.  And I think I agree, at least do not disagree, as I do not and never have regarded conduits as grounds. That being the case, I see little reason for compression couplings in most of our projects which are not in areas of high vibration, long vertical runs, long distanced between supports, conduit abuse, etc.

 

Your thoughts would be welcome.

 

Thanks, Kevin Cassidy

 

Mike Holt’s Response: Kevin, I never could figure out why compression fittings were part of specifications; to me SS fitting are equal to or better than compression fittings.

  • Hi Kevin you are right, it just depends on the contract, I work for the Government and their specifications state all compression connectors, compession connectors if tightened correctly will not open where set screws can. Also compession conectors can seal out water, it just depends on your use and their specs, I guess your company like the State Department has standards, and that way they keep every thing on same page...I Personally I would love to use a 4Inch set screw than a 4 Inch Compression, but that is not the specs.....
