Earlydean- While I support you professionalism and if I were installing the job I would not use chase nipples as this thread discribed them being used nor would I use reducing washers except where I had to for some unknown reason. While there are code reasons to not use these items for Service raceway bonding or over 250v. to ground, etc. the use of reducing washers and chase nipples is a code compliant installation and as an inspector we usually accept them when installed correctly.
