Hi,
Almost ALL hubs are the VERY same material as the offset nipple your talking about.
I do not know how many of these I have replaced due to cracks and breaks...that said I have NEVER seen a BROKEN offset nipple in my 27 years in the trade.
Can you PROVE that a die cast hub is four times or more stronger than another die cast part? Please do if you can, I have NEVER heard anything like that!
There may be steel hubs out there but that is a special order item not a standard issue.
I also beleive there are se offset nipples available for making that little offset you need to get over to the wall or to straighten the pipe. Most hubs will provide some movement for aligning..I use them all the time and have NEVER had a single problem.
there is no difference in using a die cast part on a service vs a die cast straight connector on emt that feeds anything else of that nature...xfmr, disco etc.
So do we now stop using die cast connectors and parts? NO!
which is stronger die cat or PVC? do we stop using pvc too?
if you want a rigid offset nipple because you are concerned then look at these:
