rubber couplings

[Scott.Fields]

i need to find out if a rubber type coupling that you usually see in plumbing applications on schedule 40 white pipe is acceptable for electrical applications. (listed under BOCA 8614)

No, it is not acceptable, see 352.6

Crouse Hines sell an Expansion/Deflection cplg,Type XD,and it appears to be a rubber cplg but it is Neoprene and has a plastic inner sleeve.I thought it was code compliant but it may have been done away with.
