Re: CQD answer published Tuesday, April 16, 2019 -LFNC Connectors
Hi Charlie, I have been thinking about your answer to the connecter question and am wondering if this applies to electrical nonmetallic tubing also. Can fittings for PVC conduit be used with electrical nonmetallic tubing?
Thank you,

Answer:
Hey Erin thanks for your follow up question. Yes, PVC fittings can be used with electrical nonmetallic tubing (ENT). The information to support this can be found at:
http://productspec.ul.com/document.php?id=FKHU.GuideInfo
Fittings — The outside diameters of ENT are such that standard connectors, couplings and outlet boxes for rigid PVC conduit can be employed for ENT that is also constructed of PVC. Installation instructions are provided with each bundle or coil of ENT outlining the procedure to be used when employing cemented-on PVC conduit fittings and outlet boxes. These techniques include the specific cement to be used as well as its application method. Other fittings are covered under Electrical-nonmetallic-tubing Fittings (FKKY
There is no section 362.42 like there is a 356.42 which only allows fittings specifically listed for use with Liquidtight Flexible Nonmetallic Conduit (LFNC). Consider submitting a Public Input for the 2023 NEC to add wording that would specifically allow PVC fittings to be used with ENT.
