I will say, If you defy the listing and directly glue the Carflex in an FS box, continue your defiance and use primer. I know from "spaflex", the white equivalent, Pool installers will tell you the primer is as important as the cement. Most inspectors I know would question that installation tho. As "crappy" as the Carlon connector might be, it is the only listed solution. It should be noted that Carlon does say you can direct glue ENT in their boxes and fittings. I was surprised when I read that in light of the Carflex thing.

Here's NEMA's take on the use of primer: http://www.udevices.com/pdf/solvent.pdf Electrical PVC cement comes in 3 flavors; Regular, Medium, and Heavy Bodied. The Heavy Bodied cement is recommended for larger pipe sizes, it has a longer cure time (hence more time to fit the conduit), and easier fills the voids between the socket and the conduit. _______________________________________________________________________________ I've tried all kinds of primer/glue combinations with Carflex, always with unsatisfactory results. The glue just doesn't stick to the Carflex. I guess that's why the make the cheap plastic fittings.

NEMA seems to be saying PVC cement is a generic product regulated by ASTM D 2564. Selection of Solvent Cement Solvent cements intended for use with PVC conduit and duct should meet all the applicable requirements of ASTM D 2564, “Solvent Cements for Poly(Vinyl Chloride) (PVC) Plastic Piping Systems.” Since they are available in a wide range of viscosities and wet film thicknesses, the nature of the particular project must be considered when trying to decide between a regular, medium, or heavy-bodied cement.

Here comes another question. If Cement is Cement, how about the 10 second blue?

I did get off subject. My bad. I don not use primer. I clean the pipe if needed then a generous amount of glue on both pieces and do a little twist when putting them together.

" the nature of the particular project must be considered"
Everyone likes to hear that they're right, but I never expected NEMA to state exactly what I did in my earlier post!
As for connecting the plastic flex directly to b oxes, etc., without using connectors, I vaguely recall reading a UL statement somewhere -perhaps UL "Question Corner" in the IAEI magazine?- that the stuff was listed for connecting that way. I was surprised when I read that, as not using a connector seems to go against everything I've ever done with other wiring methods.
I must object to the very idea that doing something with "brand A" might be OK, but not with "brand B." Life is complicated enough without opening the door to THAT form of BS- especially when you consider the plain illiteracy of so much that's printed.
I recall an ad campaign where the voice-over asserted that 'the eggs are from real chickens, the juice from real oranges, and the sausage is from Jimmy Dean.' Really? With all the sausage made, Jimmy must have been one very large man! Sort of puts "Girl Scout Cookies" in a new light too, but I wonder .....

Electrical PVC cement comes in 3 flavors; Regular, Medium, and Heavy Bodied. with a smokey oak bouquet.......?seriously, here's a consideration..... UG installs here are expected to leak , thus the URD, or TH WN , rated for wet location wire so.....for the part of UG installs exclusively underground , why glue anything underground at all?~S~

"Leak"? maybe but you don't want it to pull apart.
