PVC flexible pipe and NEC

[stardog]

I have a short run in the attic where I plan to run PVC flexible pipe. I have 1" solid PVC conduit running from the panel box into the soffit, but due to the steep roof angle I am unable to continue the solid conduit to the nearby jbox, a distance of maybe 18". To protect the exposed THWN 12 AWG wiring I plan to use 1" flexible PVC pipe from the jbox over to the to the solid conduit inside the soffit, using standard schedule 40 connectors at both ends.

I am sure this is standard practice for short-distance, tight or hard to access spaces. However, reading the NEC I cannot locate any specific reference to using non-metallic flexible pipe, how it should be secured to framing members, allowable or forbidden uses, etc., etc. Can anyone confirm the application I am using it for meets current code? Tks for anyone's input.

The obvious product to use would be Electrical Nonmetallic Tubing, ENT, aka Smurf Tube. That's covered by NEC Article 362.

Thanks. I plan to go that route.
