Connect LFNC to rigid PVC without adding a box?

[Yankeefarmer]

I have searched and searched, and even gotten bad answers from AI. For an outdoor lighting installation, I am considering using a short length of PVC Liquid-Tite to connect to rigid PVC tubing. Nobody seems to make a solvent weld to LFNC fitting. Is the only code compliant method to transition through a box with male adapters, or is it permissible to use a solvent weld female connector for rigid with the LFNC?

I always used a female threaded/slip coupling on the PVC conduit "transitioning" to a liquid tight connector.

LFNC is just a sunlight resistant version of flexible PVC pipe. Like Spa-flex. It is solvent weldable (using ordinary schedule 40 or 80 fittings), but doesn't hold well with ordinary PVC cement. There are special elastomeric cements for it for water applications, but I can't say I've seen it with conduit systems.

That’s so obvious now that you mention it, yet I never thought of it!

You need to use a glue designed spas to make the connection. Their flexible tubing is basically the same.

Now I regret that I didn’t title this thread, “Is connecting LFNC to rigid PVC conduit via solvent welding a gray area?

Of course it's all gray. Unless you paint it.

And I suggest painting pvc conduit and fittings. It takes a beating in the sun.
