Pull elbows in walls

Are PVC pull elbows allowed inside walls? And if they are, must they remain accessible like J boxes? And if they must, can I use a piece of plywood with screws to make an access panel where the pull elbows are located? Thanks. John.

My take is, they are not junction boxes as you are not making a junction inside them. However, they have removable covers, which can be defined like a junction box and must remain accessible. Your idea of a panel cover is fine.

I agree, it will need to be accessible.

Conduit bodies are required to be accessible. The access panel option is OK.

Thanks guys. Next question. When terminating PVC into an outdoor panel, is there anything that is done to make the male terminal adapter waterproof? Maybe silicone? Or is there an O ring I can install? Thanks.

What type outdoor panel? You can't come from the top in most cases. Is it metal or pvc box? Is it a "panel" or a junction box?

It is a 16"X16"X6" PVC box with a gasketed screw on cover. It will be used to house the splices used to change conductor sizes.

I wouldn't enter the top either, but would enter the side. I don't think sealing is necessary, but if you want to you can use a flat sealing washer from Carlon.

Where a waterproof termination is required into any
enclosure (metallic or nonmetallic), install the neoprene
washer over the threads of a terminal adapter before
inserting into the enclosure. Use a standard locknut or
threaded bushing to secure the assembly.

I used Crouse-Hinds metal-banded conduit sealing washers for a similar application except with a metal box, but the already-linked is probably better for PVC to PVC.

FYI my metal Hoffman box replaced a plastic box that I had affixed too tightly to my brick wall. After a year of contraction and expansion all of the clamps holding the box to the wall were broken, as was the cover of the box and the box itself. So don't overdo it.
