Yah they are just pvc electrical conduit. It is the exact same as normal white PVC except it has UV protection added thus the gray color. I have been using them on tanks for a while. It really helps quiet things down since you don't have the hard 90 at the end of the stand pipe. You could also use Flex PVC but it is more costly and can be a challenge to glue unless you use the right glue.
