You mean of course that;
1) SCH 40 cleanouts exist, they are DWV only parts. The lower photo is a SCH 40 DWV cleanout.
2) In addition, there are SCH 40 pressure rated threaded components (the upper photo) that include threaded plugs.
I believe a "cleanout" is, by definition, a DWV only part since "cleanouts" aren't needed/used in PWS systems.
In other words, both of your photos are of SCH 40 parts. The lower one is a DWV cleanout and is not pressure rated. The upper one is a threaded fitting with plug that is pressure rated. Technically, the upper one isn't a "cleanout", though it could be used as one.
EDIT: Tagged the photos backwards.
The bottom photo is not of a Schedule 40 part. The telltale sign is the length of the threaded portion is about 1/2 the diameter. It has a short threaded section and short glue section.
Cleanout plug has a short threaded section.
Schedule 40 plug has long threaded section.
Schedule 40 parts have deep sockets both for threaded parts and glue joints.
The Schedule 40 female adapter can be used for connection to threaded pipe, pumps, valves, or sealed with a plug.
