No, they cannot be reused
PEX Sliding Fittings are designed for one-time use only. The sliding ring is permanently deformed during installation. The fitting itself is also permanently compressed. Example: a removed fitting must be discarded.
The ring is permanently deformed
The sliding ring is expanded and then contracted. This permanently changes the ring's shape. It cannot be reused on another pipe. PEX Sliding Fittings rings are single-use.
The pipe is compressed
The pipe is permanently compressed by the ring. This leaves a groove in the pipe. The pipe section must be cut off. PEX Sliding Fittings require fresh pipe for new connections.
Removal requires cutting
Removing a sliding fitting requires cutting. The pipe is cut on both sides of the fitting. The fitting is discarded. PEX Sliding Fittings are not designed to be removed intact.
Manufacturer recommendations
Manufacturers clearly state that fittings are single-use. Reusing fittings voids warranties. It is not recommended under any circumstances. PEX Sliding Fittings should always be new.
Example: attempted reuse
A plumber tries to reuse a sliding fitting. He removes it from an old pipe. He tries to slide it onto a new pipe. PEX Sliding Fittings do not seal properly. Example: the fitting leaks immediately.
Example: proper replacement
A fitting is removed from a system. The plumber cuts the pipe and discards the fitting. He installs a new sliding fitting. PEX Sliding Fittings are always replaced.
Cost vs. risk
A new fitting is inexpensive. A leak from a reused fitting can cause damage. Reusing fittings is not worth the risk. PEX Sliding Fittings should always be new.

Final reusability summary
PEX Sliding Fittings cannot be reused. The ring and pipe are permanently deformed. Removal requires cutting and replacement. Manufacturers prohibit reuse. Reused fittings will leak and fail.
