The question
Under 40 CFR 82.154(e), a new small appliance sold in the U.S. must come with what feature to make recovery possible?
- A pressure relief valve
- A sight glass
- A permanently attached recovery unit
- A process stubCorrect answer
Why “A process stub” is correct
New small appliances must have a process stub, a length of tubing that gives access to the refrigerant and can be resealed. Larger appliances must have a servicing aperture. Both make recovery at service and disposal possible.

Why the other answers are wrong
- A pressure relief valve — Relief valves protect against overpressure but are not the required access point.
- A sight glass — A sight glass shows liquid flow and is not required for recovery.
- A permanently attached recovery unit — Permanently attached recovery units are not required.
