Leak Check

How do you check if a used regulator is good or bad without any fittings attach to it yet? (No solenoid, no metering valve, no brass/ stainless steel fittings, Nothing!).

This is particularly when someone buys a used regulator on e-b-a-y that has not been tested to be working or not. So, it can be returned within time period specified by the seller.
