asked by: DAVE
Expert Reply:
P.O.L is actually and abbreviation for Prest-O-Lite, for the company that first produced the valve.
This style of connector you will tighten the connector of the regulator pigtail by turning the fitting counter-clockwise, and you usually need to use a wrench to make the connection tight enough to prevent leaks. With the POL valve, if you open it with no fitting attached, propane is freely released. That's why a plug is required to be screwed into the valve during transport of the cylinder and when it is stored or not connected to your RV. The plug is an attempt to prevent an accidental opening of the valve from creating a dangerous situation. This valve also has a built-in bleeder valve the service technician uses to check for proper filling and a pressure relief device to prevent over pressurization of the cylinder.
