Propane adapters used at an RV cylinder are not the same as the low-pressure quick-connect fittings used by an exterior BBQ. A cylinder-side fitting might involve a POL connector, a Type I/QCC (ACME) connector, a 1-inch-20 disposable-cylinder thread, or a separate pipe-thread connection. This illustrated parts reference helps you identify the connection family and compare exact manufacturer numbers.
Three common cylinder-side adapter families
POL to Type I/QCC
POL to pipe thread
POL to 1-inch-20 accessory

Flame King POL01JT002 is specifically described by Flame King as a POL-to-QCC1 Type I adapter. JR Products 07-30125 similarly connects male POL to a female quick cylinder connection. Marshall ME398P is its packaged quick-closing Type I adapter with a male soft-nose POL inlet and an ACME/Female POL outlet.
How to read a fitting with several ports
Portable-appliance tees can include connections that look similar in photos but serve different functions. JR Products 07-30135 includes a male POL inlet, female POL pass-through, 1-inch-20 male cylinder thread and 1/4-inch female inverted-flare connection. The 07-30165 is a simpler POL-to-1-inch-20 adapter with a handwheel.
The Marshall Excelsior ME423P is a 90-degree camping elbow with a POL cylinder connection, ACME pass-through and 1-inch-20 male accessory outlet. It should not be mistaken for a simple POL-to-QCC conversion fitting. Products in this category have model-specific shutoffs and pressure requirements; do not substitute one multiport fitting for another by appearance.
For a replacement, record every male/female connector type, the precise thread designation, whether a pressure regulator is upstream or downstream, and the cylinder and appliance manufacturer's model. The names POL, QCC1, NPT and 1-inch-20 describe different interfaces.
