Qest fittings

I have a Qest shutoff valve such as used for a lavatory faucet connection. I want to use it on a piece of cpvc. Proper sequence for assembly, nut on pipe, rubber bushing on next, metal push on ring next, then screw all to the valve??????? What is the right way?

nut - ring - bushing

And make sure the ring is on facing in the right direction.
