Pfister PFAST Connectors
Author: elgato (AZ) Most of the Pfister faucets have an odd connector for the supply lines. They call it Pfast. Odd little push connector with 2 O rings. Does not look super reliable. Anyone have experience with these? Do you put al bit of silicone on the O rings?

I would have concerns if the connectors were on the hot and cold supply lines to the faucet. They are not on the supply lines but on the interconnecting hoses.
Two factors to be considered. They are not under much pressure, maybe 20 psi. Secondly they will not leak if the faucet is not turned on by somebody standing at the sink, who would presumably see the leak and turn the faucet off.
No different from the widely used connectors on kitchen pull out/pull down faucets. Those have been used for a long time without reports of them coming apart.
So, to answer your question, no, no concerns at all.
It is good practice to use silicone grease but I will confess I don't always do it.

Author: DaveMill (CA) I've encountered those on two faucets. The ceramic cartridge on both faucets needed replacement; those connectors were doing fine.
