Brass fittings are for threaded joints: connecting a pump and pressure tank, filters, meters and valves. Brass does not rust and copes with hot water and heating.
The name gives the size and thread type: F for female, M for male. A threaded joint needs proper sealing so it does not leak — see “How to seal a threaded joint”.
