sorry got to agree with dave PTFE not needed with any hoselock fittings.....
don't buy cheap hoselock-type fittings make sure they are hoselock branded, or get rectus 26 - which is what i do,
if you do this but a pair of pinch pliars and a vast amount of "o" clips from e-bay seller circuit-hydraulics-LTD, great price and service.
infact thinking back to the early years! wish some one gave me this advice sooner!
