ABSTRACT A three-piece nozzle is disclosed, for fitment to a hand actuated liquid pump having a barrel portion with a bore therethrough for passage of liquid. The nozzle features an integrally formed nozzle cap which fits around the end portion of the barrel. Enclosed within the nozzle cap is an integrally formed nozzle seal which forms a peripheral liquid-tight seal around the barrel between the nozzle cap and the barrel. Also provided is an integrally formed check valve which is movably positioned at the mouth of the bore and which is biased towards the mouth of the bore to form a liquid-tight bore seal. The bias is overcome, to open the liquid-tight bore seal, upon actuation of the pump which provides liquid pressure in the bore to act against the check valve.
