A nozzle is used in a hand held dispenser of viscous fluid including caulking, sealant or adhesive. The nozzle has an elongated body that extends along a longitudinal axis, defining a fluid path extending between a dispensing end and a base. The base includes a coupling to secure the nozzle to a dispensing device or to a container of the viscous fluid. The nozzle includes a variable flow valve that operates through a range of positions, between a fully closed position and a fully open position. The valve operates within a housing that extends across the longitudinal axis of the body. A second coupling connects the valve to a hand control on the dispenser. Preferably, the valve rotates between the closed and open positions. The nozzle is also included in a dispensing gun. The dispensing gun includes a hand activated control on the gun handle. The control operates the valve between the closed and open positions and co-acts to urge the fluid contents of the dispensing gun to flow through the nozzle. A kit for a nozzle assembly in a hand held dispenser includes the nozzle and a replaceable nozzle tip. The kit may also include one or more interchangeable nozzle tips, a replaceable end cap, and a cleaning tool for the nozzle.
