QZ and Russian-pattern configurations

Straight-Stream Fire Hose Nozzles

Aluminium-alloy fire hose nozzles with a straight-stream jet. Choose a QZ configuration in DN50 or DN65, or a Russian-pattern configuration in 2 in or 2½ in.

Aluminium alloy DN50 / DN65 · 2 in / 2½ in 2 in / 2½ in

Nominal sizes identify the available selections. Confirm the exact inlet coupling and mating component before ordering.

Specifications

Available configurations and sizes

Both configurations have an aluminium-alloy body and a straight-stream jet. Confirm the final coupling specification with the quotation.
