Adjustable Hose Nozzle

Prosser nozzles are lightweight Thermoplastic and under normal operating conditions of 83.6gpm @ 100 psi are very easy to handle. These nozzles were designed for the express use of firefighting with water. Thread is NPS. They may also be used for industrial washdown applications limited to water and a maximum of pressure of 100 psi. Use of other liquids can cause damage to the nozzles. All HN-1L and HN-4L models are Factory Mutual approved. 

The fire nozzle is an important part of the firefighting system. Nozzles are designed to help put out fires by getting the right amount of water, in the right form, in the right place. The solid or smooth bore nozzle is the most basic of the four nozzle types, both in design and function. Its purpose is to produce a solid stream, which provides maximum reach and penetration.

Nozzles have three main functions:

1. Control Flow
The size of the orifice in the outlet of the nozzle controls the flow.

2. Provide Reach
The nozzle creates a restriction at the end of the waterway, which changes water pressure to velocity. Velocity provides the reach, which is necessary to get the water to where it is needed.

3. Create Shape
Different situations require different methods of applying water. Some situations require the reach and penetration of a straight stream, while others require the wetting coverage or heat adsorption capability or radiant heat protection of a wide angle fog spray.
