An adjustable nozzle is a type of nozzle that can be adjusted to create a variety of spray patterns. It is typically made of brass, SS or plastic and has a screw mechanism on the end. By turning the screw, the opening of the nozzle can be widened or narrowed, which changes the spray pattern. Some adjustable nozzles also have a lever or trigger that can be used to turn the water on and off.

Here are some of the common specifications of adjustable nozzles:

• Material: Brass, SS or plastic
• Size: The size of an adjustable nozzle is typically measured by the diameter of its opening. Common sizes include 1/2 inch, 3/4 inch, and 1 inch.
• Thread type: The thread type of an adjustable nozzle is the type of threads that are on the outside of the nozzle. Common thread types include NPT and GHT.
• Pressure rating: The pressure rating of an adjustable nozzle is the maximum amount of pressure that the nozzle can withstand. Pressure ratings are typically given in PSI (pounds per square inch).
• Flow rate: The flow rate of an adjustable nozzle is the amount of water that can flow through the nozzle in a given amount of time. Flow rates are typically given in GPM (gallons per minute).

When choosing an adjustable nozzle, it is important to consider the application for which it will be used. The size, thread type, pressure rating, and flow rate of the nozzle will all need to be compatible with the application.

Here are some additional things to keep in mind when choosing an adjustable nozzle:

• The spray pattern of the nozzle. Adjustable nozzles can create a variety of spray patterns, including mist, jet, and shower. Choose a spray pattern that is appropriate for the application.
• The durability of the nozzle. Adjustable nozzles are available in a variety of materials, including brass, plastic, and stainless steel. Choose a material that is durable enough for the application.
• The ease of use of the nozzle. Some adjustable nozzles are easier to use than others. Choose a nozzle that is easy to adjust and that has a comfortable grip.
