1. Brass

2. Plastic

3. Stainless Steel

4. All of the above

The correct answer is: All of the above

Nozzles can be constructed from a variety of materials, each chosen for its particular advantages, such as resistance to corrosion, durability, and cost-effectiveness. Brass is often used in nozzles due to its strength and resistance to wear, making it suitable for various spraying applications. Plastic is favored for its lightweight and cost-effective properties, and it provides good resistance to many chemicals, though it may not withstand high pressures as well as metal options. Stainless steel, known for its exceptional resistance to rust and corrosion, is ideal for applications involving aggressive chemicals, extending the nozzle's lifespan. Given that all these materials—brass, plastic, and stainless steel—can be effectively utilized to manufacture nozzles, the choice indicating that all of the above is accurate. Each material offers unique properties that can be beneficial in different scenarios, allowing for flexibility in choosing the right nozzle based on the specific needs of the pest control application.
