GLADIATOR 1/4" MPT 25° 4.0 Pressure Washer Nozzle

Professional-Grade Nozzle for High-Flow Cleaning Systems

The 1/4" MPT 2504 Pressure Washer Nozzle is a precision-engineered spray tip built for high-performance cleaning applications. Designed to fit standard 1/4-inch MPT (Male Pipe Thread) connections, this nozzle delivers a 25° spray angle with a 0.04 orifice size — making it the perfect choice for use in high-flow systems and spray bars.

In fact, this nozzle is commonly used in the GP 1/4 MPT 25040 spray nozzle configuration, specifically designed for the 8 GPM, 4,000 PSI two-nozzle spray bar. That combination of flow and pressure provides the raw cleaning power needed for tough, large-scale cleaning jobs across industrial, agricultural, and commercial environments.

Durable, efficient, and purpose-built, the 2504 Nozzle is trusted by professionals who demand consistent performance day after day.

Designed for Spray Bars and High-Flow Applications

The 2504 nozzle is a perfect fit for spray bar setups, where consistent, high-volume cleaning power is required.

• Common Use: Specifically engineered for use with the 8 GPM, 4,000 PSI two-nozzle spray bar.

• Balanced Design: The 25° spray angle provides ideal coverage while maintaining concentrated cleaning force.

• Efficient Cleaning: Paired nozzles in a spray bar deliver high impact across wide surfaces for maximum productivity.

This setup is a staple for contractors and facility operators who need to clean large areas of concrete, fleets of vehicles, or heavy industrial equipment quickly and effectively.

1/4" MPT Connection for Secure Fit

Unlike quick connect nozzles, the 2504 Nozzle uses a 1/4-inch Male Pipe Thread (MPT) connection. This threaded style is commonly used in spray bars and specialized equipment because it ensures:

• Permanent Installation: Once tightened, the nozzle remains securely in place.

• Durability: Threads provide a solid, vibration-resistant fit.

• Compatibility: Fits standard 1/4-inch threaded ports used across pressure washer bars, manifolds, and custom rigs.

The MPT connection ensures reliability in high-pressure, high-flow environments where equipment is used continuously.

25° Spray Angle for Balanced Cleaning

The 25-degree spray pattern is one of the most versatile options available. It offers a medium-width fan that balances impact with coverage, making it the go-to choice for general cleaning.

Key applications include:

• Concrete Cleaning: Driveways, sidewalks, and parking lots.

• Fleet Washing: Trucks, trailers, and buses.

• Agricultural Equipment: Tractors, plows, and harvesters.

• Industrial Machinery: Construction and factory equipment.

• Facilities Maintenance: Large outdoor areas, warehouses, and loading bays.

In spray bar applications, the 25° angle ensures even coverage while maintaining enough impact force to strip away dirt, grease, and stains.

Precision Orifice Size – 0.04 Inches

The 0.04-inch orifice diameter is engineered to balance flow and pressure for optimal cleaning. In an 8 GPM, 4,000 PSI spray bar, two nozzles with this orifice size work together to maximize cleaning efficiency:

• Efficient Water Use: Properly matched orifice ensures pressure washer pumps are not overloaded.

• Consistent Spray Pattern: Maintains reliable fan distribution over time.

• High Flow Capability: Built to handle the demands of large-volume cleaning.

Correct orifice sizing is critical to performance, and the 2504 Nozzle delivers exactly what high-flow applications require.

Rugged, Professional Construction

The 1/4" MPT 2504 Nozzle is designed for longevity and reliability in demanding environments:

• High-Quality Materials: Built to withstand abrasion and erosion from high-pressure water.

• Corrosion Resistance: Suitable for use in wet, outdoor conditions.

• Long Service Life: Maintains spray accuracy over extended periods of use.

• Professional-Grade Manufacturing: Trusted by contractors, fleet operators, and facility managers worldwide.

This isn’t just a disposable tip — it’s a long-lasting tool built for professional pressure washing setups.

GP 1/4 MPT 25040 Spray Nozzle Setup

The GP 1/4 MPT 25040 spray nozzle setup is one of the most common configurations for spray bars. The 2504 nozzle plays a crucial role in this system:

• Used in Pairs: Typically, two nozzles are installed in the spray bar to balance flow and pressure.

• 8 GPM / 4,000 PSI: Provides a high-powered combination for large-scale cleaning.

• Even Coverage: Dual nozzles distribute water evenly across wide areas for faster results.

When combined, this system delivers the raw power required for demanding industrial cleaning jobs, making the 2504 nozzle an essential component.

Key Features

• Model: 1/4" MPT 2504 Pressure Washer Nozzle

• Connection Type: 1/4" MPT (Male Pipe Thread)

• Spray Angle: 25° medium fan pattern

• Orifice Diameter: 0.04 inches

• Maximum Pressure: 4,000 PSI (commonly paired with 8 GPM systems)

• Material: High-quality, erosion-resistant construction

• Application: Designed for spray bars, manifolds, and high-flow cleaning systems

Why Choose a 25° Spray Nozzle?

Every spray angle has its purpose. The 25° green nozzle is often considered the best all-around option because it:

• Provides more cleaning impact than a 40° nozzle.

• Covers wider areas than 0° and 15° nozzles.

• Works well on hard surfaces like concrete, brick, and stone.

• Is safe enough for painted and metal surfaces when used at proper distance.

When you want versatility without compromising power, the 25° nozzle is the right choice.

Comparison to Other Spray Patterns

To understand where the 2504 Nozzle fits, here’s how spray angles compare:

• Red (0°): Pinpoint, maximum impact, very high risk of surface damage.

• Yellow (15°): Narrow fan, aggressive cleaning, good for stripping paint or caked-on grime.

• Green (25°): Balanced spray, versatile, general-purpose cleaning.

• White (40°): Wide spray, gentlest impact, used for siding, vehicles, and delicate surfaces.

• Black (Soap): Low pressure, designed for chemical application.

The green 25° nozzle offers the most balanced cleaning power, making it indispensable in nearly every pressure washing setup.

Applications Across Industries

The 1/4" MPT 2504 Nozzle is trusted in a variety of industries where high-flow cleaning is essential:

• Construction: Concrete cleanup, equipment washing, surface prep.

• Transportation: Fleet maintenance for trucks, buses, and trailers.

• Agriculture: Heavy-duty washing of farm machinery and livestock areas.

• Manufacturing & Industrial: Cleaning equipment, factory floors, and loading bays.

• Municipal & Public Works: Large-scale cleaning of sidewalks, streets, and facilities.

Its rugged build and compatibility with spray bar systems make it especially popular among professional cleaning contractors.

Safety Considerations

As with all high-pressure cleaning equipment, the 2504 Nozzle must be used with care:

• Always test on a small area before cleaning softer materials.

• Keep the spray moving to avoid surface etching.

• Wear protective equipment, including gloves and safety glasses.

• Maintain a safe distance from people, pets, and windows.

• Verify compatibility with your system’s flow and pressure ratings.

When used properly, the nozzle delivers outstanding results without risking damage.
