GLADIATOR 1/4" MPT 0° 4.0 Pressure Washer Nozzle

Maximum Precision with a 0° Solid Stream

The 1/4" MPT 0004 Pressure Washer Nozzle is a high-performance spray tip engineered for extreme precision and concentrated cleaning power. Built with a 0° solid stream spray pattern, a 0.04-inch orifice size, and a secure 1/4-inch MPT (Male Pipe Thread) connection, this nozzle is the tool of choice for demanding jobs that require pinpoint accuracy and maximum impact.

Capable of delivering up to 4,000 PSI depending on system setup, this nozzle is designed for use in industrial cleaning, surface preparation, and specialized applications where other spray patterns simply don’t cut it. Whether it’s blasting through hardened debris, stripping rust from steel, or preparing concrete for coating, the 0004 nozzle provides unmatched cleaning power in the smallest footprint possible.

Designed for Maximum Impact

While wider spray angles (15°, 25°, and 40°) distribute water across larger areas, the 0° nozzle focuses all available pressure into a single solid stream. This design offers:

• Maximum Cutting Power: Concentrates cleaning energy into one narrow jet.

• Pinpoint Precision: Ideal for targeting stubborn spots that wider fans can’t touch.

• Material Removal Capability: Strong enough to strip paint, coatings, and rust.

• Specialized Applications: Best suited for industrial and heavy-duty environments.

With its extreme force, this nozzle should be used carefully. It’s designed for spot cleaning, not wide-area coverage.

1/4" MPT Threaded Connection

Unlike quick connect nozzles, the 1/4" MPT 0004 Nozzle uses a male pipe thread connection. This threaded style ensures:

• Secure Fit: Screws directly into spray bars, manifolds, or custom cleaning rigs.

• Durability: Stays firmly in place during continuous use, even under vibration.

• Industry Standard Size: Fits most threaded 1/4-inch MPT ports used in pressure washer equipment.

• Professional Preference: Favored in spray bar and multi-nozzle systems where permanent installation is required.

The threaded design makes this nozzle particularly useful in setups where reliability and consistency matter most.

0° Spray Pattern – The Red Nozzle

In the universal nozzle color coding system, red means 0° — the most powerful and precise spray angle available. This nozzle produces a straight, solid stream of water, offering the highest cleaning impact but the least coverage.

Common uses include:

• Stain Removal: Oil, grease, and graffiti on concrete or stone.

• Rust and Paint Removal: Stripping surfaces before refinishing.

• Surface Prep: Prepping steel and concrete for coatings or sealants.

• Industrial Cleaning: Removing baked-on residues, hardened grime, or adhesives.

• Agriculture & Construction: Cleaning heavy machinery and equipment with hardened buildup.

Because of its intensity, this nozzle should not be used on delicate materials such as siding, wood, or paint finishes unless removal is intentional.

Precision Orifice Size – 0.04 Inches

The 0.04-inch orifice is carefully matched to flow and pressure requirements for high-performance cleaning:

• Balanced Flow Rate: Ensures water output matches pump capacity.

• Pressure Efficiency: Maintains consistent system pressure without overloading pumps.

• Reliable Performance: Produces a stable, predictable stream for precise cleaning.

• Optimized for Power: Small orifice size channels maximum PSI into a pinpoint jet.

Selecting the right orifice size is critical in pressure washing. The 0004 nozzle is designed for use with medium- to high-pressure washers in the 4,000 PSI class, making it ideal for demanding applications.

Built for Industrial Environments

The 1/4" MPT 0004 Nozzle is constructed from durable materials to withstand high pressure, abrasive water flow, and continuous use:

• Corrosion Resistance: Suitable for wet, outdoor, and industrial environments.

• Wear Resistance: Designed to hold spray accuracy over extended use.

• Heavy-Duty Durability: Withstands the rigors of daily professional use.

• Precision Machining: Ensures consistent orifice size and spray performance.

This nozzle isn’t a light-duty accessory. It’s a professional tool built for extreme conditions.

Why Choose a 0° Nozzle?

While not suitable for every job, the 0° red nozzle is indispensable for certain applications:

• Toughest Stains: Oil, tar, rust, and graffiti that resist wider spray tips.

• Precision Work: Removing buildup from tight corners or crevices.

• Surface Prep: Stripping paint or coatings from small areas before refinishing.

• Industrial Cleaning: Targeting hardened deposits in factories or processing plants.

It’s a specialty tool — one you won’t use for everyday cleaning, but one you’ll be glad to have when nothing else works.

Comparison to Other Nozzles

Here’s how the 0004 Nozzle compares to its color-coded counterparts:

• Red (0°): Solid stream, maximum impact, minimal coverage.

• Yellow (15°): Narrow fan, excellent for heavy-duty cleaning.

• Green (25°): Balanced fan, the most versatile for general cleaning.

• White (40°): Wide fan, safe for delicate surfaces.

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

The 0004 nozzle delivers the highest intensity stream available. It’s not for every surface, but it’s irreplaceable for specialized cleaning needs.

Applications Across Industries

The 1/4" MPT 0004 Nozzle is used across many sectors:

• Construction: Removing concrete splatter, prepping surfaces for coating.

• Transportation: Stripping rust and grime from trucks, trailers, and equipment.

• Agriculture: Cleaning heavy farm machinery and industrial equipment.

• Industrial Manufacturing: Removing adhesives, coatings, and stubborn buildup.

• Municipal: Removing graffiti, gum, and tough stains from public spaces.

Wherever extreme cleaning power is required, the 0004 nozzle is the go-to solution.

Safety Considerations

Because of its extreme intensity, the 0° nozzle must be used with caution:

• Surface Damage: Can etch, gouge, or cut softer materials.

• Operator Safety: Always wear gloves, safety glasses, and protective clothing.

• Controlled Use: Keep the spray moving and avoid holding in one place too long.

• Safe Distance: Never point at people, pets, or fragile surfaces.

• Training Required: Best used by experienced operators who understand its power.

Used properly, it’s one of the most effective tools in professional cleaning.

Trusted by Professionals

The 1/4" MPT 0004 Pressure Washer Nozzle is trusted worldwide by contractors, industrial cleaners, and facility managers. Its combination of threaded reliability, 0° precision, and extreme power makes it an essential tool for specialized cleaning tasks.

While it’s not an everyday nozzle, it’s a must-have accessory for professionals who encounter the toughest cleaning challenges. When no other spray pattern is strong enough, the 0004 nozzle delivers the impact you need.
