WashJet MEG 15015 Spray Nozzle 1/4" MNPT 15° SS - 2502

High-Impact Cleaning Power with Precise Flat Spray Control

The WashJet MEG 15015 is a flat spray nozzle from Spraying Systems Co., built for high-pressure cleaning tasks that demand both force and precision. It features a 15° flat spray angle, a size 15 orifice, and hardened stainless steel construction, all housed in a compact body with a 1/4 inch male NPT connection.

This nozzle produces a narrow, fan-shaped spray pattern that concentrates energy across a defined strip, removing grease, mud, rust, and baked-on residues in fewer passes than wider-angle tips allow. The hardened stainless steel body holds orifice dimensions stable under sustained use, so flow control accuracy and impact remain consistent shift after shift.

WashJet nozzles are ideal for pressure washing applications across industrial pressure washers, car wash facilities, heavy equipment cleaning, and plant maintenance lines where spray bars or manifolds require reliable, repeatable nozzle performance.

Why You'll Love the WashJet MEG 15015

Operators face the same set of problems repeatedly: stubborn residues that resist wide-angle rinsing, surfaces damaged by high impact solid stream tips, and nozzles that wear out and throw off cleaning schedules. The MEG 15015 addresses each of these directly.

• Consistent, High-Impact Cleaning – The 15° flat spray with size 15 orifice delivers a focused impact band that strips grease, mud, and baked-on material. An internal guide vane stabilizes liquid flow and reduces turbulence, keeping the spray coherent from center to edge. WashJet nozzles provide high-impact sprays with uniform distribution across the full fan width.

• Better Coverage with Fewer Passes – Compared to a 0° solid stream, the 15° fan covers a wider strip at working distance (typically 12 to 18 inches), which reduces the number of passes an operator needs. That translates to more cleaned area per hour and less physical fatigue.

• Reduced Downtime – WashJet nozzles are constructed from hardened stainless steel. The material resists erosion from high-pressure water, grit, and common wash chemicals, holding the orifice to spec across thousands of operating hours. Longer wear life means fewer tip replacements and fewer interruptions.

• Protects Sensitive Surfaces – The controlled 15° fan angle spreads force across a band rather than concentrating it in a point. That makes it safer for coatings, paint, seals, and glass than a 0° stream, provided the operator maintains proper standoff distance.

• Easy to Swap and Standardize – WashJet nozzles have a 1/4 inch male NPT connection that fits standard MEG holders and manifolds. Operators can swap between spray angles and orifice sizes without changing holders, making it straightforward to standardize across multiple wash stations.

What Makes the MEG 15015 Different

Generic pressure-washer tips often use softer metals and less precise orifice machining. After a few hundred hours of use, their spray angle widens, fan edges become ragged, and flow rate drifts above spec. Cleaning becomes uneven, and operators compensate by slowing down or increasing pressure, both of which waste time and accelerate equipment wear.

The MEG 15015 from Spraying Systems is built differently.

Precision-Machined Size 15 Orifice. The "015" designation refers to a specific orifice cross-section calibrated for predictable flow at a given pressure. At 40 psi, the size 15 orifice delivers approximately 1.5 gpm; at 1,000 psi, output scales to roughly 7.5 gpm. Because the orifice is machined to tight tolerances in hardened steel, flow control accuracy stays within spec over extended service.

True 15° Flat Spray Pattern. The nozzle uses a U-shaped orifice outlet paired with an internal guide vane to produce a well-defined flat fan. Spray angle of 15° produces a narrow flat-fan spray pattern that holds its shape reliably above 300 psi. Below that threshold, the fan may narrow or lose edge definition.

Hardened Stainless Steel Body. The body is 404-series hardened stainless steel with hex flats of approximately 9/16 inch and an overall length of about 1 inch. Weight is roughly 0.8 oz. This material resists corrosion, abrasion, and chemical attack under continuous duty.

Optimized for High Pressure Systems. The operating pressure range for this nozzle is 40 to 3,000 psi, and WashJet nozzles are rated for pressures up to 4000 PSI depending on the variant. WashJet nozzles operate effectively at pressures above 300 psi, where the flat spray pattern reaches full uniformity. The device is designed for optimal pressure-to-flow efficiency under high-pressure use.

Compatible with MEG Spray Rails and Manifolds. The MEG format fits standard spray bars used in conveyor and tunnel wash systems. Multiple MEG 15015 nozzles can be mounted in a rail, and because the full MEG series shares the same thread and body dimensions, operators can reconfigure spray angles or orifice sizes without replacing the manifold.

How the WashJet MEG 15015 Works

Pressurized water enters the nozzle, accelerates through a fixed orifice, and exits as a flat, fan-shaped jet. Here is what happens at each stage.

1. Pressurized Flow Enters the Nozzle Water from a high-pressure pump feeds into the rear of the nozzle through its 1/4 inch male NPT inlet. A fine mesh filter upstream is recommended to keep grit out of the orifice and protect the hardened stainless steel from unnecessary abrasion.

2. Water Accelerates Through Size 15 Orifice The orifice has a fixed cross-section, so as pump pressure increases, flow rate increases proportionally to the square root of pressure. Liquid flow rate ranges from 1.5 GPM to 13 GPM depending on operating pressures. The hardened steel preserves the orifice diameter, keeping that relationship stable over time.

3. Jet Forms a 15° Flat Fan Pattern The internal guide vane straightens the flow before it reaches the U-shaped outlet. The outlet geometry converts the round stream into a uniform flat fan spanning 15°. Edge-to-edge impact distribution reaches its best consistency at operating pressures above 300 psi (20 to 275 bar).

4. Impact Breaks Contaminants Free The concentrated energy of the flat fan breaks the adhesion between contaminants and the surface. Loosened material is swept away by the rinse flow. The fan shape distributes force across a strip rather than a point, reducing the risk of gouging while still delivering the high impact needed for heavy soils.

Who the WashJet MEG 15015 Is For

This nozzle is built for professional and industrial users who need repeatable cleaning results without risking surface damage or frequent tip changes.

Industrial Maintenance Teams clean plant floors, tanks, weldments, and steel structures where grease, scale, and rust accumulate under heavy production cycles. The MEG 15015 delivers the impact needed to clear those deposits during maintenance windows. The WashJet MEG 15015 is commonly used in industrial cleaning and equipment washdown across food processing, mining, and manufacturing facilities.

Fleet and Equipment Wash Operators handle trucks, buses, farm machinery, and construction equipment caked in mud, asphalt, and field dirt. A 15° fan hits door edges, wheel wells, and undercarriages with concentrated force that wider spray angles cannot match.

Automated Conveyor and Tunnel Wash Systems use spray bars with multiple nozzles mounted in sequence. The MEG 15015 fits standard MEG manifolds, so each nozzle in the rail delivers a consistent flat spray pattern across crates, containers, or component parts moving through the wash zone.

Professional Pressure-Washing Contractors clean building facades, loading docks, drive-throughs, and production floors. The controlled 15° fan removes contaminants without blasting off mortar, paint, or trim, which is critical when working on client property.

If you need strong yet controlled impact with a narrow fan for targeted cleaning applications, the MEG washjet 15015 fits that requirement.

Frequently Asked Questions

Below are answers to the most common questions about selecting, using, and maintaining the WashJet MEG 15015.

Is the MEG 15015 easy to install? Yes. It threads into any compatible MEG holder or manifold using its 1/4 inch male NPT connection. Apply PTFE tape or a sealant rated for high-pressure use, torque to spec, and confirm that the flat fan plane is oriented perpendicular to the direction of travel so the spray covers the intended strip.

What pressure range is recommended? The nozzle forms a spray pattern starting at 40 psi and operates up to 3,000 psi (with certain variants rated to 4,000 psi). For uniform edge-to-edge distribution, run the nozzle above 300 psi. Below that, the fan edges may lose definition.

Can I use chemicals with this nozzle? Stainless steel resists many common cleaning chemicals, including mild acids, alkalis, detergents, and sanitizers. Harsh oxidizers or high-concentration chlorine solutions can cause pitting over time. Rinse promptly after chemical use and verify compatibility with the chemical manufacturer.

How do I know when the nozzle is worn out? Check for four indicators: spray angle wider than the nominal 15°, uneven or ragged fan edges, reduced cleaning impact at the same pressure, and flow rate higher than expected (which signals the orifice has eroded). Any of these means the orifice has worn past its working tolerance.

What maintenance does the MEG 15015 require? Install fine filtration upstream to prevent grit from reaching the orifice. Periodically inspect the orifice for pitting or edge rounding. Clear debris with an appropriately sized probe; avoid oversized tools that can damage the orifice rim. Replace the nozzle when inspection reveals wear or when cleaning performance drops.

Can I replace other MEG nozzles with the 15015? Yes, as long as the replacement matches your system's flow rate, pressure, and spray angle requirements. Swapping from a smaller orifice (such as a size 6) to a size 15 increases flow, so confirm that your pump can supply the additional volume without dropping below target pressure. Check that downstream plumbing and chemical injection timing remain appropriate for the new flow rate.
