Description Specs & Engineering Applications

The Universal Standard: Precision Flushing & Surface Cleaning

The Spraying Systems WashJet® 25° MEG Nozzle is the premium upgrade for flat surface cleaners and general flushing. While generic nozzles suffer from spray pattern degradation (blurring edges), WashJet nozzles are engineered for Even-Edge distribution.

The 25° angle creates a wide, uniform "sheet" of water. This is the exact OEM replacement specification for Whirl-A-Way, General Pump Hammerhead, and Whisper Wash surface cleaners. The precision-machined orifice ensures a consistent overlap, helping to eliminate the "zebra striping" common with inferior tips.

✅ The WashJet® Advantage: 404 Series Steel

WashJet MEG nozzles are constructed from premium Hardened 404 Series Stainless Steel. This alloy is engineered to withstand the dual threat of high-pressure erosion (crucial for surface cleaners) and chemical corrosion from softwash mixes (SH). This ensures your fan pattern remains tight and consistent long after standard nozzles have failed.

⚠️ Precision Sizing Required

Selecting the wrong orifice size is the #1 cause of decreased performance.

Too Small: Your unloader valve will bypass water to limit pressure. This reduces the flow rate at the tip, killing your cleaning efficiency.
Too Big: System pressure drops drastically, significantly reducing your impact force and cleaning power.

Spray Angle Color Guide

Note: WashJet MEG nozzles are unpainted stainless steel. The list below references the matching Quick Connect industry standard colors.

🔴 0° (Red): Cutting / Hydro-Excavation / J-Rod High Reach.
🟡 15° (Yellow): Chiseling / Paint Stripping / Heavy Grease.
🟢 25° (Green): Flushing / Surface Cleaners / J-Rod Close Application.
⚪ 40° (White): Washing / Windows / Siding.

Professional 25° Use Cases:

Surface Cleaners (Whirl-A-Way): The 25° spray pattern is the industry standard for 90% of surface cleaners. It provides the optimal overlap for streak-free concrete cleaning.
General Washing: Ideal for rinsing soap off siding, cleaning decks, or washing vehicles. The fan is wide enough to be safe on most hard surfaces but concentrated enough to move debris.
Fleet Washing: The standard tip for pressure washer wands when cleaning trucks and heavy equipment, balancing coverage with impact.

💧 Softwash & J-Rod Sizing Guide

Because WashJet nozzles are available in the large Orifice Sizes required for J-Rods and nozzle holders, they serve dual purposes for Softwash and high pressure applications.

25° Tips are primarily used in pre-made J-Rod kits.

Your Machine	Standard Rinse Tip (High Pressure)	Standard Soap Tip (Low Pressure)
2 - 3 GPM	Size # 10.0	Size # 30.0
3.5 - 4.5 GPM	Size # 10.0	Size # 40.0
5 - 6.5 GPM	Size # 15.0	Size # 40.0
7 - 8.5 GPM	Size # 20.0	Size # 60.0

Note: Installing a #30 - #60 nozzle on a standard machine will drop pressure drastically, automatically engaging your downstream chemical injector.
