Precision Engineered for Maximum Performance

The Spraying Systems WashJet® 0° MEG Nozzle is the industry benchmark for high-pressure fluid dynamics. While generic nozzles often suffer from rapid orifice erosion and spray pattern degradation, WashJet nozzles are manufactured to exacting tolerances to ensure consistent performance over a longer lifespan.

The result is a 0° solid stream with unrivaled cohesion. The precision-machined orifice creates a tighter water column that travels further and hits with greater impact density, making this the premium choice for critical hydro-excavation and precision cutting tasks.

✅ 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 and chemical corrosion from softwash mixes (SH). This ensures your stream remains tight and cohesive long after standard stainless tips have washed out.

⚠️ 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.
  • 🟢 25° (Green): Flushing / Surface Cleaners / J-Rod Close Application.
  • 40° (White): Washing / Windows / Siding.

Professional 0° Use Cases:

  • Hydro-Excavation: The precision-machined orifice creates a solid stream that maintains density over distance, ensuring maximum ground penetration.
  • Heavy Equipment (Tracks): Ideal for surgical cleaning of tracks and undercarriages where you need to cut through clay without splashing surrounding areas.
  • Distance Cleaning: Superior stream cohesion allows you to clean soffits and peaks effectively from the ground without excessive misting.
