Description Specs & Engineering Applications

Concentrated Scraper | Wet Sandblasting & Heavy Equipment

The Spraying Systems WashJet® 5° MEG Nozzle fills the gap between the 0° tip and the 15° tip.

This 5° spray angle creates a tightly concentrated stream with just enough spread to push heavy debris (like dried clay, concrete splatter, or chewing gum) out of the way as it cuts.

✅ The Ideal Wet Sandblasting Nozzle

Most wet sandblasting kits (injection heads) require a nozzle that creates high-velocity suction without cutting into the side of the mixing head. The 5° angle is the industry preference for these kits, offering better venturi performance than a 15° tip and less wear-and-tear than a 0° tip.

⚠️ Precision Sizing Required

Because this nozzle is designed for maximum impact, selecting the correct orifice size is critical.

Too Small: creates back-pressure that can damage your pump.

Too Big: reduces velocity, making sandblasting or scraping ineffective.

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.

🟠 5° (Specialty): Wet Sandblasting / Heavy Scraping.

🟡 15° (Yellow): Chiseling / Paint Stripping.

🟢 25° (Green): Flushing / Surface Cleaners.

⚪ 40° (White): Washing / Windows.

Professional 5° Use Cases:

Wet Sandblasting: The 5° angle creates the perfect balance of velocity and spread to create the venturi effect needed for injection heads without cutting the nozzle holder.

Concrete Scraping: Ideal for removing chewing gum, tar, or heavy grease spots where a 15° tip is too weak but a 0° tip is too narrow.

Heavy Equipment: Perfect for knocking thick chunks of dried clay and mud off excavator tracks and undercarriages.

⚠️ Surface Safety Warning

This nozzle provides extremely high impact density. Do not use on wood, vinyl siding, vehicles, or soft stone. It will etch concrete and strip paint almost instantly.
