Description Specs & Engineering Applications

The Standard for Surface Cleaners | 1/8" Configuration

The Spraying Systems WashJet® 1/8" MEG 25° Nozzle is an excellent industry standard option for Mosmatic and other premium surface cleaners. It provides the optimal balance between impact pressure and coverage area, ensuring a uniform clean without "tiger striping."

⚠️ Check Your Threads: 1/8" NPT

Small Thread Warning. This 1/8" NPT thread is designed for spinner arms and specialty lances. It will NOT fit standard 1/4" pressure washer wands.

✅ The WashJet® Advantage

Constructed from Hardened 404 Stainless Steel, this nozzle resists both high-pressure erosion (crucial for surface cleaners) and chemical corrosion. This ensures your fan pattern remains tight and consistent long after standard stainless tips have washed out.

Professional 1/8" 25° Use Cases:

Surface Cleaners (Mosmatic): The 25° spray pattern is an excellent option for Mosmatic and other premium 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.

💧 Installation Tip

Because 1/8" threads are smaller and often subjected to high vibration (or heat), Thread Tape (Teflon) or a medium-strength threadlocker (Blue Loctite) is highly recommended to prevent seizing or loosening during operation.
