Description Specs & Engineering Applications

Wide Coverage Rinsing | 1/8" Configuration

The Spraying Systems WashJet® 1/8" MEG 40° Nozzle provides the widest coverage for rinsing and soft washing. It creates a "soft" fan pattern that maximizes coverage application efficieny time to the surface while minimizing impact pressure, making it safe for delicate substrates like wood, glass, or vehicle paint.

⚠️ Check Your Threads: 1/8" NPT

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

✅ The WashJet® Advantage

Constructed from Hardened 404 Stainless Steel, this nozzle resists the "washout" effect that widens the fan angle over time, ensuring your 40° pattern stays accurate.
