AL15-3/8 Trigger Spray Gun 4000 PSI | 3/8″ NPT F

AL15-3/8 Trigger Spray Gun 4000 PSI | 3/8″ NPT F

The AL15-3/8 is a high-performance
15° stainless-steel spray nozzle designed for
commercial and industrial pressure washer systems using
3/8″ quick-connect or threaded lance outlets.
Built for operators who need a balanced blend of cutting power and
surface coverage, the 15° spray angle delivers deeper penetration than
25° fan tips while still providing enough width to maintain
productivity in large cleaning areas.

Manufactured from precision-machined stainless steel, the
AL15-3/8 withstands high pressures, hot water, and abrasive cleaning
environments. This nozzle is ideal for contractors, facility maintenance
teams, heavy-equipment operators, and industrial wash crews who need a
durable, dependable spray pattern for daily work.

Design & Spray Characteristics

15° Medium-Impact Spray Pattern

• 15° fan angle provides a tighter pattern than 25° or 40° tips, offering improved penetration on tough deposits.
• Ideal for removing mud, grease, heavy films, tire marks, scale, and oxidation.
• Efficient for cleaning vertical surfaces where overspray needs to be controlled.
• Offers a strong middle ground between aggressive 0° tips and wider rinsing tips.

Stainless-Steel Body

• Machined from solid stainless steel for maximum durability and corrosion resistance.
• Handles hot-water systems and chemical detergents used in industrial cleaning.
• Resists deformation, ensuring a consistent spray pattern over the life of the nozzle.
• Excellent for harsh environments such as trucking yards, agriculture sites, and industrial facilities.

Applications & Use Cases

Commercial Pressure Washing

• Concrete and sidewalk cleaning where stubborn buildup must be broken apart.
• Building exteriors including block, stucco, masonry, and metal siding.
• Parking lots and garages removing oil stains, rubber marks, and layered grime.
• Construction cleanup including equipment, scaffolding, and forms.

Industrial Cleaning & Facilities

• Manufacturing plants dealing with grease, dust, and production residue.
• Food plant washdown where stainless steel is required for sanitation compatibility.
• Mining, aggregate, and heavy industry removing compacted soil, slurry, and abrasive residues.
• Fleet washing for trucks, buses, trailers, agricultural machinery, and utility vehicles.

Agriculture, Transport & Municipal Work

• Farm equipment washdown to remove mud and buildup from tractors, harvesters, and implements.
• Public works operations needing a dependable nozzle for sidewalks, road signs, and facility maintenance.
• Marine and boat maintenance when stainless resistance to corrosion is essential.

Installation & Compatibility

Connecting the Nozzle

• Fits 3/8″ high-pressure lances or quick-coupler adapters depending on configuration.
• Ensure the nozzle size (orifice number) matches your system’s GPM and PSI for optimal performance.
• Works with most commercial cold-water and hot-water pressure washer brands.
• Pair with a properly sized wand extension for improved control and safety.

System Considerations

• Using an incorrect orifice size can cause pressure loss or engine overload—match to your pump rating.
• Always verify compatibility with unloaders, hoses, and quick-couplers.
• Use PTFE thread sealant when installing on NPT-style fittings.

Ensuring Long Nozzle Life

• Rinse the nozzle with clean water after each use to remove grit that can erode the orifice.
• Check spray pattern periodically—distorted or uneven spray indicates wear.
• Replace nozzle at regular intervals to maintain proper GPM, PSI, and cleaning performance.
• Inspect stainless steel housing for signs of impact damage from drops or misuse.
• Store in a dry, protected accessory case to prevent contamination and clogging.
