AL13-3/8 Zinc Trigger Spray Gun 3700 PSI | 3/8″ NPT

AL13-3/8 Zinc Trigger Spray Gun 3700 PSI | 3/8″ NPT

The AL13-3/8 Zinc Pressure Washer Trigger Control is a rugged, reliable spray gun designed for
operators who need dependable performance across a wide range of cleaning applications. Rated for up to
3,700 PSI, this trigger control strikes the ideal balance between heavy-duty capability and
user-friendly design. Built with a corrosion-resistant zinc housing, it offers superior durability compared to
standard trigger bodies, ensuring long service life even in demanding residential and commercial environments.

Outfitted with a 3/8″ NPT threaded inlet, the AL13-3/8 connects securely to most pressure
washer hoses and spray lances without the need for complex adapters. Precision-machined threading ensures a tight,
leak-free seal that maintains peak operating pressure, providing consistent water delivery and maximizing cleaning
efficiency. Whether blasting away grime on patios, restoring weathered decks, or supporting light industrial washing
tasks, the AL13-3/8 delivers consistent, professional results.

Performance & Power

3700 PSI Working Range

Rated for 3,700 PSI, the AL13-3/8 is engineered to handle medium- to heavy-duty jobs with ease.
This power range makes it versatile enough to be used in multiple settings:

• Residential: strips mold, mildew, and dirt from siding, fences, decks, and patios.
• Commercial maintenance: restores concrete walkways, storefronts, and driveways to a clean, professional appearance.
• Light industrial: supports machinery cleaning, workshop floors, and light equipment degreasing.

The zinc construction enhances structural strength, ensuring the trigger control can withstand repeated high-pressure
cycling without cracking or deforming. The internal valve system is optimized for smooth water delivery, minimizing
pulsing or pressure drop-offs that can compromise cleaning quality.

Construction & Durability

Zinc Body & Quality Assurance

The AL13-3/8 is built with a zinc body, chosen for its excellent corrosion resistance and
durability. Zinc is naturally resistant to rust, making this trigger control ideal for environments where exposure
to moisture, chemicals, or cleaning detergents is routine.

Each trigger undergoes factory testing before shipping, verifying its ability to maintain leak-free operation under
sustained pressure loads. Reinforced stress points resist deformation under heavy usage, extending service life and
reducing replacement frequency for contractors and facility managers.

Ergonomics & Operator Comfort

Comfort-Focused Design

Extended cleaning sessions can take a toll on operators, which is why the AL13-3/8 is designed with ergonomics in
mind. The comfort-shaped handle reduces strain on the hands and wrists, while the smooth trigger mechanism minimizes
the force required to engage or release the spray. These features make the spray gun comfortable for prolonged use,
even with gloves or in wet conditions.

The responsive trigger provides precise flow control, giving operators the ability to quickly transition between
high-pressure blasting for heavy soils and softer rinsing for delicate surfaces. This flexibility reduces fatigue
and increases overall efficiency during multi-step cleaning projects.

Compatibility & Ease of Use

3/8″ NPT Connection

Featuring a 3/8″ NPT threaded connection, the AL13-3/8 integrates seamlessly with most North
American pressure washer hoses and spray lances. This standard connection eliminates compatibility concerns,
allowing for fast installation and secure attachment.

The compact, balanced design makes it easy to maneuver, even in tight spaces or when working overhead. Operators
benefit from a tool that is both powerful and easy to control, ensuring precise cleaning results without unnecessary
strain.
