MTM Hydro Acqualine Stainless Steel Pressure Washer Nozzle Tip — 40° 4.0 with Rubber Guard, 1/4" Quick-Connect, Corrosion-Resistan

MTM Hydro Acqualine 40° 4.0 nozzle tip with a rubber guard is a stainless-steel, Italian-made pressure washer tip that delivers a wide 40-degree spray while protecting the orifice and surrounding surfaces.

This Acqualine nozzle tip is built to fit commercial-grade pressure washers and MTM 1/4" quick-coupler systems, combining durable stainless-steel construction with a protective rubber guard for safer, controlled cleaning. It’s optimized for rinsing, light-duty surface cleaning, and detailing tasks where a broad, even spray pattern reduces risk of damage. The threaded stainless-steel tip sits in a stainless nozzle holder and includes a stainless quick-connect plug for fast swapping between foaming and cleaning accessories.

How does the 40° spray angle affect cleaning results?

The 40-degree fan produces a wide, low-impact spray that covers more surface area without concentrating pressure in a narrow stream. That makes it well suited for rinsing soap, washing painted surfaces, and removing loose dirt on vehicles, siding, and delicate finishes.

• Broad coverage to speed up rinsing and light cleaning
• Lower risk of etching or stripping paint compared with narrow tips
• Even water distribution for consistent results

What makes the Acqualine nozzle durable and reliable?

Constructed in Italy from stainless steel, the Acqualine tip and holder resist corrosion and wear from high-pressure water and chemicals. A stainless steel QC plug and threaded assembly ensure a secure, long-lasting fit with MTM quick couplers and other commercial 1/4" systems.

• Stainless-steel tip and holder for corrosion resistance
• Threaded design prevents loosening under pressure
• Stainless quick-connect plug for fast accessory changes

Why is the rubber guard useful for detailing and general cleaning?

The rubber guard surrounds the nozzle outlet, protecting painted surfaces and trim from accidental contact while guiding the spray. It also cushions the tip if it bumps against fragile items and reduces the chance of scratching during close-up work.

• Protects surfaces from hard metal contact
• Helps maintain consistent nozzle-to-surface distance
• Useful when working close to wheels, glass, or painted trim

Is this nozzle compatible with my pressure washer and accessories?

The Acqualine tip is made to work with commercial-grade 1/4" couplers and MTM Hydro’s quick-release fittings, so it swaps easily with foaming lances and other cleaning tools. Check that your pressure washer uses a standard 1/4" quick-connect system or threaded holder to ensure fitment.

• Compatible with MTM 1/4" quick couplers
• Works with most commercial 1/4" coupler systems
• Threaded mount for stable installation

Who is this for: Detailers, professional cleaners, and home users who need a dependable, wide-angle nozzle that minimizes surface risk will benefit from the MTM Hydro Acqualine 40° 4.0 tip. It’s especially useful for car washing, light exterior rinsing, and jobs where a stainless-steel build and quick-change compatibility matter. If you require a higher-impact narrow stream, consider complementary tips; for broad, gentle coverage with surface protection, this Acqualine nozzle is a practical choice.
