Precision Under Pressure — The Professional's Choice for High-Performance Cleaning

The Mastech MT WG22 Water Gun is a high-pressure nozzle accessory engineered for professional-grade pressure washers and jet cleaners. Designed to deliver a focused, high-velocity water stream, this precision attachment handles everything from heavy-duty industrial cleaning to detailed surface preparation, operating at pressures up to 4350 psi (300 bar) and temperatures up to 60°C (140°F). Built for durability and consistent performance, it is a trusted spare part replacement for demanding commercial and residential environments.

Key Features Perfect For
  • Ultra-high pressure rating up to 4350 psi / 300 bar
  • Wide operating temperature tolerance up to 60°C / 140°F
  • Precision-engineered focused water stream for targeted cleaning
  • Compatible with standard Mastech pressure washer systems
  • Durable construction for long-term, heavy-duty use
  • Industrial and commercial pressure washing operations
  • Surface preparation before painting or coating
  • Concrete, brick, and metal deep cleaning
  • Replacing worn or damaged OEM water gun nozzles
  • Maximum Operating Pressure of 4350 psi (300 bar): The MT WG22 is rated for an exceptional pressure range starting from 2174 psi (150 bar) up to a peak of 4350 psi (300 bar), making it suitable for the most demanding stripping, degreasing, and surface cleaning tasks where standard nozzles fall short.
  • High-Temperature Resistance up to 60°C (140°F): Engineered to withstand hot water pressure washing applications, the nozzle maintains structural integrity and sealing performance at elevated temperatures, critical for cutting through grease, oil, and industrial residue that cold water alone cannot remove.
  • Focused High-Velocity Water Stream: The precision-machined nozzle geometry channels water into a concentrated, high-impact jet, maximizing kinetic energy at the point of contact. This translates to faster cleaning cycles, reduced water consumption, and superior material removal efficiency compared to wide-angle or low-pressure alternatives.
  • OEM-Compatible Spare Part for Mastech Pressure Washers: Manufactured as a genuine Mastech replacement component (Part No. 26494), the MT WG22 is designed for direct compatibility with Mastech pressure washer systems. It restores full operational performance without the need for adapters or modifications, ensuring a secure, leak-free connection.
  • Heavy-Duty Build for Extended Service Life: Constructed from materials selected for corrosion resistance and mechanical durability, the water gun is built to endure repeated high-pressure cycles in harsh environments, including exposure to detergents, mineral-laden water, and outdoor conditions, without degradation in performance or fit.
  • Includes Operator Guide Book: Each unit ships with a dedicated guide book covering installation, safe operating procedures, and maintenance recommendations to ensure correct setup and maximize the service life of the nozzle within your pressure washing system.

General Purchase & Comparison Queries

Is the Mastech MT WG22 a genuine OEM spare part?

Yes. The Mastech MT WG22 Water Gun (Part No. 26494) is a genuine Mastech spare part, manufactured to the same specifications as the original component supplied with Mastech pressure washer units. It is not an aftermarket or third-party substitute, which means you can expect a precise fit, consistent pressure performance, and full compatibility without requiring adapters or modifications.

How does the MT WG22 compare to universal aftermarket water gun nozzles?

Universal aftermarket nozzles are designed to fit a broad range of machines and often involve compromises in fit tolerance, pressure rating, and material quality. The MT WG22 is engineered specifically for Mastech systems, ensuring a leak-free seal, full pressure delivery up to 4350 psi (300 bar), and temperature resistance up to 60°C (140°F) — performance benchmarks that generic alternatives frequently cannot match under sustained heavy-duty use.

What is included with the Mastech MT WG22 Water Gun?

The package includes the MT WG22 Water Gun nozzle and a Guide Book (1 piece) covering installation instructions, safe operating parameters, and maintenance guidelines. The guide book is an important reference for ensuring the nozzle is installed correctly and operated within its rated pressure and temperature limits.

Product-Specific and Usage Queries

What is the maximum pressure and temperature this water gun can handle?

The Mastech MT WG22 is rated for a maximum operating pressure of 4350 psi (300 bar), with a minimum operating pressure of 2174 psi (150 bar). It supports a maximum water temperature of 60°C (140°F), making it compatible with both cold and hot water pressure washing systems. Always ensure your pressure washer's output does not exceed these rated limits to maintain safe and reliable operation.

Can the MT WG22 be used for hot water pressure washing?

Yes. The MT WG22 is designed to operate with water temperatures up to 60°C (140°F), making it suitable for hot water pressure washing applications. Hot water washing is particularly effective for removing grease, oil, wax, and biological contaminants that resist cold water treatment. Ensure your pressure washer's hot water output temperature does not exceed the 60°C threshold to avoid seal degradation or component damage.

What surfaces and applications is the MT WG22 best suited for?

The MT WG22's high-pressure, focused water stream makes it well-suited for a wide range of demanding applications, including concrete and brick cleaning, metal surface degreasing, vehicle and equipment washing, surface preparation prior to painting or coating, and industrial facility maintenance. Its pressure range of 2174–4350 psi covers both medium-duty commercial tasks and heavy-duty industrial cleaning requirements.

Problem/Solution-Oriented Queries

My Mastech pressure washer is losing pressure — can replacing the water gun nozzle fix this?

Yes, a worn or damaged water gun nozzle is one of the most common causes of pressure loss in pressure washer systems. Over time, the nozzle orifice can erode, causing the water stream to lose focus and the system to lose back-pressure. Replacing the nozzle with a genuine Mastech MT WG22 (Part No. 26494) restores the correct orifice geometry, re-establishes the rated pressure output, and eliminates leaks at the gun connection point.

The water gun on my Mastech pressure washer is leaking at the connection — what should I do?

Leaks at the gun-to-lance or gun-to-hose connection are typically caused by worn seals, a cracked gun body, or a damaged thread interface. Since the MT WG22 is a genuine OEM replacement, it includes correctly dimensioned threads and sealing surfaces that match Mastech system tolerances precisely. Installing the MT WG22 eliminates fit-related leak points. If the leak persists after replacement, inspect the high-pressure hose and lance connections for damage as the source may be upstream of the gun.

Can I use the MT WG22 with a non-Mastech pressure washer?

The MT WG22 is designed and validated for use with Mastech pressure washer systems. While it may physically connect to other brands that use compatible thread standards, Mastech does not certify its performance or safety on third-party machines. Using it on a non-Mastech unit could result in connection leaks, pressure mismatches, or voided warranties. For non-Mastech machines, we recommend sourcing a nozzle specified by your equipment's manufacturer.
