Gyfent Pressure Washer Gauge Kit 0–6000 PSI M22-14 (3/8" QD) — Stainless-Steel Gauge & Brass Adapters

If you run a gas or electric pressure washer with an M22-14 outlet, this kit gives you a clear, reliable way to monitor system pressure and add flexible quick-connect hookups. The kit combines a dual-scale stainless-steel gauge, multiple brass adapters, quick-disconnect fittings and sealing tape so you can install it right at the pump or in-line on the hose. It’s built to resist corrosion and withstand demanding outdoor use while converting between common thread sizes.

How do I read pressure and what units are shown?

The gauge uses a dual-dial face that simultaneously displays PSI and MPa so you can read whichever unit your workflow requires. The pointer is designed for minimal vibration, which helps ensure legible, steady readings even under fluctuating flow. Accuracy is specified to ±2.5% with a maximum readout of 6000 PSI.

• Dual-scale face shows PSI and MPa at once
• Maximum range: 0–6000 PSI
• Accuracy: ±2.5% (Error ±145 PSI)
• Vibration-resistant pointer for clearer readings

Which machines and outlets will this kit fit?

This kit is intended for pressure washers with an M22 water outlet whose M22-14 swivel inner diameter measures 14mm. It includes adapters to connect standard hose threads and quick-disconnect fittings commonly used on pumps and spray guns. Verify the outlet size on your unit before purchase to avoid leaks or mismatches.

• Compatible with gas and electric washers using M22-14 outlets
• Includes 3/8" quick connect and multiple thread adapters
• Converts 3/4" garden hose threads to pressure-washer inlet sizes
• Check that the M22 swivel inner diameter is 14mm (not 15mm)

What materials and durability features does the kit offer?

The gauge housing is stainless steel for corrosion resistance and long service life, while the adapter set is brass to resist wear and create reliable threaded connections. The components are designed to tolerate outdoor conditions and repeated assembly without deforming or cracking. Included sealing tape helps ensure leak-free joints during installation.

• Stainless-steel pressure gauge body for corrosion resistance
• Brass adapters and swivel fittings for robust threads
• Supplied sealing tape to prevent leaks at connections
• Built to withstand regular, heavy-duty outdoor use

How easy is installation and what connections are provided?

Installation is straightforward: the gauge fits in-line between the pump outlet and hose, using the supplied 3/8" quick-connect and adapter pieces to match common fittings. The kit contains both male and female adapters, plugs and swivel joints, letting you assemble the exact configuration you need without additional purchases.

• Includes 3/8" QD + M22-14 male and M22-14 swivel + 3/8" plug
• Contains 1/2" plug + 3/4" male and 3/4" female + 1/2" quick connect
• Connects directly between pump outlet and pressure hose or gun
• Sealing tape provided to finish threaded joints

Who is this for: The Gyfent Pressure Washer Gauge Kit is aimed at DIYers, professional cleaners and equipment owners who need an accurate, durable in-line pressure readout and versatile connection options. If you operate a pressure washer with an M22-14 outlet and want to monitor system pressure, prevent overpressure events, or simplify hose-to-pump hookups, this kit supplies the gauge, adapters and sealing hardware in one compact package. Confirm your pump’s M22-14 size before ordering to ensure a leak-free fit.
