Product Description

M22 to 3/8" BSP Female High-Pressure Coupling (D-25)

Ensure a flawless, leak-free seal across your high-pressure cleaning equipment with the M22 to 3/8" BSP Female Coupling (D-25). In commercial pressure washing environments, stripped threads or mismatched fittings lead to severe high-pressure water leaks, resulting in a massive loss of cleaning power and dangerous worksite conditions. This precision-engineered brass pressure washer adapter allows operators to seamlessly connect standard M22 hoses or pumps to accessories utilizing a 3/8-inch BSP (British Standard Pipe) thread.

Forged from premium, heavy-duty solid brass, this coupling is highly resistant to chemical corrosion, extreme water temperatures, and the intense physical vibration generated by industrial pumps. The internal geometry is precisely machined to ensure a perfect, watertight seal under maximum operating pressures. Whether upgrading your spray gun, replacing a damaged pump outlet, or building a custom hose extension, this M22 adapter is a vital plumbing consumable for maintaining professional-grade extraction and washing machinery.

Ideal For:

Commercial Pressure Washing: Safely adapts pump outlets, heavy-duty hoses, and spray guns to ensure full pressure delivery without bypass leaks.
Equipment Repair & Customization: Allows mechanics to pair different brands of pressure washer accessories (utilizing BSP threads) with standard M22 systems.
Industrial Plumbing & Fluid Transfer: The robust solid brass construction easily handles high-pressure fluid transfer in demanding factory and agricultural environments.

Key Features & Operational Benefits:

Precision Threading: Converts an M22 standard pressure washer connection to a 3/8" BSP Female thread accurately, eliminating the risk of cross-threading.
Solid Brass Construction: Completely immune to rust and highly resistant to commercial cleaning chemicals, providing a vastly superior lifespan compared to aluminum or plastic fittings.
High-Pressure Tolerance: Engineered with thick walls to safely contain the extreme water pressure generated by industrial cleaning equipment without fracturing.
Hexagonal Grip Profile: The exterior is machined with flat hexagonal sides, allowing technicians to apply maximum torque with a spanner for a permanent, watertight seal.

Technical Specifications:

Product Type: High-Pressure Adapter / Coupling
Fitting 1: M22 (Standard Pressure Washer Thread)
Fitting 2: 3/8" BSP Female (British Standard Pipe)
Material: Solid Brass
Application: Adapting hoses, guns, and pumps on commercial high-pressure equipment.

Frequently Asked Questions

What is an M22 connection?

M22 refers to a metric 22mm thread size. It is one of the most common connection standards used globally for attaching high-pressure hoses to pressure washer pumps and spray guns.

What does 3/8 BSP Female mean?

BSP stands for British Standard Pipe. 3/8-inch is the thread size, and 'Female' indicates it is the threaded socket (the hole) designed to receive a corresponding 3/8-inch 'Male' threaded pipe.

What does the 'D-25' refer to?

D-25 typically refers to the specific manufacturer part profile or European internal dimension standard for the O-ring seating inside the M22 coupling. Ensure this matches your equipment specifications.

Why is brass better than steel or plastic for these fittings?

Solid brass will never rust when constantly exposed to water. It is softer than stainless steel (which helps create a better seal on the threads without stripping them) but far stronger and more heat-resistant than plastic.

Do I need to use thread tape with this fitting?

Yes. When screwing the 3/8 BSP Female side onto a male pipe, you must apply Teflon (PTFE) thread seal tape to the male threads to guarantee a high-pressure, watertight seal.

Will this fix a leaking connection?

If the leak is caused by stripped threads or a cracked fitting, replacing the coupling with this new brass adapter will resolve the leak. If the leak is internal, check the O-rings first.

Can I use this for hot water pressure washing?

Yes, solid brass is highly heat resistant and is perfectly safe for use with commercial hot water pressure washers and boiler systems.

Will this fit my domestic Karcher pressure washer?

Modern domestic Karcher machines typically use a proprietary plastic quick-click hose system rather than standard threaded brass fittings. You must physically verify your machine uses M22 threaded fittings before purchasing.

Do you offer trade pricing for equipment repair technicians?

Yes, Freshway Supplies provides volume pricing and trade accounts for machine repair workshops, plumbers, and commercial cleaners. Contact us to establish your account.
