Upgrade your pressure washer setup with this high-quality M22 Male to 3/8" Female Quick Connect Coupling—designed to simplify your workflow and extend the life of your equipment. This brass adapter converts a traditional M22 male thread to a 3/8-inch quick connect coupler, allowing you to easily attach hoses or accessories fitted with a 3/8" male plug. It's ideal for pressure washer owners looking to eliminate thread wear issues, simplify connections, and reduce leaks during use. Engineered for reliability, the coupling supports working pressures up to 4500 PSI (5000 PSI max) and performs in demanding residential or commercial environments. Whether you're changing out hoses, adding a surface cleaner, or connecting a gun to your washer, this adapter ensures a secure and watertight fit. The ball-lock quick-connect design prevents unintentional disconnects and offers a firm grip even under heavy vibration. Crafted from solid brass, the fitting resists corrosion, cracking, and high-pressure fatigue. Over time, pressure washer threads can wear down from repeated use, leading to loosening and leaks. This adapter acts as a clean and stable replacement, helping you maintain consistent pressure and extend the lifespan of your pressure washer, hoses, and accessories. A must-have for anyone seeking a more durable and efficient pressure washing setup.

  • M22 Male to 3/8-Inch Quick Connect Adapter: Converts a standard M22 14mm male threaded connection into a 3/8-inch female quick-connect socket; enables fast attachment of pressure washer hoses, spray guns, and accessories with 3/8-inch male plugs.
  • Rated for 4500 PSI Working Pressure: Supports operating pressures up to 4500 PSI with a maximum pressure capacity of 5000 PSI; suitable for use in heavy-duty pressure washer systems, including residential and commercial cleaning applications.
  • Ball-Lock Mechanism for Secure Connection: Incorporates an internal ball-lock system that holds the connection in place during operation; helps maintain a stable interface and minimize disconnection or fluid seepage under vibration or pressure.
  • Corrosion-Resistant Brass: Manufactured from solid brass to help resist corrosion in wet or high-pressure environments; supports repeated use during frequent attachment changes without damaging threads or internal seals.
  • Replaces Worn Fittings for Better Seal: Used to replace worn or damaged M22 connectors that may cause leaks; helps maintain a consistent connection between the pressure washer and hose by restoring thread alignment and connection integrity.
