PWACCS 3/8" Quick-Connect Ball Valve Shut-Off for Pressure Washers, Stainless Steel, 5000 PSI

PWACCS 3/8" Quick Connect Ball Valve is a stainless-steel inline shut-off that lets you instantly stop or resume water flow on compatible pressure-washer hoses and accessories.

If you switch nozzles, surface cleaners, or soap applicators while working with a pressure washer, this compact valve provides a reliable means to pause flow without walking back to the machine. Built from stainless steel and rated for high pressures, it installs between 3/8" quick-connect components to isolate the spray at the hose, gun, or accessory end. The simple 90° black handle gives clear on/off control, and the DN10 ball design minimizes pressure loss when open.

How does this valve make nozzle and accessory changes easier?

The valve stops water at the connection point so you can change tools without spraying or needing to depressurize the whole system. That saves time and reduces trip hazards from stray spray.

• Place between the gun and hose or between hose and accessory to cut flow locally.
• Turn the handle 90° to close the stream before detaching a connector.
• Resume spray instantly by returning the handle to the ON position.

What pressure and temperature limits should I expect?

This valve is engineered for pressure-washer use up to 5000 PSI and temperatures up to 158°F (70°C). Those ratings make it suitable for most gas- and electric-driven washers intended for outdoor cleaning tasks.

• Maximum working pressure: 5000 PSI for high-pressure cleaning tasks.
• Maximum fluid temperature: 158°F / 70°C — suitable for warm water but not steam.
• Not rated for corrosive chemicals, gases, or household plumbing service.

Which fittings and systems are compatible with this shut-off valve?

The valve is made for 3/8" quick-connect pressure-washer fittings; confirm plug and socket orientation before installation. It functions as an inline DN10 ball valve, so matching quick-connect ends are required for a secure connection.

• Works with pressure washers and accessories that use 3/8" quick-connect couplers.
• Check whether your hose, gun, pump, or accessory is a plug or socket style to ensure correct placement.
• Use thread sealing tape and proper tightening on any threaded adapters to prevent leaks.

How durable and safe is the construction for outdoor cleaning?

PWACCS built this valve with a stainless-steel body to resist corrosion and handle repeated pressure cycles. The compact ball-valve design reduces internal turbulence and keeps flow smooth when open; still, it should only be used within the stated limits and for water-based cleaning tasks.

• Stainless-steel DN10 body for improved resistance to rust and wear.
• Simple black 90° handle for quick, unambiguous on/off control.
• Intended for pressure-washer water lines only — not for steam, gas, or corrosive fluids.

Who is this for: The PWACCS 3/8" Quick Connect Ball Valve is designed for homeowners, detailers, and professional cleaners who regularly swap pressure-washer nozzles, surface cleaners, or soap applicators and want a faster, safer way to stop flow at the hose or accessory. If you use a pressure washer with compatible 3/8" quick-connect ends and need reliable inline shut-off control rated for high-pressure outdoor cleaning, this valve is a practical addition to your kit.
