APOWER Pressure Washer Quick Connect Kit M22-14mm to 3/8in Adapters — 9‑pc 304 Stainless with Viton O‑rings

The APOWER Pressure Washer Quick Connect Kit is a 9-piece stainless-steel adapter set that converts M22-14mm and 3/8" fittings plus garden-hose connections into fast, leak-resistant quick-release hookups for gas and electric washers.

Whether you want to join two pressure washer hoses, adapt garden hose threads to your pump inlet, or swap between gun and lance in seconds, this kit supplies the common adapters, plugs, sockets and a coupler to simplify connections. All connectors are made from 304 stainless steel and use upgraded black Viton O-rings for stronger chemical and temperature resistance than standard rubber seals. Maximum working pressure is rated up to 5000 PSI, making the set appropriate for most home and light-professional cleaning applications — but first confirm your hose uses an M22-14mm fitting (14mm plug diameter), not 15mm, to avoid leaks.

How will this kit speed up my pressure-washing tasks?

Quick-connect fittings let you attach or detach hoses, guns and lances in seconds without threaded assembly or tools, saving time between jobs or when switching accessories. The included coupler lets you join two hoses to extend reach without compromises.

• Two M22-14mm male/female quick-connect pairs for pump-to-hose and hose-to-gun links
• 3/8" plug and socket adapters for common pressure-line fittings
• Adapters converting 3/4" garden-hose threads to 1/2" quick-connect plugs/sockets
• One M22-14mm male-to-male coupler to join hoses and lengthen reach

Are these connectors durable and leak-resistant?

Yes — each component is machined from 304 medical-grade stainless steel for corrosion resistance and long service life. Black Viton O-rings provide improved resistance to heat, oils and cleaning chemicals compared with standard rubber seals, reducing the chance of leaks under typical use.

• 304 stainless steel bodies resist rust and tarnish
• Upgraded Viton O-rings for chemical and temperature durability
• Precision-fit plugs and sockets for secure, smooth operation
• Rated for up to 5000 PSI working pressure for robust performance

Which hoses and washers are compatible with this set?

The kit is designed primarily for gas-powered pressure washers and electric washers that use standard M22-14mm hoses and common 3/8" pressure connections. Before buying, check your hose plug diameter is 14mm (not 15mm); using the wrong size will cause leaks.

• Compatible with standard M22-14mm pressure washer hoses
• Adapters for 3/8" pressure-line fittings and 3/4" garden-hose threads
• Useful for pumps, guns, lances, and garden-hose-to-pump conversions
• Not compatible with hoses requiring 15mm fittings (will leak)

What comes in the box and what support is available?

The kit contains nine main pieces plus spare O-rings and Teflon tape so you can install adapters immediately. APOWER offers 24-hour customer service and a user manual is included to guide correct installation and sizing verification.

• 2 x M22-14 female + 3/8" plug, 2 x M22-14 male + 3/8" socket
• 2 x 1/2" plug + 3/4" male, 2 x 1/2" socket + 3/4" female
• 1 x M22-14mm male-to-male coupler, 4 spare O-rings, 2 x Teflon tape, user manual
• 24-hour customer support from APOWER for product questions or issues

Who is this for: The APOWER Quick Connect Kit is ideal for homeowners who regularly pressure-wash cars, driveways or siding and need faster accessory changes; DIYers who want to convert garden-hose threads to pump inlets; and mobile detailers who require durable, corrosion-resistant fittings. If you use pressure washers with M22-14mm hoses and want to reduce setup time, extend hose reach, or swap tools quickly, this kit provides a compact, ready-to-use collection of adapters. If your hose measures 15mm at the plug, choose a compatible kit to prevent leaks.
