Adapter Karcher 2 M22IG-TR22AG for pressure washers, model 4.111-030.0

Karcher Adapter 2 M22IG-TR22AG (model 4.111-030.0) is a threaded connector engineered to convert an M22 internal (female) connection to a TR22 external (male) connection for pressure washer accessories. The adapter provides a compact means to link hoses, lances and cleaning tools that use different thread standards, allowing users to expand compatibility without replacing existing components. Designed for routine workshop and domestic cleaning tasks, the adapter supports quick coupling and stable mechanical connection under typical pressure washer operating conditions.

Advantages

The adapter combines a precision-machined thread interface with corrosion-resistant materials to ensure reliable engagement and a leak-minimised joint. Its compact design preserves flow characteristics and reduces potential kink points in the connection. Installation and removal require no special tools, which simplifies swapping nozzles or extensions during cleaning operations. The adapter’s standardized threads make it suitable for integration with a wide range of common pressure-washing accessories.

Suitable for

• Connecting M22-threaded hoses or lances to TR22-threaded accessories
• Extending compatibility between different pressure-washer fittings during maintenance
• Workshop and garage cleaning tasks with portable or stationary pressure washers
• Home exterior cleaning where quick tool changes are required

Key specifications

• Thread conversion: M22 internal (female) to TR22 external (male)
• Construction: metal alloy with corrosion-resistant finish
• Connection type: threaded, reusable
• Suitable for standard pressure washer accessory dimensions and pressures
• Compact form factor for minimal added length and flow restriction

How to use

Ensure both mating surfaces are clean and free of debris before assembly. Hand-thread the adapter into the M22 female fitting until it seats, then tighten by hand to obtain a secure connection; do not overtighten. Attach the TR22 male accessory and verify engagement by hand-turning until snug. After assembly, run the pressure washer briefly at low pressure to check for leaks and correct seating; if leakage is observed, stop and re-seat the connections. Follow the pressure washer manufacturer’s safety instructions when operating the system.

Usage recommendations

Use the adapter with compatible M22 and TR22 threaded accessories only. Regularly inspect threads and sealing surfaces for wear or damage and replace the adapter if deformation or corrosion compromises the seal. Avoid using thread sealants that are not specified for high-pressure water use; if needed, use a compatible sealant sparingly. Store the adapter dry and protected from impact to maintain thread integrity.
