What is TR22 K-Lock?

TR22 K-Lock is the professional hose connection system used on many Kärcher Professional pressure washers. It features mostly gray locking connections found on many pro-series devices. Unlike home & garden quick-connect systems, K-Lock offers a reliable, twist-proof connection built for daily professional use. This system is common on commercial Kärcher machines, hot water units, and powerful cold water pressure washers.

Upgrade to 3/8" Pro Components

This adapter converts the Kärcher TR22 K-Lock system to the widespread 3/8 inch standard. It lets you integrate professional accessories like MTM Hydro SGS35, SGS28 spray guns, lances, foam cannons, or quick connect systems easily. This gives significantly more flexibility for configuring pro-level pressure washer setups.

Solid Brass Construction

The adapter is made from high-quality solid brass, designed for long-lasting use under high pressure and temperature loads. Brass ensures excellent corrosion resistance, outstanding pressure strength, and extended durability – perfect for demanding applications in car care, industry, and commercial use.

Ensure secure attachment of components before each use. For sealing, we recommend Loxeal 53-14 thread sealant or PTFE Teflon tape. If you have any questions about fitting, we are happy to assist.
