Foam Cannon Connector for Karcher K Series pressure washers, fitting Karcher K1 - K7.
There's a new karcher K1 that doesn't fit, other karcher k series all fit this connector.
The Brass Connector and Nylong PA connector are same size and same compatability.
Nylon PA version is with the connection tube built in, no need extra male to male connection bar. Nylon PA is robust enough. Best Value.
Karcher K Brass connector is with just brass female thread built in, brass material feels better, and price is good value.
