Suitable for connection threads G1 (33.3 mm) to G1 (33.3 mm). On one side, the adapter features a standard G1 thread with an axial sealing principle, while on the other side, it has a standard G1 thread with a radial sealing principle. The radial PerfectConnect sealing principle of the BP accessories allows for easy installation, provides particularly reliable sealing, and ensures trouble-free operation of the pumps. This means that both accessories from other manufacturers and older Kärcher accessories can be connected to Kärcher pumps with a radial sealing concept. Additionally, radially sealing accessories from the Kärcher PerfectConnect series can be connected to all conventionally axially sealing pumps.
