This replacement pressure washer trigger gun only works for Karcher electric pressure washer with quick-connect system. If your pressure washer hose has the C-clip then it won’t be compatible. Note: It cannot replace the old model trigger gun G 160 with the black C-clip. Please make sure that your pressure washer hose has a quick-connect fitting instead of C-clip connection. The pressure washer replacement accessory kit is contracted by brass nozzle and plastic housing, lightweight and durable. The high pressure washer spray wand has a rotary nozzle that allows you to adjust from a wide fan spray to a focused steam. It uses a bayonet connection to connect to all Karcher accessories and a quick connection for the high pressure hose. Rated pressure: 2100 PSI/150 Bar. Max water temperature: 60℃/140℉.
