Switch pressure washer attachments — surface cleaner, wand, gun, or nozzle — without walking back to the machine or shutting down the pump. This carbon steel ball valve installs inline on your 3/8" pressure washer hose and gives you instant on/off control at the point of use, cutting downtime and reducing fatigue on multi-attachment jobs.
