Foam Cannon Pressure Adjustment Knob Replacement, 2-Pack Solid Brass Threaded Detailing Part

Each knob is turned from solid brass with a tapered, threaded base and a slotted head, so it seats cleanly into the metering channel and lets you dial the spray from a wide rinse to a thick, clinging lather. The brass body resists corrosion from soaps and hard water far better than plastic knobs that strip out after a season of weekend washes.

Sold as a matched 2-pack so you always have a spare in the drawer. Thread the worn knob out, thread the new one in, and you are back to controlling foam thickness without buying a whole new cannon.
