Catering Pro Note: The pump knob is often the most abused part of a portable keg setup. If your current knob is cracked or missing, it makes it incredibly difficult to maintain the pressure needed to prevent a “flat” pour. The 431J polymer knob is superior to older wooden or brittle plastic versions because it won’t swell in the rain or snap if the pump is dropped. When installing, simply thread it onto the plunger rod until hand-tight—do not over-torque.
