This Graco 164250 Pin—also known as the Ball Stop Pin—is an internal component for the T3 Transfer Pump. If your proportioner is supplied by a T3 pump, this is the correct pin.
The Ball Stop Pin acts as a mechanical stop for the pump ball inside the fluid section, helping maintain proper check-valve operation and consistent material feed in the T3 Transfer Pump.
