Frequently Asked Questions
The pin secures the ball inside the check valve, allowing it to seat correctly and prevent fluid backflow. Without the correct pin, the valve may leak or fail to hold pressure.
Compatibility depends on the check-valve assembly. If your sprayer uses check valve 206831, 206833, or 206962, then this pin will fit. Always verify with your sprayer’s parts list.
Replace the pin during a check-valve rebuild or whenever you notice wear, ball misalignment, or valve leakage. It is a small but critical component for maintaining pressure stability.
