| Sucker Rod Pump Balls and Seats Harbison-Fischer is a pioneer manufacturer of balls and seats for rod-drawn sub-surface pumps. Special machines are used to lap each seat to a precise size and fit. Each ball and seat combination is vacuum tested on both sides of the seat and individually shrink wrapped and packed in a clear plastic container to seal out contamination and preserve the matched set from being separated. API specifications are met and exceeded for all balls and seats. The following materials are available in
ball and seat sets with the ball and seat being the same material
or a combination of materials. |

| Carbide |

| Standard Stainless |
