Tough Balls That Seal and Last
Silicon nitride balls are tough and resist cracking and breaking, so they hold up in rod pump service where other balls chip or wear out of round.
We recommend Grade 25 over Grade 40. Grade 25 balls are more precise and spherical, which means better roundness and a better seal on the seat.
