In this work we study possible connections between B-meson anomalies and Kaon physics observables in the context of combined solutions with the singlet and triplet scalar leptoquarks and
. By assuming a flavor structure for the leptoquark couplings dictated by a minimally broken
flavor symmetry we can make a sharp connection between these two classes of observables. We find that the bound on
from NA62 puts already some tension in the model, while the present limits on
and
conversion in nuclei can be saturated. Relaxing instead the flavor assumption we study what values for
, as well as for
and
, are viable compatibly with all other phenomenological constraints.
