  We consider the three CP-conserving dimension-6 operators that encode the
leading new-physics effects in the triple gauge couplings. The contributions to
the standard-model electromagnetic dipole and semi-leptonic vector and
axial-vector interactions that arise from the insertions of these operators are
calculated. We show that radiative and rare $B$-meson decays provide, under
certain assumptions, constraints on two out of the three anomalous couplings
that are competitive with the restrictions obtained from LEP II, Tevatron and
LHC data. The constraints arising from the $Z \to b \bar b$ electroweak pseudo
observables, $K \to \pi \nu \bar \nu$ and $\epsilon^\prime/\epsilon$ are also
studied.
