Use our teat dip cup for dipping navels, or use it as it was intended at milking time. Our teat dip cup converts from the standard non-return dip cup to a foaming dip cup just by switching tubes. Cup gives full coverage in both modes. The larger bottle has a handy clip for belt or rail. Foaming mode saves up to 50% on teat dip. No wonder everyone's going to this style of teat cup! Foaming mode works best with our new Foam-N-Dip or other foaming dip.
