Questions and answers of the customers

  1. A I'm sorry, but most of the products available on Sanitary Fittings are not ASME certified. ASME is usually required within the bio-pharmaceutical industry and is not typical for most installations. Our heavy duty tank weld ferrule is the only product that we sell to meet that certification at the moment. Please check back often and our product line continues to expand.
  2. A Hello, great question! This comes up very often with tri-clamp / tri-clover fittings. The OD diameter of the flange varies with the sanitary fitting size. In all cases the outside diameter of the flange will be GREATER than the sanitary fitting diameter. This is a common mistake for people new to purchasing sanitary fittings. For exact measure sizes of flange, tube and fitting please consult our handy Clamp Fittings and Gasket Sizing Guide available on all clamp connection product pages. Thanks for asking.
