    Sanitary Fittings, LLC provided outstanding products and services. The online ordering process was clear, easy and secure. Everything I needed was in stock and easily found on the website. I ordered using my credit card and received immediate email confirmation of my order. Order status emails kept me informed with receipt and tracking info. The parts arrived sooner than expected and exceeded my expectations. I will order from Sanitary Fittings again.

    One suggestion for packaging: The small gaskets were in a little plastic bag, which was loose in a large box. Could get lost easily if you didn’t know what to look for. Putting them into a white envelope taped to the inside of the box might be better.
