Questions & Answers 3

Questions and answers of the customers

  1. Q I am under the impression that 304 stainless fittings are not 3-A rated.. After research, I'm finding that 316 stainless fittings are the only 3-A rated fittings.
    A Hello and thanks for your question. 3-A rating is completely independent of the type of alloy used whether that be 304 or 316L stainless steel. Instead, 3-A certification is based upon the design and more importantly, the "cleanability" of the fitting itself rather than the chemical composition. On a related note, 3-A certification does require a certain level of Surface Finish, or Roughness Average (Ra) to be compliant. The reason for this is that at a microscopic level, fittings with a rougher finish are more susceptible to harboring bacteria and thus more difficult to clean. You can learn more about 3-A certification and surface finish by watching this video. For more questions on 3-A certification and the necessary requirements please visit the 3-A Organization website.
  2. Q I need 2) 8' sections of 6433 cu uhmwp tubing. can you send me an invoice and I will pay you for them. Thanks John
    There are no answers for this question yet.
  3. Q If these hoses get steamed out regularly, then is there a recommended shelf-life for such hoses? To be clear, they do not get steamed continuously, but they do get steamed regularly.
    A The 6433 and the 6506 can both be cleaned with steam. The important thing with steam is to keep the cleaning cycle to 15 minutes or less and to keep the temperature around 212°F. Also, make sure the hose is hung up and drained afterward. Attached is the manufacturer (NovaFlex) best practices for cleaning. In the food and beverage area, a lot of people are cleaning with steam. We typically see hose assemblies lasting about 4 years in breweries. It can be shorter or longer depending on use. When it is time to replace you will notice the walls of the innertube will start to show wear. Sometimes you can see this by shining a flashlight down the hose end. Some people are even buying cheap endoscopes online and periodically inspecting the inside of their hose assemblies.
