Tube Fittings

Finding the Right Fittings

When you’re dealing with high-pressure environments, you can’t afford a leak. Here are five factors to consider when you’re searching for the right fitting: S.T.A.M.P.

  • Size: Tube size, particularly wall thickness, is one factor that will determine which fitting you should choose. Flare-type fittings usually have a maximum wall limitation, while flareless fittings have a minimum wall limitation. Flow, service environment, temperature and system pressure also affect size.
  • Temperature: The type of fitting material and seal dictates what system and environment temperature the particular fitting can withstand.
  • Application: Elements of the application’s system environment — such as mechanical load and vibration — influence the fitting material you will need and whether you need a coating or protective plating.
  • Media: The type of fluid moving through the fitting will also affect which type of fitting should be selected.
  • Pressure: The fitting pressure should be equal to or greater than the system pressure.
