Hose barb fittings, also known as hose barbs or beaded hose stem fittings, are a type of hose fitting used to connect flexible tubing or hoses to various components in fluid transfer systems. They have a barbed end that is inserted into the inner diameter of a hose or tube, creating a secure, leak-tight connection.

They are intended for use in suction or low pressure lines, typically less than 300 psi, and used in a variety of applications, including plumbing, automotive, and industrial settings.
