The 3/8″ Hose Stem 3/8″ Barbed Adapter is a fluid fitting designed to connect a flexible 3/8″ hose to another fluid line or device. The hose stem end allows insertion into a tubing or hose connection, while the barbed adapter provides a secure, leak-resistant grip for the hose. This adapter is ideal for low- to medium-pressure applications in pneumatic, or liquid transfer systems.
