Hose Nipple
What is a Hose Nipple?
A Hose Nipple is a threaded fitting machined from solid bar stock, used to connect flexible hoses to rigid piping systems. One end features male pipe threads, while the other is a barbed or smooth shank to securely grip the hose using clamps or ferrules.
Hose nipples are ideal for air, gas, steam, oil, and fluid transfer lines across various industries like agriculture, marine, industrial plants, and chemical facilities.
