Shop 4501 90-Degree Hose Barb - Male NPTF

The Series 4501 90-Degree Hose Barb x Male NPTF adapters, made from high-quality carbon steel, are designed to connect hoses to male NPTF (National Pipe Tapered Female) threaded components in fluid power systems. These adapters feature a 90-degree hose barb on one end, which securely grips the inside of a hose when it is slid over the barb and tightened with a hose clamp. This creates a strong, leak-resistant connection. The other end of the adapter is equipped with male NPTF threads, which form a tight, leak-proof seal through the deformation of the threads, ensuring a reliable connection. Hose barb adapters like the Series 4501 are commonly used to connect flexible hoses to rigid piping, offering ease of installation and secure fluid transfer for a wide range of industrial and hydraulic applications. The carbon steel construction ensures durability and longevity in high-pressure environments.
