What Is a Hose Pipe Nipple?
A hose pipe nipple is a specialized fitting featuring a male threaded connection on one end and a barbed hose connector on the other. The barbed end may match the pipe thread size or be reduced for smaller hoses. These fittings are commonly made from 304 or 316 stainless steel, offering superior strength and corrosion resistance for demanding applications.
Key features include:
NPT (National Pipe Taper) threads for leakproof sealing
Hose barb design for secure hose attachment
ANSI B1.20.1 compliant for quality assurance
Highpressure resistance (up to 20,000 psi in some applications)

How to Install a Hose Nipple
- Threaded Connection
Screw the NPTthreaded end into the corresponding female port using pipe tape or sealant for a secure fit.
- Hose Attachment
Slide the barbed end into a compatible rubber or thermoplastic hose.
Secure with a hose clamp or crimp ferrule for pressure retention.
- Pressure Testing
Always test the connection at 50% above working pressure before full operation.
Applications of Hose Nipples
Hose nipples are essential in industries requiring reliable fluid transfer:
Chemical Processing – Acids, solvents, fertilizers
Marine & Offshore – Saltwater cooling, bilge systems
Agriculture – Herbicide/pesticide distribution
Oil & Gas – Fuel transfer, hydraulic systems
Manufacturing – Coolant lines, compressed air
