Stainless Steel Hex Nipple – 1/4 in. MNPT (IHN-4N)

This 1/4″ Male NPT hex nipple is engineered for reliability in the most demanding process conditions. Made from 316 stainless steel, it combines corrosion resistance with the strength needed for high-pressure systems. Precision machining delivers uniform thread engagement that meets ANSI B1.20.1 standards, ensuring consistent sealing and dependable performance across a wide range of fluid and gas applications.

With a pressure rating of 8000 PSIG, this component is designed for environments where leaks are unacceptable and uptime is critical. The hex-body design allows installers to apply secure torque using standard wrenches, reducing the risk of galling and making field service faster and more efficient. Its compact profile allows technicians to fit connections into tight spaces without sacrificing strength or long-term reliability.

This fitting is widely used in chemical injection skids, sanitary process loops, instrumentation panels, and fuel distribution systems. By enabling straightforward line extensions and branch connections, it plays a key role in both new builds and retrofit projects. Its ability to withstand vibration, temperature cycling, and harsh chemicals makes it a trusted choice for OEMs and system integrators who demand proven performance in critical applications.
