Advanced 2NU Series Straight NPT Male to NPSM Female Swivel 60° Cone Hydraulic Adapter

The 2NU Series is a heavy-duty straight fluid connection component specifically engineered for transitions between ANSI/ASME B1.20.1 tapered NPT female manifold ports and American National Standard Straight Mechanical Pipe (NPSM) male fittings or hose assemblies. Featuring a tapered NPT male thread stud on one end paired with a free-spinning NPSM female swivel nut with an internal 60° cone seat on the other, this straight adapter enables fast, twist-free line connection and positive mechanical sealing under severe dynamic hydraulic pressures.

Core Hydraulic Advantages

Twist-Free NPSM Swivel Action: The free-spinning female swivel nut rotates independently around the straight-thread adapter body, allowing effortless alignment and tightening onto fixed male lines without imparting torsional strain or twisting connected hoses.
60° Cone Metal-to-Metal Sealing: Precision-machined 60-degree internal cone seat mates firmly against mating male chamfers, establishing an airtight, vibration-resistant mechanical seal that does not depend on elastomeric O-rings.
Tapered NPT Thread Sealing Dynamics: Precision CNC-machined 60-degree tapered pipe threads wedge flank-to-flank into internal NPT ports, delivering a dependable mechanical seal (or enhanced seal with anaerobic sealant) resistant to fluid migration and high pressure surges.
Straight-Through Laminar Flow: Streamlined internal bore design ensures unobstructed fluid conveyance with minimal turbulence, mitigating cavitation and system pressure drops across the connection.
Exceptional Blowout Resistance: Precision CNC-machined from your choice of premium high-strength carbon steel or corrosion-resistant 304/316 stainless steel, delivering maximum pull-out resistance, dimensional stability, and burst-proof performance under severe pressure spikes.

With optional zinc-nickel alloy surface treatment available to significantly extend service life, this hydraulic straight NPT male to NPSM female swivel adapter ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
