نظرة عامة على المنتج

Advanced 7NU Series Straight NPT Female to NPSM Female Swivel 60° Cone Hydraulic Adapter

The 7NU Series is a heavy-duty straight fluid connection component specifically engineered for inline transitions between external ANSI/ASME B1.20.1 tapered NPT male pipe threads and American National Standard Straight Mechanical Pipe (NPSM) male fittings or hose assemblies. Featuring a tapered NPT female threaded body paired with a free-spinning NPSM female swivel nut with an internal 60° cone seat, this dual-female adapter enables rapid, twist-free plumbing onto fixed male connections, delivering high structural rigidity and zero-leak reliability under severe dynamic pressures.

Core Hydraulic Advantages

  • Twist-Free NPSM Swivel Architecture: The free-spinning female swivel nut rotates independently around the straight adapter body, allowing effortless tightening onto fixed male lines without transmitting destructive torsional stress or twisting connected hose assemblies.
  • 60° Cone Metal-to-Metal Sealing: Precision-machined 60-degree internal cone seat clamps firmly against the mating male chamfer, forming an airtight, vibration-resistant mechanical dry seal without relying on elastomeric O-rings.
  • Tapered NPT Thread Sealing Dynamics: Precision CNC-machined internal 60-degree tapered pipe threads engage flank-to-flank with mating male NPT fittings, providing a dependable mechanical seal (or enhanced seal with anaerobic sealant) resistant to high pressure spikes.
  • Dual-Hex External Geometry: Integrated heavy-duty hex flats on both the main body and the swivel nut provide positive wrench engagement for controlled, counter-held torque application during assembly and disassembly.
  • 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 extreme line pressures.

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