Advanced 1JN Series Straight JIC Male 37° Flare to NPT Male Hydraulic Adapter

The 1JN Series is a versatile fluid connection component specifically engineered for straight in-line transitions between American SAE J514 / ISO 8434-2 female JIC swivel hose assemblies and ANSI/ASME B1.20.1 tapered NPT female manifold ports. Featuring a precision-machined JIC male 37° flare cone end on one side paired with a tapered NPT male thread stud on the other, this straight adapter guarantees smooth laminar fluid flow, positive thread-wedging sealing, and exceptional mechanical stability under severe dynamic pressure impulses.

Core Hydraulic Advantages

Tapered NPT Thread Sealing Dynamics: Precision-cut 60-degree tapered pipe threads wedge tightly into mating internal NPT ports, establishing a dependable metal-to-metal seal (or enhanced seal with anaerobic thread sealant) resistant to high pressure and fluid migration.
SAE J514 / ISO 8434-2 37° Flare Performance: Precision-machined 37-degree cone seat mates seamlessly with standard female JIC swivel hose ends, providing an airtight, metal-to-metal dry seal without relying on elastomeric O-rings.
Solid Hexagonal Body Profile: Precision CNC-machined central hex section provides substantial wrench engagement area, ensuring smooth counter-holding and accurate torque tightening during port installation and routine maintenance.
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 JIC to NPT adapter ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
