Product Overview

Advanced 9J Series JIC Female Swivel 37° Flare Hydraulic Sealing Cap

The 9J Series is a premium line-terminating component specifically engineered for dead-ending and protecting male threaded lines and adapters within SAE J514 / ISO 8434-2 standard hydraulic architectures. Utilizing a two-piece assembled configuration consisting of a free-spinning JIC female swivel nut and an internal precision-formed 37° flare sealing plug, this cap allows effortless installation onto fixed male fittings without binding, delivering positive metal-to-metal dry shutoff, complete contaminant exclusion, and zero-leak reliability under severe dynamic pressure impulses.

Core Hydraulic Advantages

  • Twist-Free Swivel Nut Mechanism: The free-spinning female nut independently rotates around the internal sealing seat, enabling rapid, smooth thread engagement and precise torque tightening onto fixed male lines without transmitting rotational drag or scoring the sealing cone.
  • SAE J514 / ISO 8434-2 37° Flare Sealing Dynamics: Internal precision-machined 37-degree cone seat clamps firmly against the mating male nose cone, forming an airtight, vibration-proof metal-to-metal dry seal without relying on elastomeric O-rings.
  • Total Fluid Isolation & Port Protection: Provides a robust positive seal for unused test ports, auxiliary power take-off lines, and manifold passages, completely preventing pressure drop, fluid weepage, and ambient particulate ingress.
  • 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 female swivel flare cap ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
