37° Flare (JIC) Female Connector: Male JIC to Female Pipe Adapter
Bridge the gap between your JIC flared systems and NPT/BSPP pipe ports. The Stark 37° Flare Male to Female Pipe Adapter is a high-integrity converter, engineered to connect with a female JIC (37° Flare) hose or tube fitting to a female NPT or BSPP threaded port. Its one-piece forged 316/316L stainless steel design provides a robust, leak-free transition, making it the essential component for integrating hydraulic hoses, connecting to equipment ports, and bridging different piping standards.

🛠 The Engineering Advantage
- Reliable System Integration: This adapter provides a seamless, single-piece solution for connecting flexible JIC hose assemblies to the fixed, female-threaded ports on pumps, cylinders, and manifolds, eliminating the need for multiple intermediate fittings.
- Proven Metal-to-Metal Seal (JIC Side): The 37° flared cone provides a highly reliable metal seal against the female JIC fitting, ensuring leak-free performance even in high-vibration hydraulic systems.
- Global Standard Compliance (SAE J514): Our fittings are manufactured to the strict dimensional tolerances of SAE J514 / ISO 8434-2. This guarantees full interchangeability with other compliant JIC fittings from major brands like Parker® and Swagelok®.
- Forged Body for High-Pressure Integrity: Machined from one-piece forged 316/316L stainless steel, our adapters offer superior strength and fatigue resistance to handle the high pressures and pressure spikes inherent in hydraulic systems.

📌 Targeted Application Support
- Hydraulic Hose Connection: The primary application for connecting a standard JIC female hose end to a female NPT or BSPP port on a piece of equipment.
- System Transition Point: Allows a system built with JIC tubing to easily connect to components that only have pipe thread ports.
- Test Benches: Provides a flexible way to connect various instruments and devices with different thread types.
- OEM Equipment Manufacturing: Used by equipment manufacturers to provide a standardized JIC connection point on their products.
❓ Frequently Asked Questions (FAQ)
Q1: What is the main purpose of this adapter?
Its main purpose is to convert a female pipe thread port (like NPT or BSPP) into a male 37° Flare (JIC) connection. This is most commonly used to connect a flexible hose with a female JIC end to a fixed port on a valve, pump, or cylinder.
Q2: Do I need thread sealant?
No, not on the JIC end.The 37° Flare (JIC) end creates a metal-to-metal seal and does not require any sealant. You only need to apply sealant to the male pipe or fitting that you install into the female pipe thread port of your equipment.
Q3: What is the difference between the JIC end and the NPT end?
The JIC end has a 37° cone and straight threads, designed to seal against a female flared fitting. The NPT end has tapered threads and is designed to seal within a female tapered port. They are completely different standards and cannot be interchanged.
Q4: Are your JIC adapters interchangeable with Parker Triple-Lok® or Swagelok AN®?
Yes. The 37° Flare end of our adapters is manufactured in strict accordance with the SAE J514 standard, making it fully dimensionally and functionally interchangeable with other compliant fittings, including Parker's Triple-Lok® series and Swagelok's AN® fittings.
